The utility model relates to dual supports for a voltage transformer. First U-type main supporting steel channels and second U-type main supporting steel channels are respectively vertically arranged at the two ends of U-type connecting channel steel to form a Z-shaped frame, and a reinforcing rib is arranged between the second U-type main supporting channel steel and the U-type connecting channel steel; and two Z-shaped frames are arranged in parallel and are connected via installation flat plates which are arranged on upper surfaces of the two first U-type main supporting steel channels and the two second U-type main supporting steel channels. The dual supports for the voltage transformer have the advantages that the voltage transformer is integrated with a breaker, and the voltage transformer and the breaker are mounted in one time, thereby effectively reducing the workload and unnecessary installation troubles, requiring no additional installation support for the voltage transformer, being convenient to transport, improving installation conditions to a large extent, and reducing the installation cost; long leads are not required in use, thereby saving installation material, obviously improving the signal acquisition accuracy of the voltage transformer, and substantially improving the anti-interference capability; and antirust treatment is carried out on the surfaces of the supports in the integrated structure, so that the supports are not easy to age, and the voltage transformer has the advantage of long service life.
