Advantages & Features

132/220/550kv GIS is modular design. The live part of the product is completely sealed in the metal shell and insulated by SF6 gas, which prevents the invasion of foreign matters outside, and ensures the good insulation performance of the product.
Due to modular design, the design and installation are flexible, which greatly meet the requirements of customers;
The product is small in volume and light in weight;
Compact structure, space saving;
The whole transportation is convenient for installation;
The opening ability is strong and the insulation level is high;
Product safety, reliability, stable operation.

Working Principle

SF6 gas is used as the insulating medium, and the main circuit conductor is enclosed in the gas chamber by the grounded metal shell, including the electrical function modules such as circuit breaker, isolation (grounding) switch, current transformer, voltage transformer, main bus line, incoming and outgoing bushing; Each combination is equipped with a local control cabinet, which configures various monitoring and secondary control components in the cabinet. The action of each element in GIS equipment is controlled by the principle of relay protection, realizing the function of interlocking locking, meeting the requirements of system eliminating fault and switching power load.
