Enclosed Switchgear
MV NEXCustomization
MVnexHP 12kV armored withdrawable metal-enclosed switchgear (hereinafter referred to as switchgear) is a brand-new product developed by our company in collaboration with Schneider Electric, authorized, approved and monitored by Schneider Electric, and released with a label after passing the inspection. It is applied in 12kV medium-voltage systems and meets the standards of GB11022, GB3906, GB1984, DL/T593, DL/404, DL/402, etc. It is equipped with the "five-prevention" function. This product is based on the business model of technical cooperation and authorization from Schneider Electric. It adopts a brand-new structural design and higher-performance core components, featuring a higher safety level and electrical performance, and can better meet the needs and usage habits of Chinese users. MVnexHP medium-voltage switchgear can be widely used in commercial buildings such as hotels, hospitals, and office buildings, as well as residential buildings, infrastructure such as telecommunications airports, and rail transit, and light industrial projects such as electronics, food, and papermaking.

Usage environment
1. Ambient air temperature:
Upper limit: +40 °C, the temperature should not be lower than -15 °C (with a 24 - hour average temperature of +35 °C).
2. Altitude:
The altitude should not exceed 1000 m. In the case of higher altitudes, the rated insulation level should be increased accordingly.
3. Relative humidity:
The daily average relative humidity should not exceed 95%, and the monthly average should not exceed 90%.
4. Installation environment:
The equipment should be installed in an environment free from flammable and explosive risks, severe fouling, chemical corrosion, and intense vibration.
Special operating conditions:
1. Rising ambient temperature:
(1) The current-carrying capacity will decrease.
(2) To enhance heat dissipation, auxiliary cooling equipment needs to be provided.
2. Climatic factors:
(1) Appropriate measures should be adopted to prevent the formation of condensation.
(2) The risks of corrosion and other forms of damage should be avoided.
