Braid Screened Steel Wire Braided Signal Control Cable

Braid screened steel wire braided signal control cables combine a tinned copper electromagnetic screen with a separate galvanized steel wire braid for additional mechanical protection.

ETK Kablo manufactures this cable range in LIYCYSWBY and LI2YCYSWBY constructions. Standard multicore and TP/TT versions provide different conductor arrangements for industrial signal and control circuits.

The tinned copper braid surrounds the signal core and provides electromagnetic screening. A PVC inner jacket separates this screened core from the galvanized steel wire braid, which provides a separate mechanical reinforcement layer.

What Is a Braid Screened Steel Wire Braided Signal Cable?

A braid screened steel wire braided signal cable contains two different braided metallic layers with different functions:

• tinned copper braiding for electromagnetic screening,
• galvanized steel wire braiding for mechanical protection.

The copper braid helps protect sensitive signal circuits against electromagnetic interference from nearby electrical equipment, drives, motors and power circuits.

The galvanized steel wire braid surrounds the PVC inner jacket and provides additional physical protection.

Although both layers use a braided construction, they should not be treated as interchangeable.

Tinned Copper Braid vs Galvanized Steel Wire Braid

Understanding the two braid layers is essential when specifying this cable family.

Construction Element	Material	Main Function
Electromagnetic Screen	Tinned copper braiding	Electromagnetic screening
Inner Jacket	UV-resistant PVC	Separates the screened cable core from the mechanical braid
Mechanical Braid	Galvanized steel wire braiding	Mechanical reinforcement and protection
Outer Jacket	UV-resistant PVC	External cable protection

The tinned copper braid is therefore part of the electrical screening system.

By contrast, the galvanized steel wire braid primarily forms the mechanical protection system.

LIYCYSWBY and LI2YCYSWBY Cable Constructions

ETK Kablo manufactures two principal conductor-insulation systems within this range.

Cable Family	Conductor Insulation	Electromagnetic Screen	Mechanical Protection
LIYCYSWBY	PVC	Tinned copper braid	Galvanized steel wire braiding
LI2YCYSWBY	Solid polyethylene	Tinned copper braid	Galvanized steel wire braiding

Both families use Class 5 stranded electrolytic copper conductors together with UV-resistant PVC inner and outer jackets.

The principal difference lies in the conductor insulation.

LIYCYSWBY uses PVC conductor insulation, while LI2YCYSWBY uses solid polyethylene conductor insulation.

The 2Y designation therefore identifies the polyethylene conductor-insulation system. It does not indicate a different electromagnetic screen, mechanical braid or jacket system.

PVC Inner and Outer Jackets

The current ETK Kablo constructions use UV-resistant PVC for both the inner and outer jackets.

The PVC inner jacket surrounds the copper-braid-screened signal cable before the galvanized steel wire braid is applied.

The PVC outer jacket then covers the complete steel-wire-braided construction.

Current product data identifies the standard jacket color as RAL 7035 grey.

These products belong to the PVC signal-control range and should remain distinct from corresponding LSZH constructions that use halogen-free jacket materials.

Standard and TP/TT Versions

The current category contains standard multicore and TP/TT versions.

Version	Conductor Arrangement	Electromagnetic Screen	Mechanical Layer
Standard	Cores stranded in layers	Overall tinned copper braid	Galvanized steel wire braid
TP/TT	Twisted pairs or triads	Overall tinned copper braid	Galvanized steel wire braid

This category does not currently contain PiMF/TiMF versions.

What Do TP and TT Mean?

TP refers to conductors arranged as twisted pairs, while TT refers to conductors arranged as twisted triads.

In LIYCYSWBY-TP/TT and LI2YCYSWBY-TP/TT cables, insulated conductors are first stranded into pairs or triads. The resulting groups are then stranded together before the overall tinned copper braid is applied.

TP/TT therefore describes conductor organization.

It does not mean that every pair or triad receives an individual metallic screen.

The current TP/TT products use one overall tinned copper braid around the assembled cable core.

ETK Kablo Braid Screened Steel Wire Braided Cable Range

Product	Insulation	Configuration
LIYCYSWBY Signal Control Cable	PVC	Standard multicore
LIYCYSWBY-TP/TT Signal Control Cable	PVC	Twisted pairs / triads
LI2YCYSWBY Signal Control Cable	Solid polyethylene	Standard multicore
LI2YCYSWBY-TP/TT Signal Control Cable	Solid polyethylene	Twisted pairs / triads

Electrical and Mechanical Characteristics

The current ETK Kablo products use Class 5 stranded electrolytic copper conductors according to IEC 60228, EN 60228 and DIN VDE 0295.

Published conductor cross-sections range from 0.22 mm² to 2.50 mm². Available conductor counts and pair or triad configurations depend on the selected product.

Current product data publishes:

• 250 V DC operating voltage for applicable smaller cross-sections,
• 300/500 V operating voltage for applicable larger cross-sections,
• minimum bending radius of 7.5 × overall cable diameter,
• operating temperature range of -30°C to +70°C.

The selected product datasheet should determine the exact electrical and mechanical values for each project.

Flame Retardancy

The current products publish single-cable flame-retardancy testing according to:

• IEC 60332-1-2,
• VDE 0482-332-1-2,
• BS EN 60332-1-2.

Flame retardancy should not be confused with fire resistance.

Standard LIYCYSWBY and LI2YCYSWBY cables should not automatically be specified as FE180 or PH120 fire-resistant cables. Projects requiring circuit integrity during fire exposure need a dedicated fire-resistant cable construction with the required classification.

Typical Applications

Braid-screened steel wire braided signal control cables can suit fixed industrial installations where signal circuits require electromagnetic screening together with additional mechanical protection.

Typical applications include:

• industrial automation systems,
• process control installations,
• measurement and monitoring circuits,
• PLC and control-system connections,
• sensors and actuators,
• factory and production infrastructure,
• building automation systems,
• signal circuits in mechanically exposed fixed routes.

The final cable selection should consider signal sensitivity, surrounding electrical noise, mechanical exposure and installation conditions.

Braid Screened vs Foil Screened Steel Wire Braided Cable

The main difference lies in the electromagnetic screening system.

The Foil Screened Steel Wire Braided Signal Control Cable range uses Al/PET foil with a tinned copper earthing wire.

The products on this page instead use a tinned copper braid as the dedicated electromagnetic screen.

Both families use galvanized steel wire braiding as their mechanical protection layer.

Construction	Electromagnetic Screen	Mechanical Protection
Foil Screened	Al/PET foil + tinned copper earthing wire	Galvanized steel wire braid
Braid Screened	Tinned copper braid	Galvanized steel wire braid

Braid Screened vs Braided Foil Screened Cable

For projects requiring both foil and copper-braid electromagnetic screening, ETK Kablo also manufactures Braided Foil Screened Steel Wire Braided Signal Control Cables.

Those products use Al/PET foil together with a tinned copper braid as the electrical screening system.

By contrast, the products on this page use the tinned copper braid without an additional overall foil screen.

Both constructions retain a separate galvanized steel wire braid for mechanical protection.

All screening options belong to the broader Steel Wire Braided Signal Control Cable range.

Steel Wire Braided vs Steel Wire Armored Signal Cable

Steel wire braid and steel wire armor are separate mechanical constructions.

The products on this page use galvanized steel wire braiding.

They should therefore not be described as Steel Wire Armored (SWA) products merely because both cable families provide additional mechanical protection.

The project specification and required mechanical construction should determine whether a steel wire braided or steel wire armored design is appropriate.
