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 72.5KV 1600amp Outdoor SF6 high-voltage tank circuit breaker is a unique electrical switch used to disrupt high-voltage electric circuits when faults occur or for regular switching tasks. It relies on sulfur hexafluoride (SF6) gas enclosed in a sealed tank to extinguish arcs and provide insulation. This particular circuit breaker is specially designed for outdoor placement in electrical substations and power distribution systems.

In recent years, with the continuous development of society, economy, and switch technology, the complexity of engineering construction has increased. 40.5KV 3150A Main Transformer Incoming Cabinet High Current High Voltage Switchgears that are miniaturized, maintenance-free, and intelligent for switch equipment are increasingly favored. Domestic and foreign switch manufacturing companies are vigorously developing medium voltage gas-filled cabinets (C-GIS), also known as gas-insulated switchgear. The so-called gas-insulated switchgear refers to sealing high-voltage components such as busbars, circuit breakers, isolating switches, power cables, etc.,inside a shell with lower gas pressure.

The GW5 outdoor isolation switch is a high-voltage electrical device designed to meet specific structural requirements. It consists of three independent single-phase isolation switches, making it a versatile and reliable option for various applications. The device complies with the standards outlined in the JB520-64 "AC High Voltage Isolation Switch" and features an additional grounding knife device for added safety. The CS-G manual operating mechanism is available in three variations: ungrounded, single-grounded, and double-grounded, providing users with options to suit their needs.

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.
