Description:

GN series outdoor high voltage isolator switch is suitable for three-phase AC 50Hz, 10kV/15kV/20kV rated voltage outdoor high-voltage electrical equipment. For high voltage transmission line non-load shifting, and the maintenance of high-voltage Busbar, electrical equipment such as circuit breakers and electrical isolation of live high voltage line. Can also be divided into a small capacitor and the inductor current. Its structure design simple, and reasonable, used copper and the aluminum annex, and stainless steel tight firmware and the hot plating zinc base, has good of anti-dirt and the resistance corrosion capacity, performance reliable, and weight light, and installation convenient, and without periodic cleaning and maintenance, is city and rural 10~20kV distribution line in the for segment, and branch, and maintenance paragraph set obviously disconnect points of price low convenient of outdoor high pressure electrical equipment.

Product structure Our company specially produces composite insulator for power transmission line, the important structure is made of shed housing, epoxy fiberglass core and metal end fittings. The surface of terminal end fittings is covered with zinc coating(hot-dip galvanization) for corrosion protection. Compared with same type ceramic and glass insulator, silicone rubber insulator has the following advantages:
(1)Small volume, light weight(is 1/7~1/10 times than ceramic insulator in the same voltage), sheds have good elasticity, not broken, convenient transportation and installation, economy.
(2)High mechanical strength. FRP ROD has high tensile strength, which is 5-10 times than ceramic materials, for core is small cross section, which makes the products small size, light weight, high tensile strength, and easy to manufacture more than 300KN large tons insulators.
(3)High antifouling property, good aging resistance performance, the sheds made of silicone rubber injection mold has good hydrophobicity and migration, which makes insulator high anti pollution flashover voltage and good electric corrosion resistance.
(4)Easy installation and maintenance, can greatly reduce outage loss which cause due to maintenance and maintenance charges which cause by manual labor intensity.
(5)Simple production process, short delivery time.
