This product is especially suitable for polluted area, high mechanical tensile load and large span and compact line.
It has the feature of light weight, small volume, not easily broken, high mechanical strength, high pollution resistant, good aging resistance, high anti explosive and others.
Product structure and advantages
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.
