Replace the conventional substation

in case of emergency；

Ease the tension of power supply；

Work as a temporary substation

Function and features

With all functions as a conventional substation has:

Including control，protection，lighting protection and step-down etc;

Distribute power to several branch circuit users，

Convenient installation、quick commissioning

After finishing the cable connection, it can come to work.

With precautions against earthquakes, concerning shock pad、temporary support bar、soft connection of circuit components.

Structure

Divided into HV part、main transformer、LV switchgear room

HV switch adopts ZF10-145（L）as main switch, barely mounted on a semi-trailer;

In LV switchgear room:

LV side switchgear、control power、DC panel and control protection device

LV internal switchgear1

Transformer features

Compact structure、light weight、small space coverage

Adopts flat oil conservator or fully sealed oil tank;

HV bushing laid lower part of the oil tank in order to lower the general height;

ONAF radiator to compress the total volume;

Internal body positioning and lead wire clamping should be reinforced to meet frequent transportation need.
