Service condition:

The height above the sea level is below 1000m.

Ambient temperature:

Highest air temperature +40ºC

Highest daily average air temperature +30ºC

Highest annual average air temperature+20v

Lowest outdoor air temperature-25ºC


The scope of application:

Applies to high fireproofing, load fluctuating, unventilated, incommodious, dirty and moist environment such as power plant field, subway, metallurgy, hospital, high-rise building, shipping center, crowded resident zone, and the special environment such as petrol-land chemical industry, nuclear power station, nuclear submarine.


Product features(advantages )of SGB10 Cast Resin Transformer:

A.Good heat emission, big overload capacity. Can work without wind machine for a long time under 130 overloads, and be full load without compulsive wind cool without capacity descending under IP45 condition.

B.Perfect safe and resistance to fire operating can be combusting for long period under 800ºC and without smoke

C.Strong resistance to thermal shock(can be full load immediately at -50ºC)

D.Complete waterproof and airproof.

E.No partial discharge

F. Good hydrophobicity and good resistance to alkaline cauterization and fundal influence

G. Environmental, low noise, no deleterious gas, easy to decomposition.

What is Non-Encapsulated Coil Dry-Type Transformer?

The Non-encapsulated coil dry-type transformer is characterized by safety,reliability,energy saving,fire protection,anti-explosion,simple maintenance,etc.The well-designed coil structure and vacuum impregnation treatment process makes the dry type transformer free of partial discharge and free of fracturing or insulation level decline during the whole shelf life.All products are qualified by National Mechanical & Industrial Bureau and National Power Company. It is widely used in power network, projects,grid construction,etc.
