RE-2X(St)H Halogen-Free Instrumentation Cable for Process Control Systems
ETK Kablo’s RE-2X(St)H Instrumentation Cable is designed for secure, low-interference signal transmission in process control, industrial automation, and measurement systems. Engineered for precision and durability, this cable ensures reliable communication between field instruments and control equipment even in harsh or noise-sensitive environments.
Construction and Shielding Design
The RE-2X(St)H cable features individually insulated twisted pairs with an overall aluminum foil screen (St) that provides strong EMI protection against external electrical noise. This shielding minimizes signal distortion and ensures accurate data transmission over long distances in DCS, PLC, and SCADA systems.
Halogen-Free and Flame-Retardant Performance
Its LSZH (Low Smoke Zero Halogen) outer sheath guarantees low smoke emission and halogen-free safety, making it suitable for public buildings, tunnels, offshore platforms, and industrial facilities where fire safety is a priority. The cable complies with IEC 60332-3 and related flame retardancy standards.
Applications and Electrical Characteristics
Rated at 300/500V, this halogen-free instrumentation cable is intended for fixed installations in dry or humid areas. It delivers consistent performance in chemical plants, oil & gas refineries, power generation units, energy systems, and manufacturing automation networks. The robust construction offers superior resistance to mechanical, chemical, and thermal stress.
Ease of Installation and Customization
The individually twisted pairs reduce crosstalk and allow for high signal integrity across long cable runs. Conductor identification can be tailored to project requirements — including black with white numbering or colored cores — to simplify installation and maintenance in complex control systems.
Why Choose ETK Kablo’s RE-2X(St)H Cable?
Choose ETK Kablo’s RE-2X(St)H Instrumentation Cable — the halogen-free, EMI-protected solution that combines fire safety, reliability, and signal accuracy for demanding industrial and process automation applications.
Frequently Asked Questions about Instrumentation Cables
What is an instrumentation cable?
Instrumentation cables are specialized signal cables designed for accurate data and control transmission between field devices and monitoring systems. They ensure low-noise communication in industrial automation, process control, and measurement applications by minimizing interference and maintaining signal integrity.
What is the difference between electrical cable and instrumentation cable?
Electrical cables carry power or current to operate equipment, while instrumentation cables transmit low-level signals for monitoring, control, and communication. Instrumentation cables, such as RE-2X(St)H, include shielding (foil or braid) to protect sensitive signals from electromagnetic interference (EMI).
How many types of cable are in instrumentation?
Instrumentation cables are generally categorized as unarmored or armored types and can include individual pair-screened, collectively screened, or overall-shielded designs. Common constructions include RE-2X(St)Y, RE-2X(St)H, and RE-2X(St)YSWAY for varying levels of EMI protection, flexibility, and fire performance.
What is the IEC standard for instrumentation cable?
The main international reference is IEC 60332 for flame retardancy and IEC 60092-376 or IEC 60502 for construction and testing. The RE-2X(St)H cable complies with these standards, meeting halogen-free, low-smoke, and screened signal cable requirements for industrial use.
What is the voltage of instrumentation cable?
Typical instrumentation cables operate at 300/500 V (U₀/U) according to VDE 0815 and IEC 60332. This rating is sufficient for low-voltage control and monitoring circuits used in DCS, PLC, and SCADA systems.
