Tanaka Electric
In the tunnel boring machine (TBM), this device serves the functions of voltage stepping and isolation. It acts as the power hub, regulating electricity, ensuring stable power supply, and supporting underground operations.
The design of this device ensures efficient use of electricity. When stepping up voltage, it consumes less energy, making it suitable for long-duration operations. This helps reduce costs and enhances the overall value of the equipment.
The device is equipped with a protective casing to prevent moisture and resist vibrations. It also features circuit breakers and current display instruments, ensuring that the transformer remains stable in tunnel environments.
