Underground Distribution

line LTL

As urban environments continue to grow and modernize, the demand for safe, reliable, and aesthetic power distribution networks has never been greater. LTL Transformer’s advanced Compact Medium-Voltage (MV) Substations are engineered to support the next generation of underground power infrastructure in major cities, commercial districts, industrial complexes, and high-density residential developments.

We design and manufacture fully integrated outdoor MV/LV enclosure solutions tailored for underground power distribution networks. These compact substations offer exceptional performance in environments where space constraints, safety standards, and visual appeal are top priorities.


Engineered for Urban Efficiency and Public Safety

LTL Compact MV Substations are built to deliver maximum reliability while minimizing environmental and operational impact. They are:

  • Fully enclosed for enhanced public safety

  • Optimized to withstand harsh outdoor conditions

  • Designed to reduce visual clutter in cityscapes

  • Built for fast installation and ease of maintenance

Every substation solution supports continuity of supply, making them ideal for mission-critical facilities such as hospitals, transit networks, shopping malls, and commercial towers.


Flexible Capacities & Custom Configurations

We offer a full range of standard and customizable options, with capacities between:

📌 100 kVA to 2,000 kVA

Whether it’s upgrading an existing underground grid or constructing a new development, our engineering team works closely with utilities, consultants, and developers to specify the best-fit solution for each application.

Available configurations include:

  • Ring Main Unit (RMU)-based systems

  • Transformer + LV panel integrated units

  • Metering & protection systems

  • Cooling and ventilation options for high-load environments


Quality You Can Trust — Proven in the Field

Every compact substation undergoes rigorous factory acceptance testing (FAT) as well as on-site performance validation to ensure long-term operational reliability. Our quality assurance system complies with:

  • International IEC standards

  • Utility and regulatory requirements

  • Robust safety and environmental guidelines

With decades of proven success in Sri Lanka and global markets, LTL continues to set the benchmark for world-class power distribution technology.


Powering Urban Progress — Today and Tomorrow

From smart cities to modern industrial zones, LTL Compact MV Substations enable secure, efficient, and future-ready underground power networks. Our commitment is simple: empower urban growth through innovation, safety, and sustainable engineering excellence.
