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.
