Asset VCB series patented capacitors are totally dry units with no impregnation or insulation liquid.
They are designed by assembling individual single-phase coils, coupled in a delta arrangement to obtain a three-phase unit.
The coils are produced from two films of polypropylene with zinc plating on one side:
- The metal plating forms the electrode.
- The polypropylene film forms the insulator. All coils are then coated under vacuum into self-extinguishing thermoset polyurethane resin which forms the casing, providing mechanical and electrical protections.
Unique vacuum potting technique ensures that Asset VCB series capacitors have excellent resistance over time and much longer service life than conventional units.
