The FDGE9-1W fully enclosed outdoor dry discharge coil is an epoxy resin vacuum cast single-phase outdoor fully enclosed product, suitable for power systems with a rated frequency of 50 Hz and a rated voltage of 10kV and below. Connect in parallel with the high-voltage parallel capacitor bank, and when the capacitor bank is disconnected from the system, reduce the remaining voltage on the capacitor bank to a safe voltage within 5 seconds. During normal operation, the secondary winding can serve as a voltage indicator. If the user has special requirements, the residual voltage winding can also be included to provide relay protection.



Structural characteristics:
This type of discharge coil adopts a fully sealed structure with resin cast insulation for the iron core. The iron core is made of high-quality cold-rolled steel sheets and is cast together with the primary and secondary windings using advanced vacuum casting technology. It is an ideal product to replace oil immersed discharge coils due to its small size, light weight, small no-load capacity, strong overvoltage resistance, easy installation and use, and maintenance free.
