Cat 5e Armored Data Cable
Cat 5e Armored Cable for Mechanically Protected Gigabit Ethernet Networks
Cat 5e Armored Cable combines Category 5e Ethernet transmission with additional steel mechanical protection for industrial, infrastructure and physically demanding network routes. ETK Kablo manufactures armored Cat 5e cables with Steel Wire Armor (SWA) or Steel Wire Braid (SWB) and with U/UTP, F/UTP, S/UTP or SF/UTP electrical architectures.
The current ETK Kablo armored Cat 5e portfolio provides transmission performance through 100 MHz for Gigabit-capable Ethernet networks. Published constructions use solid copper conductors, polyethylene insulation, halogen-free inner and outer jackets and either SWA or SWB mechanical protection. Depending on the selected product, the Ethernet core can remain unshielded or include foil, copper braid or combined foil-and-braid screening.
Mechanical armor and electromagnetic shielding perform different functions. SWA and SWB protect the cable mechanically, while U/UTP, F/UTP, S/UTP and SF/UTP describe the electromagnetic-screening architecture of the Ethernet core. Project engineers should specify these requirements separately.
What Is Cat 5e Armored Cable?
A Cat 5e armored cable is a Category 5e balanced copper Ethernet cable that includes an additional steel protection layer around the network cable core.
The armor can provide additional protection for fixed routes where conventional Ethernet cable may face greater physical exposure.
ETK Kablo currently uses two mechanical constructions:
- Steel Wire Armor (SWA)
- Steel Wire Braid (SWB)
Both mechanical families retain Category 5e transmission performance through 100 MHz and can support Gigabit Ethernet when the complete installed channel meets the applicable structured-cabling requirements.
ETK Kablo Cat 5e Armored Cable Range
| Mechanical Protection | Current Ethernet Architectures | Current Jacket System |
|---|---|---|
| Steel Wire Armor (SWA) | U/UTP, F/UTP, S/UTP, SF/UTP | LSOH inner jacket + SWA + LSOH outer jacket |
| Steel Wire Braid (SWB) | U/UTP, F/UTP, S/UTP, SF/UTP | LSOH inner jacket + SWB + LSOH outer jacket |
The current published range therefore allows buyers to select mechanical protection and electromagnetic screening as separate engineering requirements.
Steel Wire Armored Cat 5e Cable
Steel Wire Armored Cat 5e Cable places a steel wire armor layer around the inner-jacketed Ethernet cable core.
The current ETK Kablo SWA construction uses a halogen-free inner jacket around the Cat 5e core. Steel wire armor then surrounds the inner cable, followed by a UV-resistant halogen-free outer jacket.
The SWA layer primarily provides mechanical protection. It should not be confused with Al/PET foil or tinned copper braid used for electromagnetic screening.
The current SWA family includes U/UTP, F/UTP, S/UTP and SF/UTP Cat 5e versions.
Steel Wire Braided Cat 5e Cable
Steel Wire Braided Cat 5e Cable uses galvanized steel wire braiding around the inner-jacketed Ethernet cable core.
The current ETK Kablo SWB construction places the steel wire braid between halogen-free inner and outer jackets.
SWB provides braided mechanical reinforcement around the network cable. It performs a different function from the tinned copper braid used for electromagnetic screening in S/UTP and SF/UTP constructions.
The current SWB family also includes U/UTP, F/UTP, S/UTP and SF/UTP Cat 5e versions.
SWA vs SWB Cat 5e Cable
| Feature | SWA | SWB |
|---|---|---|
| Full Name | Steel Wire Armor | Steel Wire Braid |
| Construction Principle | Steel wire armor layer | Braided galvanized steel wire |
| Main Function | Mechanical protection | Mechanical reinforcement |
| Current Cat 5e Core Options | U/UTP, F/UTP, S/UTP, SF/UTP | U/UTP, F/UTP, S/UTP, SF/UTP |
| Current Jacket System | LSOH / SWA / LSOH | LSOH / SWB / LSOH |
The correct option should follow the mechanical requirements of the cable route. One construction should not automatically be treated as preferable for every installation.
Mechanical Armor vs Ethernet Shielding
Armored Cat 5e cables can contain several metallic components, but each component has a different engineering purpose.
| Component | Main Purpose |
|---|---|
| Al/PET Foil | Electromagnetic screening |
| Tinned Copper Braid | Electromagnetic screening |
| Tinned Copper Earthing Wire | Supports screen continuity and termination |
| Steel Wire Braid | Mechanical reinforcement |
| Steel Wire Armor | Mechanical protection |
This distinction is essential during specification. A Cat 5e cable can contain steel mechanical armor while the Ethernet core remains electrically unshielded.
Likewise, a screened F/UTP, S/UTP or SF/UTP cable can exist without steel mechanical armor.
Cat 5e U/UTP Armored Cable
Cat 5e U/UTP Armored Cable combines an electrically unshielded Category 5e core with SWA or SWB mechanical protection.
The current construction uses solid copper conductors, solid polyethylene insulation and four unshielded twisted pairs.
A halogen-free inner jacket surrounds the Ethernet core before the selected steel protection layer. A halogen-free outer jacket then completes the construction.
U/UTP contains no dedicated foil or tinned copper braid around the data pairs.
Cat 5e F/UTP Armored Cable
Cat 5e F/UTP Armored Cable combines one overall foil screen with SWA or SWB mechanical protection.
The four twisted pairs remain individually unshielded. An overall Al/PET foil and tinned copper earthing wire provide the electromagnetic-screening system.
The cable then receives a halogen-free inner jacket, the selected SWA or SWB mechanical layer and a halogen-free outer jacket.
The foil addresses electromagnetic interference, while the steel layer addresses mechanical exposure.
Cat 5e S/UTP Armored Cable
Cat 5e S/UTP Armored Cable combines an overall tinned copper braid with SWA or SWB mechanical protection.
The four twisted pairs remain individually unshielded. The tinned copper braid acts as the overall electromagnetic screen.
A separate steel armor or steel braid then provides mechanical protection outside the inner jacket.
The copper braid and steel layer should not be confused because they perform different functions and use different materials.
Cat 5e SF/UTP Armored Cable
Cat 5e SF/UTP Armored Cable combines an overall foil and overall tinned copper braid with a separate steel mechanical-protection layer.
The current construction can include:
- Solid copper conductors
- Solid PE insulation
- Four twisted pairs
- Polyester wrapping
- Tinned copper earthing wire
- Overall Al/PET foil
- Overall tinned copper braid
- Halogen-free inner jacket
- Steel wire armor or galvanized steel wire braid
- Halogen-free outer jacket
The foil and tinned copper braid form the electromagnetic-screening system. The separate SWA or SWB layer provides mechanical protection.
U/UTP vs F/UTP vs S/UTP vs SF/UTP Armored Cat 5e
| Architecture | Overall Foil | Overall Copper Braid | Steel Mechanical Protection |
|---|---|---|---|
| U/UTP Armored | No | No | Yes |
| F/UTP Armored | Yes | No | Yes |
| S/UTP Armored | No | Yes | Yes |
| SF/UTP Armored | Yes | Yes | Yes |
The electromagnetic environment should determine whether the project requires U/UTP, F/UTP, S/UTP or SF/UTP. The mechanical conditions should determine whether SWA or SWB is appropriate.
24 AWG Solid Copper Cat 5e Armored Cable
The current published Cat 5e armored constructions use solid copper conductors and 24 AWG designs within the armored family.
Solid copper provides predictable electrical resistance and stable transmission characteristics for fixed Ethernet infrastructure.
ETK Kablo publishes a maximum conductor resistance of 94 Ω/km at 20°C for the current armored Cat 5e products.
Professional buyers should distinguish solid-copper Ethernet cable from copper-clad conductor alternatives where network performance, Power over Ethernet and project specifications are important.
100 MHz Cat 5e Armored Ethernet Performance
ETK Kablo publishes Category 5e transmission characteristics through 100 MHz for the current armored range.
Relevant parameters include:
- Insertion loss
- Near-end crosstalk (NEXT)
- Power-sum NEXT
- Equal-level far-end crosstalk
- Power-sum equal-level far-end crosstalk
- Return loss
- Characteristic impedance
- Propagation velocity
The steel mechanical layer does not change the underlying Category 5e frequency classification.
Cat 5e Armored Cable for Gigabit Ethernet
Cat 5e armored cable can support 1000BASE-T Gigabit Ethernet when the complete installed structured-cabling channel meets the applicable Category 5e requirements.
Potential applications include:
- Industrial Ethernet
- Factory networks
- IP surveillance
- Building automation
- Utility infrastructure
- Warehouses and logistics facilities
- Technical buildings
- Transport infrastructure
- Commercial infrastructure
- Mechanically exposed Ethernet routes
Armor adds mechanical protection. It does not increase the standardized Ethernet bandwidth, data rate or channel distance.
Cat 5e Armored Cable Length
The presence of SWA or SWB does not extend the normal transmission distance of balanced copper Ethernet.
A structured Ethernet channel commonly uses a maximum total length of 100 meters, typically including up to 90 meters of permanent-link cable together with patch and equipment cords.
The steel mechanical protection does not act as a repeater or signal amplifier.
For substantially longer infrastructure routes, fiber optic cable can provide an alternative transmission architecture.
Cat 5e Armored Cable for Industrial Ethernet
Industrial facilities can expose network cables to physical stresses that do not normally occur in protected office pathways.
Cat 5e armored cable provides an additional mechanical layer for fixed Ethernet routes through manufacturing plants, technical areas, warehouses and utility facilities.
Electrical screening should be selected separately. U/UTP can suit controlled electromagnetic environments, while F/UTP, S/UTP or SF/UTP provide different overall screen architectures where required.
Cat 5e Armored Cable for IP CCTV
IP surveillance networks often place Ethernet cabling in technical and externally exposed routes.
Cat 5e armored cable can provide additional mechanical protection for compatible Gigabit-capable CCTV infrastructure.
Screening requirements should follow the electromagnetic conditions of the route, while PoE requirements should follow the electrical and thermal design of the camera system.
Cat 5e Armored Cable for Building Automation
IP-based building systems can use Ethernet for monitoring, control and communication.
Where network routes pass through technical areas with increased physical exposure, armored Cat 5e can provide mechanical protection around the Ethernet core.
The project can then select U/UTP, F/UTP, S/UTP or SF/UTP according to its electromagnetic requirements.
Cat 5e Armored Cable for Cable Trays
Industrial cable trays can contain data, instrumentation, control and power infrastructure within the same facility.
Where the Ethernet route faces greater physical exposure, SWA or SWB can provide additional mechanical protection.
F/UTP, S/UTP and SF/UTP versions can add electromagnetic screening where required.
Applicable separation requirements from power circuits should still be followed.
Cat 5e Armored Cable for Underground Ducts
Armored Cat 5e can be relevant to underground duct routes where the cable requires additional mechanical protection.
However, underground infrastructure can also expose cables to moisture, standing water, pulling tension and other environmental conditions.
These requirements should be specified independently. The presence of SWA or SWB alone should not automatically be treated as proof that a cable suits every underground or flooded-duct installation.
Can Cat 5e Armored Cable Be Direct Buried?
Direct-burial suitability depends on the complete cable construction and the specific installation conditions.
Steel armor provides mechanical protection, but buried routes can also require specific moisture, water-blocking, chemical, tensile or environmental characteristics.
For direct-burial projects, buyers should include route conditions in the RFQ so that ETK Kablo can confirm the required construction.
Cat 5e Armored vs Standard Cat 5e Cable
| Feature | Armored Cat 5e | Standard Cat 5e |
|---|---|---|
| Category Frequency | 100 MHz | 100 MHz |
| Gigabit Ethernet | Supported within compliant channel | Supported within compliant channel |
| Steel Mechanical Protection | Yes | No |
| Electrical Screening | Depends on U/UTP, F/UTP, S/UTP or SF/UTP | Depends on selected Cat 5e construction |
| Main Selection Driver | Mechanical exposure + network requirements | Normal network and environmental requirements |
The steel protection layer is the defining difference. Armor does not create a higher Ethernet category.
Cat 5e Armored vs Cat 5e Aerial Cable
| Construction | Main Mechanical Function |
|---|---|
| Cat 5e Armored | Provides mechanical protection around the cable core |
| Cat 5e Aerial | Uses a galvanized messenger to support an overhead span |
Armored and aerial should not be used as interchangeable terminology.
A messenger wire supports an overhead route. SWA or SWB protects the cable mechanically around its core.
Cat 5e Armored vs Shielded Cat 5e Cable
The words armored and shielded describe separate functions.
Shielding addresses electromagnetic interference.
Armor addresses mechanical protection.
A Cat 5e U/UTP SWA cable is mechanically armored but electrically unshielded.
A standard Cat 5e SF/UTP cable is electrically screened with foil and braid but does not contain SWA or SWB mechanical armor.
Cat 5e Armored vs Cat 6 Armored Cable
| Characteristic | Cat 5e Armored | Cat 6 Armored |
|---|---|---|
| Category Frequency | 100 MHz | 250 MHz |
| Primary Ethernet Positioning | Gigabit Ethernet | Higher-performance Gigabit Ethernet |
| Mechanical Protection | SWA or SWB | SWA or SWB |
| Current Screening Architectures | U/UTP, F/UTP, S/UTP, SF/UTP | According to current Cat 6 armored portfolio |
The armor principle can remain similar while the electrical core changes according to the Ethernet category.
Cat 5e Armored vs Cat 6A Armored Cable
Cat 5e armored cable targets Category 5e networks through 100 MHz and Gigabit Ethernet.
Cat 6A armored cable targets substantially higher 500 MHz performance and 10GBASE-T applications.
The correct category should therefore follow the network requirement rather than the assumption that all armored Ethernet cables provide the same bandwidth.
Cat 5e Armored Copper vs Armored Fiber Optic Cable
Armored copper Ethernet and armored fiber optic cable address different network requirements.
Cat 5e copper provides conventional Ethernet connectivity and can form part of compatible Power over Ethernet systems.
Fiber optic cable provides electrical isolation, immunity to electromagnetic interference and substantially longer transmission distances.
For long inter-building links or electrically complex infrastructure, project engineers should evaluate both technologies before final specification.
LSOH Cat 5e Armored Cable
The eight currently published Cat 5e SWA and SWB products use halogen-free inner and outer jackets.
The current product documentation also publishes smoke, flame, halogen and corrosive-gas test information for these constructions.
LSOH or LSZH describes material and reaction-to-fire characteristics. It should not be interpreted as fire-resistant circuit integrity such as FE180 or PH120.
Cat 5e Armored Cable Electrical Characteristics
| Parameter | Current Published Family Value |
|---|---|
| Conductor Resistance at 20°C | Max. 94 Ω/km |
| Insulation Resistance | 5000 MΩ/km |
| Mutual Capacitance | Max. 56 nF/km |
| Resistance Unbalance | 2% |
| Propagation Velocity | 67–69% |
| Characteristic Impedance | Nominal 100 Ω |
| Operating Voltage | 250 V DC |
| Test Voltage | 1200 V DC for 1 minute |
Cat 5e Armored Cable Mechanical Characteristics
The current published armored constructions use:
- Solid copper conductors
- Halogen-free inner jacket
- SWA or SWB steel mechanical protection
- Halogen-free outer jacket
- Minimum bending radius of 8xD
- 500 m and 1000 m packing options on published armored datasheets
Exact overall diameter, cable weight and operating-temperature requirement should be confirmed from the selected product documentation during quotation.
Cat 5e Armored Cable Standards
The current Cat 5e armored product documentation references:
- ANSI/TIA-568-C.2
- IEC 61156-5
- IEC 11801
The published transmission tables extend through 100 MHz.
Project specifications can require different standard editions, CPR classifications or additional documentation, so procurement teams should verify the exact supplied construction.
Cat 5e Armored Cable and Power over Ethernet
Cat 5e armored cable can form part of compatible Power over Ethernet systems.
The SWA or SWB layer does not determine PoE capability. Remote powering depends primarily on the copper-pair electrical characteristics and thermal conditions of the installed system.
Relevant factors include:
- Conductor resistance
- Resistance unbalance
- Network distance
- Cable bundle size
- Ambient temperature
- Installation pathway
- Required PoE level
Mechanical armor should therefore be evaluated separately from the PoE electrical and thermal design.
