The JSZW-10G three-phase voltage transformer adopts a three-phase five column iron core. The primary and secondary coils are concentric cylindrical, equipped with three sets of secondary windings: a 0.2 level measuring coil, a 0.5 level monitoring coil, and an auxiliary coil (open triangle). The body of the transformer is made of epoxy resin, and the protective iron box and porcelain sleeve are installed outside to prevent direct sunlight and rainwater from soaking. Due to its oil-free nature, it can eliminate fire hazards and oil stains, operate safely and reliably, and can be maintenance free. It is the preferred product for small-scale substations.

Rated voltage: 3 kV, 6 kV, 10 kV;
The rated voltage ratio, insulation level, accuracy level, and corresponding rated secondary load are shown in the table:
