LV Winding Process

Wound from edge conditioned copper foil, the LV coil is manufactured to be in complete symmetry with the HV coil and completely centered on the limbs, thus exhibiting an excellent impulse and short circuit behavior.

Each layer of the LV coil is insulated by a resin pre-impregnated paper that will be heat activated to bond with the copper and thus form one very solid entity. The edge of the copper foil are also treated with care and protected by another special insulator that will be bonded along the copper during the polymerization process.

In all the polymerization process as will be described below will result in a very solid coil that will exhibit almost zero axial and radial forces due to short circuit conditions.

On the other hand the insulation process used and the subsequent polymerization procedure will result in a coil resistant to the most adverse and difficult industrial atmosphere.
