Application
These capacitors are designed for use on DC supplies and are intended to protect the network from momentary voltage spikes and surges and for filtering out AC ripple.
Construction
The self-healing capacitor elements are enclosed in a cylindrical aluminium case, which is filled with a vegetable oil based gel (resin, solid matter) that is non-toxic, biodegradable, environmentally friendly. The case is fitted with an overpressure disconnector and an M12 mounting stud, which is also used for the protective conductor connection.
Application

Construction
The self-healing, dry-type, capacitor elements are produced using specially structured, seDC link capacitors - cylindrical cases
DC link capacitors - rectangular cases
gmented, metallised PP film which ensures low self-inductance, high rupture resistance and high reliability. These elements are enclosed in a rectangular steel case, which is filled with vegetable-oil based gel (resin, solid matter) that is non-toxic, biodegradable, environmentally friendly. Overpressure disconnector is not considered necessary. The capacitor top is sealed with self-extinguishing PU resin. The terminals design (arrangement) provides very low self-inductance.
