| Model NO. | 220 kV GIS cable terminal/transformer terminal (620 structure) |
| Rated voltage | 220kV |
| Series | YJZGG |
Product Features
·Adopting a plug-in fully sealed structure, silver plated contacts are used to connect the conductor and fittings
·The main body of the terminal stress cone is made of imported liquid silicone rubber, which has excellent electrical and mechanical properties
·The terminal is a dry structure without any filling fluid, which eliminates problems such as oil leakage and seepage
·Adopting a stress cone compression structure, the stress cone is tightly supported on the inner wall of the epoxy sleeve by a spring-loaded compression device, ensuring that the interface pressure does not change and guaranteeing the product's service life
·Reasonable product structure design, small size, and light weight
·Thoroughly solve the problem of top closure, and install quickly and conveniently
Short plug-in terminals used to connect gas insulated metal enclosed switchgear (GIS) with cables, transformers with cables, where "620 structure" is the core specification identification, representing a critical length dimension of 620mm for the terminal. It is an important accessory in high-voltage power systems to ensure reliable connection between cables and core equipment
