Environmental protection dry type distribution 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.
