Environmental protection dry type power transformer
Work condition
Altitude: not exceed 1000m;
Supply voltage waveform: similar to a sine wave;
Symmetry multiphase power supply voltage: polyphase transformer connected supply voltage should be approximately symmetrical.
Ambient temperature: Maximum temperature + 40℃；the highest daily average temperature +30 ℃ ; The highest annual average temperature is + 20 ℃ ； minimum temperature of -30 ℃ （suitable for indoor type transformer）
Structure
High standards of safety, Non-flammable resin, no toxic gas, no combustion;
Reduction in volume and weight per KVA;
Increase the capacity of the emergency overload;
Repair, easy to maintain;
Low noise;
Humidity, insensitive to dust, pollution;
Running without partial discharge and without the possibility of "cracking";
Design flexibility, customers can request the design of any specification made need.
