The development trend of high voltage switchgear

(1) Domestic high voltage switchgear has been fully oil-free, and product upgrades represented by vacuum switches and SF6 circuit breakers have been realized.

(2) In order to meet the needs of the power industry for cross-grid operation, the development of UHV switchgear has entered the implementation stage.

(3) The miniaturization of metal-enclosed switchgear is an important direction of its technological development.

(4) The intelligent technology of high-voltage switchgear is developing rapidly.
