High and low voltage switchgear

At the moment when industrial automation and modern power systems are developing rapidly, high and low voltage switchgear is no longer a simple power device. It is like a precise "power valve", a key node of the power network, and directly defends the stability and safety of the power system operation. Our company has been deeply involved in this field for many years and has formed a unique technical accumulation. From the early basic models to today's intelligent products, every step of growth is due to the persistent pursuit of the essence of technology.

As a key equipment in the power system, high and low voltage switchgear mainly carries the following core functions:

First, power distribution and control. Including as a power transmission hub, it is responsible for transmitting power from the power generation end to the power consumption end in power plants, substations and distribution systems to achieve a reasonable distribution of power; through built-in circuit breakers, disconnectors and other equipment to achieve circuit on-off control to meet different power needs.

Second, power system protection. It can quickly cut off the faulty circuit when the circuit is short-circuited, overloaded or other abnormal conditions occur, preventing the accident from expanding; at the same time, it protects important power equipment such as generators and transformers from damage.

Third, power regulation. The switch cabinet can be equipped with a capacitor compensation device to improve the power factor to improve the voltage quality, reduce the power loss of the power grid, and enhance the power supply capacity of the equipment.

There are various types of high and low voltage switchgear (please check the product details page for the specific information of the following types of switchgear):

High voltage switchgear (air insulated type), such as KYN28A-12/24 voltage level 12/24kV, metal armored removable structure, four-chamber separation, central trolley design and support for quick replacement of circuit breakers, and complete five-protection interlocking function; KYN61-40.5 voltage level 40.5kV, floor-standing trolley structure, suitable for domestic ZN85 or imported VD4 circuit breakers, modular assembly, mechanical life ≥10,000 times, suitable for high altitude areas and frequent operation scenarios; XGN15-12 voltage level 12kV, compact fixed design, suitable for limited space, using epoxy casting process, support multi-cable parallel connection and PT expansion; HXGN17-12 voltage level 12kV, ring network cabinet structure, small size, support FN12 and FZN25 load switches, maintenance-free design, protection level IP3X, in line with the "five protection" requirements.

High-voltage switchgear (SF6 gas-insulated type), such as SRM□-12/24 voltage level 12/24kV, fully sealed gas-filled cabinet, stainless steel gas tank, protection level IP67, salt spray/condensation resistance, modular combination, support for flexible expansion of incoming lines, metering, and PT cabinets; SRM6-40.5 voltage level 40.5kV, double-sealed structure, equipped with fast grounding switch, passed 185kV lightning impulse test.

Low-voltage switchgear (AC 690V and below), such as GCS drawer type, module E=20mm, drawer unit supports flexible combination, horizontal busbar is rear-mounted, vertical busbar has flame-retardant function board, and has strong intelligent expansion capability; GCK drawer type, module E=25mm, drawer unit supports flexible combination, vertical busbar has no partition, low cost but weak heat dissipation, suitable for simple power distribution needs; MNS drawer + fixed hybrid, C-shaped steel frame, module E=25mm, drawer unit supports a variety of flexible combinations, supports intelligent monitoring module integration; GGD fixed type, with economical and practical, flexible line scheme, convenient combination, strong practicality, simple structure and easy maintenance.
