Isolation transformer TDF-20

electrical power supplydryfor railway applications

Product Overview: The transformer specifically used for powering the control units of shield tunneling machines stably converts electrical energy and ensures safety through isolation. It provides reliable power support for precise control and continuous operation of shield tunneling machines in complex tunnel environments. It is a crucial power guarantee for smooth tunneling. Specific Introduction: 1. High Reliability for Harsh Tunnel Environments In view of the harsh environment of tunnel construction by shield tunneling machines, such as high humidity, strong vibration and much dust, the transformer adopts special protection designs and a sturdy structure. It has functions of waterproof, dustproof and shockproof, ensuring stable operation under harsh conditions to meet the long-term continuous operation needs of shield tunneling machines. 2. Precise Voltage Stabilization for Control Assurance It provides precise and stable voltage output for the control units of shield tunneling machines. In the complex power system of shield tunneling machines, it effectively resists grid fluctuations, harmonic interference and other impacts, ensuring the normal operation of various sensors, controllers and other components in the control unit. This ensures the precise control of the tunneling posture and construction safety of shield tunneling machines. * Operation Environment A)Altitude: Not exceeding 1000m, shall be derating used if above 1000m; B)Ambient Temperature: -25D-55D; C)Relative Humidity: <95%; D)As to the installation site, to make sure no bad effect on transformer insulation such as chemical déposition, dust, and other explosive or erosive medium.
