Construction Application area Technical data Calculated data

Number of pairs in the cable

12; 4; 8; 12; 16; 20; 32 and 40.

Current-carrying conductor

Copper or tin-plated copper, nominal diameter 0.8 mm (area 0.5 mm²).

Insulation

Halogen-free polymer composition. Color coded.

Core arrangement and twisting

Two insulated colour-coded strands are twisted into a pair.

The pairs are twisted into elementary four-pair bundles, with elementary bundles twisted into a core.

Belt insulation

PET-E tapes wound (helically with overlap) over the twisted core (two- and four-pair cable) or elementary bundle.

Screen

Aluminium polymer tape wrapping (helically with overlap) and tin-plated copper contact wire.

Over sheath

Grey Halogen-free polymer composition.

The cables are designed to transmit signals of up to 250VAC, 50 Hz or up to 350VDC/300mA when connecting detectors and actuators to SCADA hardware and software and to be used in the process areas outside the containment building of nuclear power stations, classes 3N, 3U, 4N and 4U as per NP-001 (rules and regulations).
