Mine Electric transformer
|Mine electric transformer is a set of movable power supply and transformation device, which is used to change AC voltage. It is suitable for mines with explosive atmospheres such as methane mixed gas and coal dust. The 6KV, 10KV power supply is converted into a low voltage power supply required for 400 (380), 693 (660), 1200 (1140), 3450 (3300) V coal mines.|
Mine Electric transformer
|It converts 6KV and 10KV power supply into low-voltage power supply needed in underground coal mine of 400(380), 693(660), 1200(1140) and 3450(3300)V. The shell of mine transformer is full corrugated, open-cover and open-top structure on both sides, which has the advantages of high mechanical strength, low temperature rise and good heat dissipation effect. The iron core is made of high quality low loss silicon steel sheet with low no-load loss, low no-load current and low noise. It adopts H-class insulation material and advanced insulation structure, which has good thermal stability and can be operated at full temperature at high temperature.|

|Delivery time||Normally, the delivery time is 20 days around|
The transformer main body usually in nude, and the accessories are packed in plywood case with steel structure, it’s worthy for ocean transportation.
Usually, the total weight under 45 tons, it’s available by kinds of container, above 45 tons, it’s available by bulk ship
Usually, we will dispatch experienced technicians to client’s installation site for the supervision service within 15 working days after getting official information.
1.What is the difference between mine transformer and ordinary transformer?
Mine transformer is small in size, without breathing apparatus and oil conservator, primary lead-out or secondary outlet in the side of the transformer is not at the upper end. The neutral line is not directly grounded.
2.Why mine transformers are widely used in explosion-risk areas
It not only prevents explosion and fire, but the enclosure can withstand overvoltage. Under normal circumstances, the casing can withstand the impact of 1.5 times the working pressure of the explosion in practical activities without being destroyed and without permanent deformation.
