LS ELECTRIC Expands Underground Distribution Switchgear

Underground power distribution networks increasingly require compact switching systems that can improve fault isolation, reduce exposure to environmental conditions, and simplify deployment in dense infrastructure environments. In this context, LS ELECTRIC America introduced a new pad-mounted switchgear platform for medium-voltage underground distribution applications at IEEE PES T&D 2026 (4–7 May) in Chicago.

Switching and protection for underground power networks
The new pad-mounted switchgear is designed as a metal-enclosed outdoor unit integrating switches, fuses, and protection devices into a single enclosure. The system supports medium-voltage distribution applications up to the 35kV class and can be configured for either loop or radial distribution architectures commonly used across utility grids, industrial facilities, commercial sites, and renewable energy installations.

The ground-mounted enclosure is intended for installations where above-ground footprint and accessibility are important considerations. By combining switching and protection functions in a sealed outdoor enclosure, the system supports underground distribution strategies focused on network reliability and operational safety.

The switchgear is available in both dead-front and live-front configurations, allowing utilities and facility operators to align installation choices with maintenance procedures and operator safety requirements. Sealed compartments are designed to protect internal components from moisture, debris, and wildlife exposure, which remain common causes of service interruptions in outdoor electrical infrastructure.

Supporting fault isolation and grid resilience
Load-break switches and fused ways are integrated to support circuit isolation and fault protection during distribution network operation. These functions are particularly relevant in underground distribution systems where rapid fault localization and sectionalizing can reduce outage duration and simplify maintenance activities.

The switchgear was designed in alignment with ANSI and IEEE standards used across North American power distribution infrastructure, allowing integration into existing utility and facility electrical systems without requiring major architecture changes.

LS ELECTRIC positioned the product as part of its broader power distribution and smart grid portfolio, targeting applications tied to utility modernization, renewable energy interconnection, industrial automation, and grid resilience initiatives.
