Application of Instrument cable
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.
