TMNS(MNS)LV extraction type switchgear

TMNS LV extraction type switchgear is a new generation type of LV swithgear according to the demand of the market. The cabinet applies standard modula design of compacted structure, and the framework of the cabinet formed by the C-type material and the inter isolation layer are all galvanied purification, and thus has the features of strong anti-corrosion, and each unit can be interexchanged and higher reliablity of power supply. TMNS LV extraction type switchgear is suitable for power plant, substaions, petrochemical, Hetai Gold rolling, light textile factories, mines, and other enterprises, residential quarters, skyscrapers and other places as the distribution equipment of AC 50 (60) Hz, 660V or down to rated working voltage to transfer, distribute and control the power.

1.The cabinet applies standard modula design of compacted structure, and the framework of the cabinet formed by the C-type material
2.the framework and inter isolation layer are all galvanied purification
3. strong anti-corrosion, and each unit can be interexchanged and higher reliablity of power supply

1、 max ambient air temperature is +40℃, and the min temperature is -5℃, the max daily average temperature is +35℃
2、 the relative humidity under the max temperature is no more than 50%, and the higher relative humidity is permittable when under the low temperature conditions. For example, when the temperature is +20℃ the humididty can be 90%. the moist effect should also be considerate for the temperature changes.
3、 the top altitude is 2000M.
4、 switchgear can be transported and stored under the following conditions, -25℃ to +55℃, within a short period time (no more than 24 hours) and no higher than +70℃，the transformer should not have any irreparable damage under such limittemperatures and can normally worked under the normal use conditions.
5、 the user should consulate with the manufacture if the use conditions are beyongd the above.
6、 the technology agreement should be sign if the equipment is used on the project of offshore oil and nuclear power plant.

it is suitable for power plant, substaions, petrochemical, Hetai Gold rolling, light textile factories, mines, and other enterprises, residential quarters, skyscrapers and other places
