2. Humidity: Daily average ≤ 95%, daily average of water vapor pressure ≤2.2Kpa;
                    Monthly average ≤90%, Monthly average of water vapor pressure ≤1.8Kpa;
3. Altitude:  ≤1000m;
4. Earthquake intensity:  ≤magnitude 8;
5. Applicable in the places without corrosive, flammable gas and water vapor.
6. Used in place without frequently intense vibrant.

Features
The enclosure is completely assembled from aluminised and galvanised steel plate, which are machined and bent by machine tool and then bolted.
It has high mechanical strength and its neatness and beauty is ensured.
The switchboard door is sprayed with plastic, also has strong capacity of impact resistance and corrosion protection.
The protection grade of the enclosure is of IP4X.
The primary switch may be provided with VD4 vacuum circuit breaker and C3 series of fixed type load switch from ABB, various domestic vacuum circuit breakers (such as VS1, VH1, VK, ZN28) may also be provided in lieu of the same foreign products.
