Pairs in layers, ALPSTI sheath
Cables from 2 to 32 pairs, conductor diameter of 0.9 mm with PE insulation. Pairs are stranded into layers to form the core that is protected with a fire-retardant halogen-free (LSZH) ALPSTI sheath. They are used as cables for traffic lights signalling in underground installations for duct or direct burial installations. This sheath provides a special protection against rodents.
