Polymer Pin insulators are devices installed between conductors at different potentials or between conductors and grounding components that can block voltage and mechanical stress.
This kind of insulator is high bending resistance, excellent impact resistance, shock resistance and explosion-proof performance.
It is reliable in quality and light in weight and is the ideal replacement product for traditional tempered glass insulators.
We have 9 types to meet your needs.
