Product Information
Composite Cross-arm Insulator
This product is applicable to the technical reform of city network, which can effectively use narrow corridor area of city to boost power transmission, can reduce the height of tower, save lots of financial and material resources. Because of its high bending strength, it can prevent fracture accidents which easily happen in porcelain cross arm insulator, and it has good pollution resistance, porcelain cross arm can not be replaced.

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.
