They are filled with vegetable oil, nitrogen or solid resin, most of them have their own safety mechanism, their capacitance ranges from a few micro- to several dozen millifarads.
Our AC capacitors with SecuMet™ metallization are famous for their durability and safe operation.
Install and forget.
In AC filters, capacitors face significant current and voltage stress. Optimized design minimizes power losses and the resulting thermal load, even in the Kilohertz range.
We have come up with a simple but effective – and very reliable – solution for high-voltage applications: even in the 50kV range, we can do without expensive ceramic insulators.
They are as different as they look: instead of the conventional oil, we fill solid resin into our surge capacitors.
