Environment-friendly inflatable ring network cabinet is based on the advanced production, manufacturing and inspection of the original SF6 gas insulated ring network cabinet. It is a new generation of high-tech, energy-saving, clean and environmentally friendly switch equipment developed by low-pressure N2 completely replacing SF6 gas. Changing the user's operation and maintenance habits can provide users with a new, intelligent, efficient and green experience.
The box adopts laser welding sealing technology and vacuum helium leak detection, which has strong environmental adaptability
Gas tank is filled with slightly positive pressure N2 to prevent moisture intrusion from affecting the gas tank insulation
Under the condition of zero gauge pressure, it can ensure the product's safe and reliable operation and high power supply quality.
No toxic and harmful substances to the human and environment are generated during the operation of the equipment
No need to recycle gas after product reaches its life cycle
The equipment adopts environmentally friendly insulation materials, and the recycling rate of materials reaches 90% -95%
ZW32-12 / T type outdoor pole vacuum circuit breaker is outdoor power distribution equipment with rated voltage of 12kV and three-phase AC 50Hz. The circuit breaker uses a spring operating mechanism, which is mainly used to open and close the load current, overload current and short circuit current in the power system.
