HDPE insulators are mainly have pin types, spool type and line post type. Mostly under 35kv transmission lines. since HDPE insulators are light, it is easy to store, transport, handle and install. It is hard to broke and have better performance on the electrical and mechanical.
HDPE insulators can replace ANSI standard porcelain pin insulators, such as 55-3, 55-4, 55-5, 55-6, 56-1 and so on. It will be assembled with spindle, lead head or plastic head will be better.
Orient Power can supply HDPE insulators together with plastic head spindle glued together, or only the HDPE insulators filled with putty.
The biggest advantage is the HDPE can be 100% recycable. It protect the environment and will benefit all the human beings.We inspect every insulator by a laser to make sure there is no voids, and do puncture test to make sure the better electrical ability.
Polymeric/plastic coachscrew insulator:
Normally low voltage coachscrew insulator which is used on wooden electical poles, is made of porcelain, but porcelain coachscrew is easy to break, hard to get high strength, with bad appearance, so now we developed plastic ones, and it proofs excellent strength and look outlook, longer user time, and is popular in customers now. It is replacing traditional porcelain types.
Polymeric insulator has the following Characteristics:
1. Excellenct Track-Resistant
2. High Chemical Resistance
3. Unbrakable and Light Weight
4. Easiest Handling and Transportation
5. Low Initial Cost
6. Long Service Life
7. Durable Metal Treads
8. Water Repelling Surface
9. High resistance to traction, flexion and impact
10. May be fixed by elastomeric ring or preshaped plastic lace
Composite pin type insulator tensile strength is 4kN, 6kN, 8kN, 10KN,11kN, 12.5KN, 12KN, 13kN, and the voltage is 6kv, 10KV, 11KV, 12KV,15KV, 20KV, 22KV, 24KV, 25KV, 27KV, 33kV, 35KV, 36KV. Composite pin insulators are made of HTV silicone rubber, HDG metal end fittings and ECR fibreglass rod core. Polymeric Insulators are widely used in stead of ceramic insulators. Orient Power can manufacture polymeric insulator as per the standard profile or the specifications of clients.
