Polyester Busbar Standoff Insulators Middle Voltage 10KV 50mm

Standoff insulators from HAITAN are ideal for supporting busbars or other live electrical components. These components are made of UL-recognized fiberglass-reinforced, flame-retardant, thermoset polyester molding compound with strong mechanical and electrical insulating properties.

They are shatter-resistant and have tighter height tolerances than those typically available in porcelain insulators. These insulators have higher moisture and heat resistance than traditional plastic insulators.

The insulator is the special part to fix, install and insulate on communication, electric power, lightning protection, machinery, medical, wind energy, frequency conversion equipment, new energy vehicles (integrated chassis cabinets, locker, etc.) to provide meet the fixed support, installation and insulation isolation effect of special parts, it is also known as insulators, insulation column. Its appearance is usually cylinder, hexagonal, and round. There is an insert on the two surfaces of the insulator.


1. High intensity

2. Electrical resistance

3. Heat, fire, water resistance

4. Low shrinkage


Insulators are mainly used in power-related industries and play an insulating role in power systems. It can be used in power-related industries such as the power transmission and distribution industry, the 5G communication industry, solar energy, wind energy industry, and automobile industry.
