insulated wire messenger cable
An insulated messenger wire cable consists of between one and five weather resistant, high density or cross-linked, black, polyethylene insulated conductors which are twisted around an insulated aluminium alloy messenger with a typical tensile strength 300 N/mm².
The messenger, which is also the neutral conductor, takes all of the mechanical stress.
The cross section of the phase conductors can vary from 16 to 185 mm² to meet the load current, maximum acceptable voltage drop and short circuit current of the network.
