The quadruplex cables are suitable for use as drop cable from a pole-mounted transformer,to the service entrance of a structure,or as secondary distribution between poles.The cables should be limited to the voltages of 0.6/1 kv or less (phase to phase) at conductor temperatures not to exceed 75°C for polyethylene insulation conductors or 90°C for crosslinked polyethylene(XLPE) insulated conductors.

This is a kind of climate bearable XLPE insulated aerial cables of aluminum core,aluminum conductor steel reinforced core or aluminum alloy core, suitable for overhead power line of AC rated voltage Uo/U 0.6/1KV and below.

It is widely used in power transmission lines and electricity distribution lines, because they have such good characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity. And they are also suitable for laying across rivers valleys and the places where special geographical features exist.
