Composite long rod insulator,500KV composite suspension insulator

Composite long rod insulator consists of FRP core, silicone rubber shed, housing and end fittings, which is also called composite suspension insulator. Composite suspension insulator voltages levels comprise consist of 110KV, 330KV, 400KV, 500KV, 750KV and so on. 500KV composite long rod insulator is a main kind composite insulator.

Composite insulator comprise function:
FRP core is the skeleton of composite long rod insulator, plays an umbrella cover, inner insulation and hardware on both ends of the connection, and withstand the mechanical load multiple role. Composite insulator FRP core has very high tensile strength, good dielectric properties, and chemical corrosion resistance, to bending fatigue, creep resistance and impact resistance. Silicon rubber housing main protect a core rod, block rain and snow, increase the creep age distance and the effect of external insulation products, is a polymer of silicone rubber as the matrix, complementary with flame retardant, anti-aging agent, coupling agent, such as packing by high temperature and pressure curing. Silicone shed has the good hydrophobic and mobility, as well as good corrosion resistance, ageing resistance, electric insulation performance, etc. And polymer insulator has the very high slop lightning and ground resistance, uniform voltage distribution, compared with porcelain insulator the flashover voltage under the same conditions is more than 2 times of porcelain.

Composite long rod insulator:
Composite long rod insulator is one kind of the high voltage polymer insulators. 500kv composite suspension is usually used on distribution and transmission lines in the electrical industries. We are one of the main manufacturer and suppliers in China. We produce varied composite insulators from 10kv to 1000kv with high quality and competitive composite insulator price.
