Resin Rich Insulation System
( Up to 15 KV, confirmed)

The resin rich insulation system is F class insulation system for motors and generators up to 15 kV. It shows excellent electrical, thermal and mechanical properties and is able to resist severe environmental conditions. Prior to applying the main insulation, the straight parts of the coils are pre-pressed. After the insulation is comleted, the following tests are applied to all coils: Surge Test, AC Hi-POT Test, Tangent Delta MEasurment, Partial Discharge Test.

VPI Insulation System
( Up to 15 KV)

The VPI insulation system is for Vacuum Pressure Impregnation in class H (depending of the VPI resin) for motors and generators. The insulation materials from this system are compatible with most epoxy and polyester VPI resins. It is however always advisable to check the compatibility of the Softcoil-C system with the particular VPI resin. Dependent on the properties of the VPI resin, the Softcoil-C system can be used for motors and generators up to 15 kV. With an appropriate VPI process, the Softcoil-C system results in a high class winding with excellent dielectric and mechanical properties. Surge test is performed on all coil.

Thermoflex Insulation System
( Up to 6 KV)

The Thermoflex system is a hybrid class F insulation system for motors and generators up to 6 kV if no Tangent Delta and DLA measurements are required. The Thermoflex system offers the main advantages of both the resin rich coil (electrical, thermal and mechanical stability after curing without impregnation) and of the soft coil (flexible during winding and a continuous insulation). The Thermoflex coil combines an economical price with easy winding properties and an excellent quality level. Thermoflex insulation system is advised only up to 6 kV.

Green System
( Up to 1 KV)

In the green system, there is no insulation in the straight part. In some cases mecanical tape is used on straigt parts. Greesn system is advised u oto 1 kV.
