Main advantages

Step Lap Lamination

Excellent cold rolled grain-oriented silicon steel is used for core. The silicon steel is cut by automatic machine with high accuracy and small burr. Low no-load loss and current are achieved by the technology of pin-stacking and stacking without upper yoke. The structure can reduce the noise effectively.

 

LV foil winding

The standard low-voltage winding twine by copper foil (or aluminum foil) with interleaved DMD which bear less dielectric stress. The assembled coils are then oven-cured to form uniformly bonded solid cylinders that are anti-moisture. Such winding has excellent dynamic stability under shortcircuit condition.

 

Eco+POWER

No fire risk caused by flammable materials.

No risk of environmental contamination caused by liquid leakages.

Used materials are recyclable.

 

Savings

High efficiency design, reduced maintenance and installation flexibility in the buldings.

 

Compactness

Compact design for indoor and special room or box dimensions combining terminals position flexibility.

 

Resistance

Designed and tested for hard enviromental areas from contaminated zones to low temperatures installations.
