Product Description

Product Description

Porcelain insulators are the most widely used insulation material in power line grid. According to application, they are classified by disc type (suspension), pin type, stay type, shackle type and so on. With different hardwares they can be used for suspension & tension, distribution and stay purpose.

Disc and suspension insulators have advantage of good insulation performance and long working life. It is flexible to connect several discs together to meet 10kv-800kv system voltage in overhead line.

Post Insulator is usually bigger size and used in high voltage substation to support conductor. It can be also used as disconnector switch support. 

Pin and pin post insulator is mostly for distribution line using, on 11kv-66kv suspension pole, or as jumper support on tension pole. 

Shackle insulator is often used for 400V-1KV line, to fix bare conductor or insulated cable. 

Stay insulator as safety protection is installed in pole stay system.

We can supply all these insulators and welcome global customers to make business together. Please feel free to contact us if you have inquiry or need any support.

We are TRIGOLD POWER CO., LTD established for power line products with more than 30 years experience. We have owned our manufacturing plants to produce most of the materials for transmission line and substation. Our business scope is mainly Europe,Asia and Africa countries.

 

One of our main products is porcelain insulator for up to 500kV overhead line and for distribution as well, such as suspension insulator, post insulator, pin insulator, spool and strain insulator. Our porcelain suspension insulator is proved as best quality in the type test by KEMA lab (a member of STL) in Netherland.

 

Another main product is polymer insulator for up to 220kV transmission line, including suspension type, pin type and post type for horizontal mounting.

 

The last core business is hardwares including power fittings and steel structure. We could make various accessories up to 500kV for transmission line and substation. Our product range include aluminum alloy clamps, casting and forged steel fittings, preformed dead end and armor rod, PG clamps, OGW fittings and so on. We are able to supply complete suspension strings and tension strings accodring to customer specificaton.

 

We have full quality assurance system and ISO 9001 certificate to ensure our products quality and to meet the relevant standard. We could supply the products in accordance with IEC, ANSI, ASTM, AS, BS, DIN or ISO standard.
