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

 

Applications :

  • The armoured fire resistant versions (Part 1 Type 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
    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
