    Application areas:

    For use with gas-insulated metal-enclosed switchgear (GIS or C-GIS), suitable for voltage levels of 52kV and below.

    Product Description

    1. Dimensions conform to EN-50181 design requirements; product performance meets GB/T12706.4 standard requirements. 2. Insert-type installation inside enclosed equipment allows for plugging and unplugging during maintenance. 3. Fittings feature a dual-strap contact finger design to meet greater current capacity requirements.

    4. The insulating body is made of high-quality imported liquid silicone as the base material and is molded by high temperature and high pressure injection process. The product has excellent properties such as high elasticity, high tear resistance, aging resistance, corona resistance and creepage resistance; the structural design is optimized and the installation process is excellent.
