Product name:
Composite insulators
(belongs to insulators)
Product summary:
1.silicon rubber, composite polymer.
2. glass-fiber reinfored epoxy resin rod
3. hot-dip galvanized steel
4.System nominal voltage(kv):35-500kv.
5.Rated mechanical tensile load (kv):70-400kv
Product feature:
These products are composed of the epoxy resin glass fiber pull rod,silicone rubber sheds,both ends of  the connection fittings and end fittings.
They have the merits such as small size,light weight,high mechanical strength,good pollution proof performance and maintenance-free compared with porcelain insulators and glass insulators.
They have been used in electrical transmission line and electrified railway more and more widely.
