10kv High Voltage Switch Cabinet

KYN series high voltage switch cabinet is suitable for power receiving and distribution in 3.6-12Kv three-phase AC 50Hz single bus and single bus section system. It has the functions of controlling, protecting and monitoring circuits.

Conditions of Use

1. Ambient temperature: upper limit +40°C and lower limit -10°C;

2. The altitude does not exceed 1000 meters;

3. Air relative humidity: daily average ≤95%, monthly average ≤90%;

4. The seismic fissure does not exceed 8 degrees;

5. Places without conductive dust, corrosive gas and water vapor;

6. Where there is no fire, explosion hazard and severe vibration.

Note: ①When the above-mentioned normal use conditions are exceeded, the user can negotiate with our company to determine the allowable scope and technical measures.

②The electric heater should be switched on when the relative humidity is greater than 70%

③ Where the altitude exceeds 1000 meters, it shall be handled in accordance with the regulations of JB/Z102-72.
