MINE POWER spaces, long shaft transport routes, high humidity, dust exposure and mechanical stress define daily conditions underground.
In many operations, transformers, protection systems and monitoring units are still installed as separate components and interconnected on site. This fragmented structure increases installation effort and creates additional interfaces, leading to more cabling, testing and coordination work, according to Becker Mining Systems. Every individual unit occupies valuable space – a critical factor in already restricted underground roadways.
Maintenance presents a particular challenge. Large, monolithic systems are difficult to service in narrow drifts. If a central unit requires major repair or overhaul, it often has to be removed and transported back through the shaft. This process is time consuming, resource-intensive and can result in extended production downtime.
At the same time, electrical safety requirements are increasing. Higher power densities – particularly in the 600 V range – demand reliable protection mechanisms, including rapid arc detection. Systems must operate robustly under harsh environmental conditions while ensuring the protection of personnel and infrastructure.
Standardisation is another growing priority, with mining operators requiring
scalable and repeatable solutions that simplify training and streamline spare parts strategies.
“ Increasingly, this standardisation is expected to go hand in hand with modularity,” Becker says.“ A welldefined core design that can be configured quickly for different voltage levels, mine layouts or operational requirements allows operators to adapt to site-specific conditions without redesigning the entire system architecture.”
Such a modular baseline supports faster deployment, easier replication across multiple sites and long-term planning consistency, Becker says – advantages that individually assembled systems struggle to provide.
“ Underground power distribution is therefore no longer just about supplying energy,” the company explains.“ It has become a key contributor to operational stability, maintenance efficiency and overall safety performance.”
With the DTS – Disconnecting Transformation Sled – Becker Mining Systems says it has developed an integrated solution specifically designed to address these challenges. The concept focuses on combining essential functions within a compact, standardised unit while prioritising

serviceability and transport efficiency. The DTS integrates a DURATRANS™ transformer, the ARCGUARD ® arc protection system and ENDIS Compact Station 4000 technology within a single enclosure. By delivering a pre-assembled and factorytested system, the number of interfaces is reduced and installation time is shortened, the company claims.
