China miniature relay 12v Manufacturer, Supplier, Factory

The 12KV 2500A High Current Customized Electrical Switchgear KYN28-12(Z) AC metal-clad switchgear is designed for 12kV three-phase AC power systems operating at a frequency of 50Hz. Its primary function is to manage the flow of electricity by receiving, distributing, and overseeing circuits while providing control and protection.

This product is designed for 50Hz AC power distribution networks with a rated operational voltage of 380V and a rated current up to 630A. It provides reliable indirect contact protection for personnel and effectively prevents fire hazards caused by ground fault currents resulting from equipment insulation failures. The device incorporates multiple protection mechanisms to deliver precise overload and short-circuit protection for power distribution lines and supply equipment, while featuring circuit status monitoring capabilities. Under normal operating conditions, it can serve as an infrequent switching device for distribution circuits and provide occasional motor starting control functionality. The integrated design combines electrical safety protection with equipment management requirements, significantly enhancing the operational reliability of power distribution systems and fire prevention capabilities.

The GGD-type Low voltage AC distribution switchgear is a versatile and reliable solution for various power distribution needs. It is well-suited for AC 50Hz distribution systems with a rated working voltage of 380V and a maximum current rating of 6300A, making it a great choice for power plants, substations, mining operations, and other heavy-duty power users. This distribution cabinet is designed with a focus on safety, efficiency, and adaptability, offering a range of features such as high breaking capacity, strong stability, flexible electrical configurations, convenient combination options, and a practical and novel structure. Additionally, it offers a high level of protection, making it an ideal replacement for low-voltage switchgear sets.

In recent years, engineering construction has become increasingly intricate due to the growth of society, the economy, and technology. There is a rising trend towards smaller, smarter switch equipment that demands minimal maintenance. Manufacturers, both local and global, are focusing on the development of the 40.5kv 2000A High Voltage Sf6 Gas Insulated Switchgear, also referred to as gas-insulated switchgear (C-GIS). These switchgears house high-voltage elements like busbars, circuit breakers, isolating switches, and power cables within a protective shell with reduced gas pressure.

40.5KV 4000A Double-break three post disconnector is designed to enhance the efficiency of indoor stations by reducing the distance and station arrangement. Its robust motor performance resistance is achieved through the electric rod's self-rotation and switching structure, along with its self-locking function. This disconnector is capable of withstanding motor, wind pressure, earthquake, and other external forces. Additionally, its sliding rotation method ensures a strong self-clean ability.

The DZ20 series plastic shell circuit breaker (hereinafter referred to as the circuit breaker) is suitable for distribution lines with AC 50Hz, rated current up to 1250A, rated insulation voltage of 660V, rated working voltage of 380V (400V) and below, as overload, short circuit and undervoltage protection for distributed electrical energy, lines and power equipment. Among them, the Y, J, and G type circuit breakers with rated currents of 225A and Y type 400A can also be used to protect motors. Under normal circumstances, the circuit breaker can be used for infrequent switching of lines and infrequent starting of motors. The product meets the standards of JB8589, GB14048.2, and IEC947-2.
