 BS5308 Part 1 / Type 1 (unarmoured cables)
BS5308 Cable Part 1 Type 2 XLPE-OS-SWA-LSOH

Application

The armoured LSOH versions (Part 1 Type 2) are generally used when the risk of mechanical damage is increased. The galvanised steel wire armour provides excellent protection. Generally used within industrial process manufacturing plants for communication, data and voice transmission signals and services, Also used for the interconnection of electrical equipment and instruments, the LSOH sheath can reduce toxic smoke and fume emission.

Construction

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

Conductor Annealed copper, sizes: 0.5mm² and 0.75mm² mulitistranded(Class 5), 0.5 mm², 1.0 mm² solid(Class 1), 1.5mm² or 2.5mm² multistranded(Class 2) to BS6360
Insulation XLPE (Cross Linked Polyethylene), or PE (optional)
Pairing Two insulated conductors uniformly twisted together with a lay not exceeding 100mm
