Power Switchgear

Main Features

Fully Integrated and Compact Design

Combines high-voltage intake, voltage transformation, low-voltage distribution, and protection systems into a single sealed enclosure, significantly saving space and eliminating the need for a separate substation building.

Factory-Prefabricated and Rapid Installation

Manufactured and tested as complete modular units in the factory, ensuring quality and enabling fast on-site deployment with minimal assembly time.

Highly Adaptable and Widely Applicable

Suitable for diverse scenarios including urban residential areas, commercial districts, office buildings, as well as industrial parks and factories, providing flexible and efficient power distribution solutions.

Power Switch is the core equipment in the power system that controls the on-off of electric current, isolates faults, and ensures the safety of the power grid. According to voltage levels, arc extinguishing media, and functions, it can be divided into various types, such as SF6 gas-insulated metal-enclosed switchgear, SF6 high-voltage circuit breakers, high/low voltage switch cabinets, high-voltage vacuum circuit breakers, high-voltage load switches, high-voltage contactors, etc.

We can provide the cost-effective solutions for the power switch based on your needs.

Power Switchgear refers to a pre-fabricated assembly of electrical devices designed to control, protect, and isolate electrical equipment in power generation, transmission, distribution, and industrial power systems. It serves as the “command and protection core” of power grids, integrating key components such as circuit breakers, disconnectors, load switches, fuses, current/voltage transformers, and protection relays into a sealed metal enclosure.

SF6 Gas-insulated Metal-enclosed Switchgear (GIS)

SF6 Gas-insulated Metal-enclosed Switchgear (GIS)

It is a high-voltage/extra-high-voltage (HV/EHV) power switching device that encapsulates all key switching components (circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, busbars) in a hermetically sealed metal enclosure filled with sulfur hexafluoride (SF6) gas as the insulation and arc-extinguishing medium.

Hybrid Gas-Insulated Switchgear (HGIS)

Hybrid Gas-Insulated Switchgear (HGIS)

It is an advanced high-voltage/extra-high-voltage (HV/EHV) switching device that integrates the advantages of Air-Insulated Switchgear (AIS) and Gas-Insulated Switchgear (GIS). It encapsulates core components requiring high insulation/arc-extinguishing performance (circuit breakers, disconnectors, earthing switches) in SF₆ gas-sealed metal enclosures, while exposing non-critical components (busbars, current transformers, voltage transformers) to air for insulation.

Gas-insulated Metal-enclosed Switchgear

Gas-insulated Metal-enclosed Switchgear

It is a high-voltage power switching device that encapsulates all key electrical components (circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, busbars, and cable terminations) in a hermetically sealed metal enclosure filled with gas (e.g.,dry air, nitrogen) as the primary insulation and arc-extinguishing medium.

Gas-insulated Metal-enclosed Switchgear

Gas-insulated Metal-enclosed Switchgear

It is a high-voltage power switching device that encapsulates all key electrical components (circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, busbars, and cable terminations) in a hermetically sealed metal enclosure filled with gas (e.g.,dry air, nitrogen) as the primary insulation and arc-extinguishing medium.

High-voltage Metal-enclosed Switchgear

High-voltage Metal-enclosed Switchgear

It refers to a modular High-voltage (LV) power switching device that that encapsulates key electrical components (circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, busbars) in a metal enclosure to ensure safety, insulation, and environmental protection (voltage rating typically ≥1kV).

Low-voltage Metal-enclosed Switchgear

Low-voltage Metal-enclosed Switchgear

It refers to a modular low-voltage (LV) power switching device that encapsulates key electrical components (circuit breakers, contactors, thermal overload relays, current transformers, busbars, and protection devices) in a metal enclosure (voltage rating typically ≤1kV).
