BS5308 Cable Part 1 Type 2 MG-XLPE-IS-OS-SWA-LSOH

 

Applications :

  • The armoured fire resistant versions (Part 1Type 2) are typically used in chemical and process industries where there is danger of fire. The galvanised steel wire armour provides excellent protection.

Construction :

  • Conductor Annealed or tinned copper, Class 2
    Insulation Mica glass tape, XLPE (Cross Linked Polyethylene), or PE (optional)
    Pairing Two insulated conductors uniformly twisted together with a lay not exceeding 100mm
    Colour code See technical information
    Individual screen Aluminium/polyester tape is applied over each pair metallic side down in contact with
    tinned copper drain wire, 0.5mm²
    Binder tape PETP transparent tape
    Collective screen Aluminium/polyester tape is applied over the laid up pairs metallic side down in contact with
    tinned copper drain wire, 0.5mm²
    Inner Sheath LSOH(Low Smoke Zero Halogen) sheath
    Amour Galvanized steel wire armour
    Outer sheath LSOH(Low Smoke Zero Halogen) sheath
    Flame retardant to IEC60332-3-22
    Fire resistant to IEC60331
    Halogen free to IEC60754-1
    Low smoke emission to IEC61034-1-2
    Sheath colour Black or blue
