The KYN28-12(Z) AC metal armored switchgear 11KV 630A Medium Voltage Indoor Electrical Switchgear is designed for three-phase AC power systems with a rated voltage of 12kV and a rated frequency of 50Hz. It serves as a reliable and efficient solution for receiving, distributing, controlling, protecting, and monitoring electrical energy in various applications.

The KYN28-12(Z) AC metal-clad switchgear 7.2KV 2500A High Current Electrical Switchgear is designed for use in 12kV-rated three-phase AC power systems operating at a frequency of 50Hz. It is utilized for the reception, distribution, and monitoring of electrical energy, as well as for circuit control and protection.

This American type prefabricated substation is developed by absorbing the latest advanced technology from abroad and combining it with the actual situation in China. The entire product has the characteristics of small size, easy installation and maintenance, low noise, low loss anti-theft, strong overload capacity, and full protection. Suitable for newly built residential green belts, parks, stations, hotels, construction sites, airports, and other places.

In recent years, with the growth of society and advancements in technology, engineering construction has become increasingly intricate. There is a rising demand for compact switch equipment that is easier to maintain and features intelligent functions. Manufacturers of switchgear, both locally and internationally, are focusing on developing 12KV 2000A High Current Gas Insulated Electrical Switchgear, which are also referred to as gas-insulated switchgear (C-GIS). These switchgear units house high-voltage elements like busbars, circuit breakers, isolating switches, and power cables within a shell that operates at reduced gas pressure.

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.

The CFB3 series miniature circuit breaker is suitable for overload and short circuit protection in AC 50/60Hz, rated voltage up to 230V/400V, and rated current up to 125A lines. It can also be used for infrequent on/off operations of the line under normal conditions. The CFB3-63 series circuit breaker is equipped with accessories such as CFB3-F auxiliary contacts, CFB3-FB auxiliary alarm contacts, CFB3-FL shunt release, CFB3-QY undervoltage release, CFB3-GY overvoltage release, CFB3-GQY overvoltage release, etc., providing convenience for the intelligent control of smart buildings. Overvoltage, undervoltage, and overvoltage/undervoltage are electronic release devices that are assembled and combined with circuit breakers or residual current circuit breakers. They are suitable for AC 50Hz/60Hz circuits with a rated voltage of 230V, and are used to protect against overvoltage, undervoltage, and overvoltage caused by line faults, avoiding damage to electrical equipment or inability to function properly due to fluctuations in grid voltage. The circuit breaker has an isolation function. Compliant with standards: GB/T10963.1, IEC60898-1, GB/T20645.
