Inflatable high-voltage switchgear

An inflatable high-voltage switchgear is a fully insulated, fully enclosed high-voltage distribution device. All live components, such as circuit breakers and disconnect switches, are sealed within a stainless-steel gas enclosure. Its functional units are independently modularized, supporting flexible configuration and expansion; configuration can be adjusted without the need for inflation or deflation, 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 Integrated 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 to receive and distribute electrical power while providing circuit control, protection, and monitoring. Its standardization is essential for ensuring the safe, reliable, and efficient operation of power systems, as well as for 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.
