Polymer horizontal line post insulators

Being a prominent polymer insulator manufacturer, exporter and supplier, Orient Power is providing a wide range of polymer horizontal line post insulators.

Localized arcs will be produced which bridged the gaps between water patches and caused erosion of rubber & cracks were developed due to Nitric Acid (by-product of discharges), if the sheath has low hydrophobicity. To improve the performance & life of composite insulators, the electric field on the live end of insulators must not exceed 4.5kV/cm (corona onset for water drops - reference EPRI, USA).

Orient’s housing of polymer horizontal line post insulators are directly injected at high temperature and high pressure on the fiberglass rod and the fittings, assuring a complete adherence and strong bonding of the silicone rubber of polymeric line post insulator.

The core rod is a corrosion resistant glass-fiber-reinforced rod. External metal end fittings are used to transmit the mechanical stresses of the electric line to the central rod. Optimized shed profiles are with large shed tip radius and high protective creepage distance.

Insulator type test only need to be done when develop a new product, and to make type test to make sure the design of the composite insulator is no problem. Whatever your configuration, our polymer horizontal line post insulators have you covered!
