35KV HIGH VOLTAGE OUTDOOR COMBINED TRANSFORMER

Split Type combined transformer

Ⅰ.Structure introduction:
This product consists of a combination of multiple single-phase transformers.
The combined transformer is made of outdoor special epoxy resin vacuum casting. It is small and has the characteristics of high dynamic thermal stability, high precision, low magnetic density, overvoltage resistance, light weight, and convenient installation. The secondary winding of the current transformer has taps to obtain different current ratios.
There is a wiring protection box at the secondary outlet end, and there is a outlet hole under it, which is convenient, safe and reliable for wiring and can realize anti-theft measures. There are four mounting holes on the base channel steel for installation.
