Low Voltage Aerial Bundle Cable

Low-voltage overhead insulated cables are mainly used to transmit power from distribution transformers to the customer end (e.g. residential homes, small commercial facilities, etc.). The insulation requirements are also relatively low, and insulating materials such as polyvinyl chloride (PVC) can be used at a relatively low cost, while also providing sufficient insulation protection against leakage and short-circuiting of low-voltage lines. The laying requirements of low-voltage overhead cables are relatively flexible and the safety distance requirements are relatively small. In some residential areas and other places, it can be laid closer to the building or ground under the premise of ensuring safety according to the actual situation, in order to facilitate the supply of electricity to the user terminal.

STANDARD TAXNOMY

Cables are offered accords with GB/T 12527-2008.

CONSTRUCTION

Conductor: Optional of copper wire, aluminum wire, aluminum alloy, and aluminum conductor steel reinforced
Number of Cores: 1, 2, 3, 4, 3+k (A), 3+k (B)
Nominal Cross Sectional Area/mm²: 10-400
Note: k is the neural conductor with bearing. (A) refers to steel bearing wire core, and (B) refers to aluminum alloy bearing wire core. The cross section can be chosen for pairing up with the major core according to the requirements of the power distributing project.
Conductor screen: Extruded semiconducting layer
Insulation: Optional of Polyethylene(PE), Cross-Linked Polyethylene(XLPE) and Polyvinyl Chloride(PVC)
