BS5308 Part 1 / Type 1 (unarmoured cables)
BS5308 Cable Part 1 Type1 XLPE-OS-LSOH
Application
The unarmoured LSOH versions (Part 1 Type 1) are generally use for indoor installation and suitable for wet and damp areas. 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.
