U70BS (127/255/320) Glass Insulator
70kN glass insulator is a component used to suspend power lines on high-voltage poles or towers.
- To secure the power line like a safety rope: It withstands the weight of the wire itself and the immense tension from wind and ice, ensuring line stability.
- To isolate electrical current like a firewall: It prevents high-voltage electricity from directly grounding through the tower, ensuring safe power transmission.
- Brand: QOCI
- Catalog ID: UG70B127/320N
- Type: Standard Type
- Material: Glass Dielectric ， Forged steel cap & pin
- Place of Origin: Jiangxi
