We sell the disc hanging tempered glass insulating products, used in transmission line insulation and high pressure and super high pressure suspension wire, the electrical and mechanical performance and safety performance are currently the level advanced in the world. Using voltage 10-750kv, tolerance range 40-550000 cattle. The products have four series (standard, pollution-resistant, aerodynamic and linear) nearly 100 varieties. The performance of tempered glass insulator compared with ceramic insulator and silicone rubber has unique advantages: 1, the main large capacity, uniform chain tension distribution, long service life; 2, zero since the break, facilitate testing; 3, self-cleaning performance is good, not easy aging. Therefore, in similar products in the tempered glass insulator have a stronger competitive advantage in the market.
