HV COMBINED TRANSFORMER

Outdoor split-type combined transformer

This product consists of a combination of multiple single phase transformer. Each single phase transformer also is a small all-in-one combined transformer.

Ⅰ. Structure:
The combined transformer is made of outdoor special epoxy resin vacuum casting. It is small and assembled by 3pcs (three) single phase CT/PT combined transformer.

Ⅱ. Feature:
2.1. It has the characteristics of high dynamic thermal stability, high precision, low magnetic density, overvoltage resistance, light weight, and convenient installation.
2.2. The secondary winding of the current transformer has taps to obtain different current ratios.

Ⅲ. Service conditions:
3.1 Installation site: Outdoor and indoor dual use.
