Key Features & Superiority

• Tailored for TBM Applications: Engineered with a deep understanding of tunneling operations, this substation features a compact internal layout and a minimized footprint. Its design is optimized to align with the elongated and space-restricted layout typical of TBMs, facilitating easier integration and installation within the limited space of a tunnel project.

• Robust Protection for Harsh Environments: Built to withstand the harsh conditions underground—including dust, moisture, and potential water sprays—the enclosure boasts a high IP55 protection rating. This ensures long-term operational integrity and safety against environmental factors.

• High Adaptability & Customization: Recognizing the diversity in TBM specifications and project requirements, this substation is highly adaptable. It supports a comprehensive suite of electrical protection, monitoring, and control functions. Furthermore, it can be customized in terms of configuration, protection schemes, and interface options to match the specific characteristics and power demands of different TBM models.

• Enhanced Reliability & Safety: The unit incorporates advanced protection features for the transformer and switchgear, which may include but are not limited to, overcurrent, short-circuit, temperature monitoring, and earth fault protection. This comprehensive protection safeguards both the electrical system and the TBM, minimizing downtime and enhancing overall site safety.

• Plug-and-Play Solution: As a fully prefabricated and tested unit, it significantly reduces on-site assembly time and commissioning efforts. This leads to faster project deployment, lower installation costs, and assured performance reliability.
