BS 7211 Cables

6491B Conduit Wiring Cable

6491B is equivalent to harmonized code H07Z-R, these cables are designed for fixed wiring purposes in

domestic and industrial power/ lighting applications. Can be used in trunking or conduit, or may be surface

mounted when used for earthing. and 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 which is particularly important where electronic equipment is installed.
