The HDPE Insulator is 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.
It is molded in one-piece with fire retardant fiber filler. Representing the largest portion of the polyethylene, HDPE polymer offer the excellent chemical resistance, good electrical properties, low moisture absorption, and high tensile strength. HDPE polymer is also non-toxic, non-staining and recyclable. It is not recommended using metallic string in compacted or conventional networks.
