25mm 4 Core Steel Wire Armoured SWA Cable made up of a black PVC sheath, XLPE insulation, copper conductors, and steel wire armoring. This type of cable is designed for mains electricity in various applications, including laying underground, power networks, and incoming mains to homes amongst a host of other uses externally and internally.
25mm 4 Core Steel Wire Armoured SWA Cable is suitable and often used for direct burial, with the steel wire armoring providing further protection from external damage. The XLPE insulation is resistant to several different fluids, and chemicals and has good heat stability, as well as being UV Resistant.
25mm 4 Core Steel Wire Armoured SWA Cable Standard
BS 5467, IEC/EN 60502-1, IEC/EN 60228, Flame Retardant according to IEC/EN 60332-1-2
Conductors: Plain circular, compacted, or shaped stranded copper or aluminum conductor (Conductor shaped: RE=circular solid, CC=compacted circular stranded, SM=sector shaped stranded)
Insulation: XLPE (cross-linked polyethylene) rated at 90°C
Color identification
1 Core: Red or Black, 2 Cores: Red, Black, 3 Cores: Red, Yellow, Blue, 4 Cores: Red, Yellow, Blue, Black, 5 Cores: Red, Yellow, Blue, Black, Green
