UNIMA CABLE | HALOGEN-FREE BUILDING WIRES
H07Z-K – Halogen-Free Flexible Wire
Low-smoke, halogen-free single-core installation wire with fine-stranded copper conductor and cross-linked polyolefin insulation for protected wiring in buildings and electrical equipment.
Product Overview
H07Z-K is a halogen-free, flexible single-core wire for installation in conduits, pipes, enclosed cable ducts and electrical distribution equipment.
The conductor is bare copper, Class 5 fine-stranded, insulated with cross-linked halogen-free polyolefin compound EI5.
The wire is designed for locations where reduced smoke and halogen emissions are important, including public buildings, electrical switchboards and transport applications.
