Flame-proof mobile substation

The Explosion-proof Mobile Substation consists of mainly explosion-proof high voltage switch, explosion-proof transformer, and explosion-proof low voltage switch. The transformer is bolted to the high and low voltage switches.

Excellent explosion-proof performance and mechanical strength

Vertically lifted structure adopted

Adopted cylinder-type HV winding to strengthen resistance to over-voltage

Excellent over-load resistance and insulated performance by using Dupont Nomex paper

Fire-proof, nonpoisonous air created

Low noise

Maintance-free

Our product advantages

Iron core

Superior silicon lamination for steel core, the lamination joint is processed by oblique cut angle and the latest new technology “seven-step”, which ensures small no-load loss and current.
Vertically lifted structure

Special anti-loose structure with vertical lifting ability, no internal looseness during transportation, easy to use and maintain
insulation material

Main insulating material is C-class and Nomex paper is adopted, plus the oxygen-free copper winding, which ensures small partial discharge, small no-load and load loss, and low temperature rise.
Enclosure

Excellent explosion-proof performance and sufficient mechanical strength.
High voltage switch

Equipped with rail wheels, strong impact resistance ability, detachable and adjustable rail gauge.
Low voltage switch

Multiple protective functions of overload, short circuit, leakage, leakage lockout, over-voltage, under-voltage and over temperature.
