High-density polyethylene insulator (HDPE insulator) or plastic insulator can used in overhead electrical distribution system, compacted or conventional distribution aerial nets. It suits for polluted area or salty coastal area in tropical zone. HDPE insulators can be applied with jacketed or bare overhead conductors, aluminum or copper. Mainly applied in electrical system of 15KV, 25KV and 35KV.
HDPE pin insulators are designed to support distribution and sub-transmission conductors, typically in a vertical orientation, by threading the insulator on to a pin installed on the crossarm or pole. Conducting cables are secured to pin insulators with the use of wire ties.
