Introduction of Low Voltage Switchgear GGD

Some structural features of Low Voltage Switchgear GGD:

  1. The cabinet body of the GGD distribution cabinet adopts a universal cabinet design, with the frame constructed from 8MF cold-formed steel that is partially welded and assembled. The frame components and specialized supporting parts are produced and supplied by our company to ensure the precision and quality of the cabinet body.
  2. The design of the low voltage switchgear GGD fully takes into account the heat dissipation issues during operation. There are varying numbers of ventilation slots at both the upper and lower ends of the cabinet. When the electrical components inside the cabinet generate heat, the warm air rises and is expelled through the upper ventilation slots, while cool air continuously enters the cabinet through the lower slots. This creates a natural ventilation pathway from the bottom to the top of the sealed cabinet, effectively achieving heat dissipation.
  3. The cabinet doors are connected to the frame using pivot-type hinges, allowing for easy installation and removal.
  4. The surface of the cabinet body is treated using a high-pressure electrostatic powder coating process. This method enhances the durability and aesthetic appeal of the cabinet, providing a smooth and attractive finish while ensuring strong adhesion and resistance to wear and corrosion.

Introduction of Low Voltage Switchgear GCK

Some structural features of Low Voltage Switchgear GCK:

  • GCK’s basic cabinet frame is designed as a modular assembly structure. The frame is made of hot-rolled steel (STHC), and the FA profiles are positioned using angle plates and connected with bolts, resulting in a non-welded structure. The forming dimensions, hole sizes, and equipment clearances of the components are standardized to modular dimensions.
  • The internal structural components are treated with galvanization.
  • The external structural components are treated with acid pickling and phosphating, followed by high-pressure electrostatic spraying.
  • The structural components have strong versatility and high mechanical strength.
  • The upper part of the cabinet is the main busbar chamber, the front part is the electrical chamber, and the rear part is the cable entry and exit chamber. Steel plates or insulating boards are used for isolation between the chambers to ensure safe operation.

Introduction of Low Voltage Switchgear GCS

The low voltage switchgear GCS is suitable for distribution systems in industries such as power plants, petroleum, chemical, metallurgy, textiles, and high-rise buildings. In places with high levels of automation, such as large power plants and petrochemical systems, where interfaces with computers are required, it serves as a low-voltage complete distribution device for power generation and supply systems. It operates at a three-phase alternating current frequency of 50 (60) Hz, with a rated working voltage of 380V (400V) or 660V, and a rated current of 4000A and below, used for distribution, centralized motor control, and reactive power compensation.

  • The main frame assembly design is available in two forms: a fully assembled structure and a partially welded structure (side cabinets and cross beams), allowing users to choose according to their needs.
  • The various functional compartments of the assembly are isolated from each other. These compartments are divided into functional unit rooms, busbar rooms, and cable rooms, with each room serving an independent function.
  • The horizontal main busbars are arranged in a flat configuration at the rear of the cabinet to enhance the busbar’s ability to withstand electrodynamic forces. This is a fundamental measure to ensure that the main circuit of the device has a high short-circuit breaking capacity.

High and Low Voltage Switchgear XGN2-12

  • Ambient temperature: High temperature 45°C, low temperature -35°C
  • Daily temperature difference: No more than 25°C
  • Earthquake tolerance: Earthquake intensity does not exceed 8°C

The XGN2-12 switchgear features a metal-enclosed box structure. The cabinet frame was originally designed to be welded from angle steel, but after development by our company, it can also be constructed using bent steel plates. This not only greatly enhances the aesthetic appearance but also facilitates production organization and shortens the production cycle. The cabinet is divided into compartments for the circuit breaker, busbar, cable, and relay, with steel plates separating each compartment.

Introduction of High and Low Voltage Switchgear XGN2-12

The XGN2-12 box-type fixed metal-enclosed switchgear is used in three-phase AC systems with a voltage of 12kV and below, operating at a frequency of 50Hz, for the purpose of receiving and distributing electrical energy. It is particularly suitable for applications that require frequent operation. The busbar system consists of a single busbar (which can also be configured as a single busbar with a bypass or a double busbar structure).

Some structural features of High and Low Voltage Switchgear XGN2-12:

  • The circuit breaker chamber is located at the lower front part of the cabinet. The rotation of the circuit breaker is connected to the operating mechanism via a pull rod. The upper terminal of the circuit breaker is connected to the upper isolating switch, while the lower terminal is connected to the current transformer. The current transformer is connected to the busbar of the lower isolating switch. Additionally, the circuit breaker chamber is equipped with a pressure relief channel, allowing gas to be released through the exhaust channel in the event of an internal arc.
  • The busbar chamber is located at the upper rear part of the cabinet. To reduce the height of the cabinet, the busbars are arranged in a U-shape and supported by porcelain insulators with a bending strength of 7350N. The busbars are connected to the busbar of the upper isolating switch, and isolation is possible between adjacent busbar chambers.
  • The cable chamber is located at the lower rear part of the cabinet. Insulators in the cable chamber may be equipped with voltage monitoring devices, and the cables are secured to the brackets. When the main wiring is configured as a connection scheme, this chamber serves as a connection sub-chamber. The relay chamber is situated at the upper front part of the cabinet, where mounting plates can accommodate various relays and other devices. There are terminal block supports inside, and the door can be fitted with indicating instruments, signal elements, and other secondary components. Additionally, a secondary small busbar can be arranged at the top.
