- The PT22-1ZHIxx voltage transformer is molded in a vacuum by Huntsman’s epoxy resin system with very good mechanical and electrical properties, withstands sudden temperature changes, and withstands the impact of long-term breakdown voltages. term.
- The PT22-1ZHIxx voltage transformer is designed with one or two ratios, the ratio can be changed by changing the connection on the secondary side.
- There are 1 to 2 secondary windings. The secondary winding is used for measurement or protection purposes.
- The voltage transformer can be installed in any position by the four bolts that go into the four holes on the base. The base is made of steel, solid structure and galvanized, resistant to wet environments…
