RNZH air-insulated compact switchgear is the latest generation of 10kV high-voltage switchgear products independently developed and designed by RENLE Europe GmbH. Products are widely used in industrial and mining enterprises, high-rise buildings, residential quarters, schools, etc. as ring network power supply and terminal power distribution for 7.2kV and 12kV power distribution systems.
1. The biggest advantage of this product is that it uses air insulation, which is reliable and environmentally friendly. Its perfect performance and flexible assembly can meet the changing requirements of the market.
2. The cabinet is small in size and compact in structure. It is especially suitable for application places with limited space, and can relieve the current situation of tight land use in modern cities. The standard size of the cabinet is 450×1000×1800mm (width×depth×height)
3. The main switch adopts RNV1-12 high-voltage integrated vacuum circuit breaker, with isolation switch, current transformer, grounding knife, sensor, modular design and assembly, reliable interlocking and convenient maintenance.
4. The switch cabinet design clearly shows the isolation fracture. Open the secondary instrument room and observe the opening and closing positions of the isolation switch through the observation window.
5. The designed rated current of this complete set of device is 630A and 1250A, and the designed short-circuit breaking current is 25kA and 31.5kA.
6. The vacuum interrupter adopts a solid sealing method to completely separate it from the surrounding air. Increase the reliability of insulation.
7. The switch cabinet and main switch adopt modular design, which greatly shortens the assembly time of the factory and speeds up the delivery time.
