Pin insulators ,also called polymer pin insulators or pin composite insulators.
Voltage level 10-220kV
Rated bending load 1-160kN
Polymer pin insulators are highly resistant to bending, impact, shock and explosion. The internal insulation is reliable and the weight is light, which is an ideal replacement for traditional electric porcelain.
Conditions of Use:
·Ambient temperature -40 ° C ~ +40 ° C
