Industrial Cables Single Core Fixed Wiring Cable

6491B to BS 7211

 

Application and Description

6491B to BS 7211 cables are designed for fixed wiring purposes in domestic and industrial power/lighting

applications.6491B to BS 7211 cables 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. 6491B to BS 7211 cables produce no corrosive gasses when

burnt and which is particularly important where electronic equipment is installed. 6491B is equivalent to

harmonized code H05Z-U/ H07Z-U/H07Z-R.
