Polymer post insulators

Polymer post insulators are outdoor solid core post insulators used for frequency AC 10kv to 500kv outdoor substations, stations and apparatus electrical equipment for supporting and insulating.

Polymer post insulators

The service conditions of Polymer post insulators
◆ Used for -40℃ to +40℃
◆ Some of insulators can be used above altitude 4000m areas
◆ Can be used in heavy or heavier contamination areas

The features of Polymer post insulators
◆ Good hydrophobicity
◆ Aging resistance
◆ Resistance to tracking
◆ Resistance to electrical erosion resistance
◆ With high tensile strength and flexural strength
◆ Impact resistance
◆ Good shockproof and anti-brittle breaking performance
◆ Light weight, easy installation and maintenance

Polymer post insulators are one of solid core insulators used with flange, and designed in different types. Different types of polymer post insulator have different section length and creepade distance.
