resin insulated dry-type power transformer

product overview 

mns low-voltage complete switch equipment is my company according to the market need to introduce the development of a new generation of low-voltage switchgear. product technical standards it "low-voltage complete switch equipment and control equipment"; gb7251 "low-voltage complete switch equipment" and other standards. 

scope of application 

mns type low voltage draw-out type switchgear cabinet is suitable for power plants, substation, petrochemical industry, metallurgy, steel rolling and other industrial enterprises and residential area, high-rise buildings and other places, as ac 50 to 60 hz, the rated working voltage of ac 660 v and below the power distribution system of the transformation and energy consumption equipment control. 

using the environment condition 

ambient air temperature is not higher than 40 ℃, no less than 5 ℃, and its average temperature is not higher than within 24 h 35 ℃. 

atmospheric conditions, clean air, the relative humidity in 40 ℃ less than 50%, the highest temperature at lower temperature to allow a higher relative humidity, such as at 20 ℃ at 90%, but given the due to temperature changes, occasionally produce a moderate amount of condensation. 

no more than 2000 m above sea-level. 

this device adapted to the following temperature process of transportation and storage: 25 ℃ to 55 ℃ range between, in a short period of time (not more than 24 h) can be up to 70 ℃, under the limit temperature devices should avoid any unrecoverable damage and should be able to work under normal conditions. 

if the above conditions of use can't meet, shall be settled by users and manufacturers to negotiate. 

when this device used at sea oil drilling platform, and nuclear power plants should be separately signed the technical agreement.
