H07V-K – Flexible PVC Insulated Wire
Fine-stranded copper single-core wire for electrical installations, distribution boards, switchgear and internal machinery wiring.
Product Overview
H07V-K is a flexible, PVC-insulated single-core installation wire with fine-stranded Class 5 bare copper conductors and a nominal voltage of 450/750 V.
It is designed for laying in conduits installed on or under plaster, in closed installation ducts and for internal wiring of machinery, switchgear and electrical distribution systems.
The wire is flame-retardant according to IEC 60332-1-2 and classified Eca under EN 50575.
