BS7835 3 Core Armoured Mains Cable 11kV - XLPE, SWA, LSZH - 35mm to 400mm

Application

The 11KV Medium Voltage British Standard cable is suitable for installation in power networks, underground and in cable ducting. Its low smoke zero halogen sheath makes it suitable for installations where fire, smoke emissions and toxic fumes create a potential threat.

Please note: Due to poor UV resistant qualities, red outer sheath cables are not recommended for outdoor installation.
