Why use tunnel transformer

The reasons for using tunnel transformers when tunneling are mainly due to safety and electrical performance considerations. Tunnel transformer is a specially designed isolation transformer, which is used in tunnel construction and maintenance and has the following purposes:

Isolation and Safety: Tunnel transformers provide a safer working environment by isolating power. It reduces the risk of electric shock that may occur due to direct connection to the high-voltage power grid.

Voltage conversion: Transformers can convert the high voltage of the grid into low voltage suitable for use in tunnels. Such voltage is more suitable for lighting, ventilation and other power needs in tunnels.

Electrical Equipment Protection: Electrical equipment and tools used within tunnels often require specific voltages and currents. Tunnel transformers provide stable voltage and protect equipment from voltage fluctuations.

Reduce electromagnetic interference: In small tunnel spaces, electromagnetic interference (EMI) can cause problems with communications equipment and other sensitive equipment. An isolation transformer can help reduce this interference.

Adaptability: The tunnel construction environment is often harsh, so the tunnel transformer is designed to be more durable and able to adapt to humid and dusty environments.

Emergency response: When an accident or failure occurs inside a tunnel, tunnel transformers can ensure that key systems such as lighting and ventilation operate at safe voltages to facilitate emergency evacuation and rescue operations.

Therefore, tunnel transformers are important components in tunnel construction and operation. They ensure the safety, stability and reliability of the electrical system and provide a safe working environment for workers.
