Flame Retardant Instrumentation Cables

Application

The unarmoured LSZH versions (Part 1 Type 1) cables 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 LSZH sheath can reduce toxic smoke and fume emission.

Standards

Basic design to BS 5308 Part1 Type1 & 2
