6242B 6243B LSZH Flat Cores +Earth Cable

CU/LSZH/lszh flat cable are the electric cables referred to thermosetting insulated and thermoplastic sheathed cables for voltage 450/750V electric power and lighting and having low emission of the smoke and corrosive gases when affected by the fire.

624-B refers to thermosetting insulated and sheathed cables, single core 6241B cable, flat twin-core 6242B cable, flat 3-core 6243B cable, with circuit protective conductor (CPC) 300/500V. The conductor is annealed copper conductor of class 1 or class 2. The maximum size is up to and including 16 mm². We supply the cables according to BS7211.

Application Of 6242B 6243B LSZH Flat Cores +Earth Cable

6241 B LSZH cables are widely used in domestic and industrial power or lighting system. They normally installed in conduit and trunking or can be surface nounted if used as earth cable. They are good options for using in public buildings to reduce the threat to life and equipment cased by smoke and toxic fumes. They can't be installed incontrete without mechanic protection.
