200kVA 440V/1000V Step Down Electrical Isolation Copper Dry Type 0-2000kVA/Custom Low Voltage 0V-3.3kv Copper Distribution Power Transformer Manufacturer

Product Description

 

Product Description

Description:

This three-phase transformer in shield machines is for voltage boosting and isolation. It precisely meets the power needs, lifts voltage, and blocks interference. It offers stable, pure power for smooth tunneling.

1.Efficient Boost, Stable Output

Using advanced tech and copper winding, it boosts voltage well. It powers key parts like cutter heads. Stable voltage avoids failures, extends equipment life, and cuts costs.

 

2.VPI Treated, Good Protection

VPI treatment boosts insulation. In tunnels, it resists moisture, dust, and EMI. It runs reliably, has fewer faults, and supplies power steadily.

Operation Environment

A)  Altitude: Not exceeding 1000m, shall be derating used if above 1000m;
B)  Ambient Temperature: -25ºC~55ºC.
C)  Relative Humidity: ≤95%;
D) As to the installation site, to make sure no bad effect on transformer insulation, chemical deposition, dust, and other explosive or erosive medium.
E) The supply voltage approximates sinusoidal wave, and the three-phase voltage is relatively balanced.
