Audited Supplier Overview
The device is mainly designed and manufactured for 10kV, 35kV, 110kV, 220kV cables, 110kV / 80000 kVA main transformer fully insulated, 110kV, 220kV GIS, switches and circuit breakers. The reactor adopts only separate designs, which can not only meet the requirements of high voltage and small current equipment test conditions, but also meet the requirements of low voltage AC voltage test such as 10kV cable. It has a wide range of application, and is the ideal high voltage test equipment of ground, city and county levels and power installation and repair engineering units.
Its is mainly composed of frequency conversion control power supply, excitation transformer, electric reactor and capacitor voltage divider.
