Sheathed and Non-Sheathed cables rated, 300/500V and 450/750V are insulated and/or sheathed cables for a variety of application from fixed wiring for power supply to sockets, switches, and lighting fittings of domestic and commercial buildings to flexible installation.
In fixed wiring applications, the cables are installed in conduit in walls or on surfaces. Non-sheathed cables are utilized in the internal wiring of distribution boards and switchboards.
The flexible cables are for connections to moveable equipment. Sheathed cables are either single or multicore cables. Our sheathed and non-sheathed products are BASEC approved, CE marked and manufactured in accordance with BS EN 50525-2-31, EN 50525-2-11, IEC 60227-3, IEC 60227-4, IEC 60227-5, BS 6004, and other customer specification.
