Cast Resin Dry Type Power Transformer

Features of Dry Type Transformer

1. High safety: dry-type transformer has no combustible resin, does not support combustion during use, can be flame retardant, does not explode and release toxic gases, does not cause harm to the environment, other equipment and human body, and is not sensitive to humidity, dust and pollution. There is no possibility of partial discharge and "cracking" during operation.
2. High reliability: NOMEX insulation material is selected for high and low voltage coils, and Class H solvent-free impregnating paint is impregnated by VPI vacuum pressurizing equipment for many times, and the coils are baked and cured at high temperature for many times. The product is Class H (180 ℃), while the main insulation material is Class C (220 ℃), with strong overload capacity and good short-circuit resistance. Under the condition of good ventilation, 20% overload operation is allowed.

3. Energy conservation and environmental protection: steel, iron and other materials are easy to recover after the end of product life; All NOMEX paper used will not release toxic substances when burning; Other insulating materials can be degraded without polluting the environment; Low loss and energy saving of products; Low noise, flexible design.


Because dry-type transformer has no oil, there is no fire, explosion, pollution and other problems, so electrical codes and regulations do not require dry-type transformer to be placed in a separate room. The loss and noise have been reduced to a new level, creating conditions for the transformer and low-voltage panel to be placed in the same distribution room.
