Polymer-Based Overhead Protection Equipment

Polymer Housed Lightning Arrester with Lead Wire

This is a device installed on overhead power distribution lines to limit sparks and surge voltage from switching, and blocks follow current to protect electrical equipment.

Product Specification

Enhancing Reliability & Efficiency in Switchgear Operations

Gapless form using zinc oxide (ZnO) particles for superior follow current interruption

Uses polymer housing with superior insulation and damage resistance

Combines the spark arrester and lead wire into one to secure straightforward constructability

Has no accessible charging section for the spark arrester and lead wire, thus preventing electrocution and bird accidents

Superior insulation secured by use of silicon-rubber insulated electrical wire

25.8 kV Polymer Insulated Cutout Switch

This product is attached to the primary side of a pole-mounted transformer on 22.9 kV-Y overhead power distribution lines. With the position of the extra-high-voltage polymer cutout switch used for transformer protection and switching, there is no danger of explosion due to insulation breakage.

Also, it is manufactured using a silicon housing structure with superior arc-suppression performance.
