China Medium voltage switchgear guarantees Manufacturer, Supplier, Factory

The KYN28-12(Z) 7.2KV 1250A Commercial Switchgear Power Distribution Cabinet is designed for three-phase operating at a rated voltage of 12kV and a rated frequency of 50Hz. Its primary function is to manage the reception, distribution, and monitoring of electrical energy as well as to control and protect circuits.

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.

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.

The outdoor oil-immersed transformers at 10kV, 20kV, and 35kV levels have an advanced design with improved performance characteristics. They feature a unique structure with three core columns arranged in an equilateral triangle configuration. These gaps within the magnetic circuit, along with a core column loss, help reduce noise levels and ensure better balance of the transformer components. Additionally, these transformers effectively minimize the presence of the third harmonic component. They are suitable for various applications, including urban and rural areas, industrial and mining power grids, and are particularly well-suited for combination transformers and pre-installed substations.

The FZW28-12F 12KV Outdoor Demarcation Vacuum Load Break Switch LBS, as the boundary, is designed for outdoor installation on columns and can be operated manually or electrically. This switch utilizes the Corporation's VSP5-12 technology, making it a maintenance-free load switch. It uses vacuum arc extinguishing and SF6 gas for ground and phase insulation. This product conforms to the standards of GB3804 for high voltage AC load switch and GBT high voltage switchgear and control equipment.
