The 35kV 35KV PV Pad mounted Transformer is a combination transformer used for wind or photovoltaic power generation, which integrates a step-up transformer, high-voltage current limiting fuse, load switch, low-voltage switchgear, and corresponding auxiliary equipment. The capacity range is 500-6800KVA, and the voltage level is 35kV and below. It is suitable for various types of onshore, pond, and offshore photovoltaic and wind power plants.

The DZ47-63 series miniature circuit breaker is designed for use in lighting and motor distribution systems, protecting against overloads and short circuits. Its innovative design, lightweight construction, and dependable operation make it a high-performance solution.

The ZW32 series 12kv 630A Outdoor Pole Mounted Vacuum Circuit Breaker VCB is a reliable distribution device designed for outdoor use in harsh weather conditions. With a rated voltage of 12kV and a three-phase alternating current of 50Hz, it is suitable for a variety of applications, including substations, industrial and mining enterprises, and rural power grids that require frequent operation. The circuit breaker's compact size, lightweight, and resistance to condensation make it easy to maintain and operate. It can handle load currents, overload currents, and short circuit currents, ensuring a dependable performance in power distribution and control.

The Drawer type low-voltage switchgear ensures that each functional unit is distinct from the busbar or cable, creating three separate areas for efficient power distribution. This design also incorporates isolation measures between functional units, contributing to the overall reliability and safety of the switchgear. As a result, drawer-type switchgear is widely used in industrial and mining enterprises, high-rise buildings, and centralized control distribution centers that require high power supply reliability. The switchgear's closed steel plate shell houses withdrawable drawers containing electrical components for incoming and outgoing circuits, allowing for easy maintenance and customization.

In recent years, the field of engineering construction has faced increasing complexity due to advancements in technology and the growth of society and the economy. There is a rising demand for compact switch equipment that is smart and requires minimal maintenance. Both local and global manufacturers of switches are currently focusing on the development of 12KV 2500A Sf6 Sulfur Hexafluoride Infiilled Electrical Switchgear, also referred to as gas-insulated switchgear (C-GIS). These C-GIS systems encase high-voltage components like busbars, circuit breakers, isolating switches, and power cables in a housing with reduced gas pressure.

HXGN-12 switchgear Modular AC metal enclosed Ring main unit RMU is a high-voltage AC complete set designed for a three-phase AC ring network, terminal distribution network, and industrial electrical equipment. It is suitable for power distribution and protection and can be installed in substations. It complies with national standards GB3906 and IEC60298, as well as DL/T402 and DL/T404 standards, and meets the requirements of "five-proof" blocking.
