As a well-known manufacturer of High Voltage Ring Net Cabinet in China, Kexun's HXGN(H)□ -12 series products have the characteristics of simple structure, flexible operation, reliable interlocking and convenient installation, and can provide satisfactory technical solutions for different applications and different users.
Model:HXGN(H)□ -12
Brand:KEXR
The High Voltage Ring Net Cabinet made by Kexun adopts advanced sensing technology, information technology and simple and flexible configuration scheme to meet the ever-changing market demand and also meet the requirements of power grid intelligence.
The HXGN(H)□-12 type High Voltage Ring Net Cabinet is suitable for industrial and civil cable ring networks and distribution network terminal projects. As the acceptance and distribution of electric energy, it is especially suitable for power distribution in urban residential areas, small secondary substations, switching stations, cable branch box, box-type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, stadiums, railways, tunnels and other places.
HXGN(H)□-12 meets the requirements of relevant national standards, electric power industry standards, international standards and other standards. Its switches and main electrical components are integrated modules, and the conductive parts between phases are encapsulated by solid insulation. Shielded cable connectors are used for external wiring, and shielded insulated buses are used for connecting buses of functional units. Therefore, the use safety is greatly improved. At the same time, its operating mechanism adopts spring mechanism, and its mechanical life is more than 10000 times. All operating data and equipment status can be monitored remotely and unattended. It is a superior power distribution device.
The following units can be selected in the cabinet to form an economical and practical power supply unit: vacuum circuit breaker unit (630A, 20-25ka); Vacuum load switch unit (630, 20-25kA).
