Dry-type reactor

Design

dry-type reactors are made without steel core, their voltampere characteristic is linear;
the reactor consists of a winding and a pressing system, which securely fixes the winding, the winding is wound on a dielectric frame;
wires with silicone insulation are used for winding, which corresponds to H class of heat resistance;
aluminum wire of rectangular cross-section consists of multiwire conductors (it is possible to use wire with insulated conductors, which will reduce losses during reactor operation);
pressing system consists of stainless steel tie rods and a system of glass-textolite strips;
silicone gaskets are used between wires and fiberglass plates to prevent damage to wire insulation.
