outdoor HV dry box type combined transformer

General:

This type of combined transformer (also known as measuring box) is composed of voltage and current transformers. Products for AC 50Hz, rated voltage 10kV below the three-phase line, power supply voltage, current and electric energy measurement and relay protection, suitable for urban network, rural network outdoor substation, can also be used in industrial enterprises all kinds of transformer distribution office. Combined transformers equipped with active and reactive power meters are called high-voltage power metering boxes. This product can replace oil-immersed combined transformer (metering box).

Key Feature

• The voltage transformer is made of indoor epoxy resin cast structure with exposed core and stacked with high-quality cold-rolled oriented silicon steel sheets. Primary and secondary coils are installed on the center column.

• The current transformer is also made of indoor epoxy resin cast structure, the iron core is closed, and it is made of high-quality cold-rolled oriented silicon steel sheet.

• Two voltage transformers (PT) and two current transformers (CT) are assembled in a closed iron box to form a whole.
