Hollow ceramic support insulator is used as high-voltage insulating and sealing through which the discharge electrode suspension rod entering the electric field in an ESP, and in small size ESP it also functions as supporting of the discharge electrode system. By its configuration, it is classified into three types: cylindrical insulator, conical insulator and special-shaped insulator.

Porcelain disc insulators are typically used in power transmission line. Porcelain is the most commonly used insulating material until now. Not only any voltage but also any contamination level can be done by changing number of insulators. TCI porcelain disc insulators have been one of best choice for world’s transmission projects. 

Dimensions: Voltage level: 10-1100 kV. Maximum Height: 12000 mm. Pollution level up to 38mm/ kV.

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.

The HDPE cable spacer shall be made of track-resistant high-density polyethylene which suitable for using in the tropical climatic area and have passed electrical and mechanical test according to ANSI C29 standards. Each cable spacer shall be furnished with cable ties for securing cables. The snap ties shall be made of  UV resistant   polyurethane material which suitable for using in the tropical climatic area.

In the fields of fittings for the substation and transmission line in this world, TCI will be always adapted to local conditions, well-aimed development and production of customer specific components.
