BS 7211 Cables
Thermosetting insulated,
single-core, sheathed cables
Application and Description
BS 7211 single core 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.
