Mobile Substation Transformer

Mobile substation transformer is a mobile complete set of equipment composed of dry-type transformer, high-voltage load switch or high-voltage vacuum switch, cable connector and low-voltage feed switch or low-voltage protection box etc.It can be used to provide power supply for comprehensive mechanized coal mining equipment or hand-held electric drill and lighting in places where the underground environment is damp and contains gas and coal dust with the risk of explosion.

Winding:
The winding must be especially protected - both against high electrical stress due to external over voltages and against mechanical overloads by short circuits. They are made of copper or aluminum. Low-voltage windings are made of strip or flat wire while high voltage windings are manufactured from round or profile wire. ("diamond-dotted paper") bonds the winding into a compact block while drying and increases the short-circuit capacity additionally.

Magnetic Core lamination:
The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steel lamination insulated on both sides,guaranteeing low losses and low noise. These values are even improved by laser treatment. It is protected on the surface with aflash-proof varnish in order to prevent the sheet from corrosion and to reduce the noise.

Oil tank:
Whether during transport or operation -the tank must be absolutely tight under mechanical stress. We have vast constructional experience, the most modern calculation methods and high-quality welding work. Special attention is paid to corrosion protection. Pretreatment of the surface is processed by phosphating pickling, contributes to corrosion protection, just like multi-coating with preset drying times for each layer. On request, hot-dip galvanization provides for even better protection.
