The FDGE8 semi-enclosed dry type discharge coil is cast in epoxy resin and semi-enclosed structured. The products are used for single-phase electric power systems of 50/60Hz rate d frequency and rated 12kV rated voltage, parallel connecting with high voltage capacitor group . The product can reduce the residual voltage of capacitor group to a safe voltage in 5 seconds after capacitor group is cut off from the electric system. When the coil is working normally, the secondary winding can act as voltage indicator. FDGE8 can be custom manufactured to combine residual winding for protecting relay purpose. The products are used for indoor mounting.
