    Application and Description

    These cables are designed for fixed wiring purposes in domestic and industrial power/lighting applications. They can be used in trunking or conduit, or may be surface mounted when used for earthing. and they are generally in areas (such as public and government buildings) where smoke and toxic fumes may cause a threat to life and equipment. The cables produce no corrosive gasses when burnt and which is particularly important where electronic equipment is installed. 6491B is equivalent to harmonized code H07Z-U/ H07Z-R/H07Z-K.

    Cable Construction

    • - Bare copper made of solid/strands conductor
    • - Solid to BS 6360 CL-1 or IEC 60228 CL-1(H07Z-U)
    • - Stranding to BS 6360 CL-2 or IEC 60228 CL-2(H07Z-R)
    • - Stranding to BS 6360 CL-5 or IEC 60228 CL-5(H07Z-K)
