Disc insulators are the most widely used insulation material in power line grid. According to material, they are classified by porcelain, glass and polymer. With different hardwares they can be used for suspension or tension target.
Porcelain disc insulators have advantage of good insulation performance and long working life. It is flexible to connect several discs together to meet various system voltage requirements.
Glass disc insulators have same looking structure as porcelain disc. Comparing to porcelain, glass insulators are made by toughened glass, which is strong anti-break when installation and transport.
Polymer insulators are the new member of insulators in the last several decades. The silicone rubber housing and a fiberglass core combine to main part of the insulator. The advantage is light weight and only piece insulator needed for each insulator sting.
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.With excellent quality, outstanding service and reasonable price, we warmly welcome friends in all over the world to establish a mutual cooperation relationship with us to reach great development together.
