66/69KV composite suspension insulator or 69 KV polymer suspension insulator has a better performance for its advanced process, accurate technical data and raw materials.

66/69KV composite suspension insulator or 66 kv tension insulators raw materials:
There are three main raw materials for 69 KV polymer suspension insulator or 66 kv tension insulators, and they are silicone rubber, fiber glass rod and end fitting. Before moulding, these raw materials will be treated first.

The 66/69KV composite suspension insulator manufacturing process first stage:
Silicone rubber: First, mix the silicone rubber raw material and test silicone rubber, then it will be the silicone rubber used for production.
End fitting: It is simple for end fittings, Orient Power will do inspection and cleaning for them before using.

The 69 KV polymer suspension insulator manufacturing process second stage:
Assembly of fiber glass rod and end fitting, then pre-crimping
Moulding or whole injection the silicone rubber on the crimped fiber glass and end fitting assembly

The 69 KV polymer suspension insulator or 66 kv tension insulators manufacturing process final stage:
Second time crimping on end fitting hardware, polymer suspension insulators surface trimming, do routine test and sample test according to IEC61109
