Product Description

China Factory direct sell toroidal power oil immersed transformer electrical oil transformer with aluminum

 

 Products introduction:

This series mining transformers are suitable for underground coal substations, underground pit yards, total air intake ducts and main air intake ducts. Although there are gas but no explosion hazard, they are also suitable for tunnels with relatively humid environment.

Features.

1. The fuel tank is structurally strong and can withstand an atmospheric pressure test. There is no oil storage cabinet on the cover. High and low voltage cable junction boxes are welded on both sides of the wall for cable connection. The high voltage coil has a rated voltage and a tap voltage of ±5%. The tap changer is used to change the voltage. When the voltage is changed, the power must be cut off first, and then the weather cover of the tap changer on the wall of the box is removed for conversion and tapping.

2. The low-voltage side of the transformer allows the "Y" connection to be 690V power supply, or it can be changed to "△" connection to 400V power supply. In the cable junction box, the secondary end is directly led out by six porcelain sleeves for user modification.

3. The lifting of the whole transformer is carried out by the hanging of the tank wall. The bottom of the transformer box is equipped with a trolley bracket. The bracket is equipped with mounting holes, which can be used to install the mine roller.
