BS 5308 Cables

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

Application

BS5308 Cable Part 1 Type 2 MG-XLPE-OS-SWA-LSOH are typically used in chemical and process industries where

there is danger of fire. The galvanised steel wire armour provides excellent protection.

Construction BS 5308 Cables

Conductor Annealed 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
