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.
