Combined transformer products are composed of casting body (housing), secondary outlet box (including secondary wiring terminals), installation board and other parts.

Combined transformer in V/V wiring mode, its A and C phases are connected in series with current transformers respectively, and the voltage part is connected in V/V mode. This transformer is suitable for three-phase three-wire meter measurement.

Combined transformer in Y/yo wiring mode, its A, B and C phases are connected in series with current transformers respectively, and the voltage part is connected in Y/yo mode. This transformer is suitable for three-phase four-wire meter measurement.

The product is epoxy resin casting insulation, single-phase, busbar type inductive voltage transformer. The body is provided with grounding bolts and marked with a grounding plate. The body and the epoxy resin mixture are integrally cast, and the secondary terminals are directly led out from the cast body. The body is cast in one piece with epoxy resin, which has good anti-seismic effect and high mechanical strength.
