245kV Dry-type GIS Termination-High-voltage cable accessories catalogue-Products-Angelor (Jiangsu) Intelligent Electric co.,LTD.

Premolded stress cone with geometric design and uniform interfacial pressure from the spring compression system ensures effective electric field control and long-term reliability;
Sufficient electrical safety design;
Interface dimensions fully comply with the latest IEC and GB standards;
Dry-type, fully sealed top design for easy installation and elimination of gas leakage risk.
The epoxy insulator (GIS plug-in part) can be pre-installed in the GIS enclosure (with sealing insert or sealing plate) before ship to the site, allowing factory electrical testing together with the GIS equipment;
Extension rod design allows flexible configuration between short-type and long-type terminations;
Proven design with extensive service experience, ensuring high operational reliability.
