What is polymeric pin insulator?

HDPE insulators also named polymeric HDPE insulators or High-Density-Polyethelene insulators which were made from a qualified resistive high density polyethelene which are being used in recent years along with its some advantages on environment protection, and easy way to hand and install by man. It is low weight and save costs on transportation. And it is filled with putty to enlarge the puncture ability.

HDPE insulator should be injected with the HDPE material combined with some additives, to provide the ability of anti-UV and anti-aging. The injection machine should be capable enough to inject since the insulators are thick than normal products which need to be injected.

Orient HDPE insulator advantages:

  1. • High quality materials
  2. • All insualtors do X-ray routine test
  3. • No void
  4. • lower prices
  5. • Good package suitable for sea transportationor inland transportation
