Inflatable high-voltage switchgear

An inflatable high-voltage switchgear is a fully insulated, fully enclosed high-voltage distribution device in which all live components—such as circuit breakers and disconnect switches—are sealed within a stainless-steel gas‑filled enclosure. Its functional units are independently modular, allowing for flexible configuration and expansion; configuration can be adjusted without the need to charge or vent gas, thereby meeting the requirements of distribution network automation. Through modular design and gas insulation technology, it achieves high reliability, compactness, and safety. Commonly used insulating media include SF6 gas or dry air.

Primary and Secondary Integration Standardized Ring Main Unit

The integrated primary‑secondary standardized ring main unit is a new type of intelligent distribution device designed in accordance with State Grid's standardization requirements. By achieving deep integration between primary equipment (circuit breakers) and secondary equipment (DTUs), along with a standardized interface design, it enables smart, modular, and highly reliable operation of distribution network equipment.

Standardized Center-Position Cabinet

The standardized center-mounted switchgear is an indoor, packaged distribution device used for receiving and distributing electrical energy, as well as for controlling, protecting, and monitoring circuits. Its standardization is essential for ensuring the safe, reliable, and efficient operation of power systems, while also enhancing equipment versatility, interchangeability, and ease of operation and maintenance. It is widely employed in the distribution systems of power plants, substations, industrial and mining enterprises, and large-scale buildings.
