Application
The armoured 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, typically in petroleum industry.The armored versions are generally use for outdoor installation for direct burial or installed in the duct and suitable for wet and damp areas.
