TGSPDCL implements PMDT system to replace ground-level plinth method; 300 locations identified in Greater Hyderabad

Hyderabad: Telangana Southern Power Distribution Company Limited (TGSPDCL) has initiated the implementation of the advanced Pole-Mounted Distribution Transformer (PMDT) system to replace the conventional ground-level plinth method.

The initiative aims to enhance public safety, reduce space requirements, and improve operational efficiency, according to TGSPDCL Chairman and Managing Director Musharraf Faruqui.

Compact design, cleaner surroundings

Unlike the traditional plinth-mounted transformers that occupy 30–35 square feet and require nearly a week for construction and curing, the new PMDT system mounts transformers 6 to 9 feet above ground on 11-metre spun poles with a diameter of just 377 mm.

All essential components, including the HG fuse set, distribution box, and AB switch, are mounted on the same pole, resulting in a compact layout that eliminates clutter and prevents garbage accumulation around transformer locations.

Faster installation, easier maintenance

One of the key advantages of the pole-mounted system is speed. While conventional installations take several days, PMDTs can be installed within a single day.

Maintenance has also become safer and more efficient. Using a bucket ladder, a single staff member can conveniently carry out inspection and repair work. The design also allows easy integration of future underground (UG) cables, making the system future-ready.

Suitable for urban and congested areas

Currently, TGSPDCL is installing 63 kVA, 100 kVA, and 160 kVA transformers on 11-metre poles. While transportation of these poles is feasible on major roads, challenges have been reported in narrow lanes.

To address this, the utility is planning to deploy shorter 9.5-metre poles and is also examining the feasibility of installing higher-capacity transformers under the pole-mounted system.

Over 300 locations identified in Greater Hyderabad

Installation works are underway at 304 locations across Greater Hyderabad, with more than 100 transformers already commissioned successfully.

Under the “Currentolla Prajabata” programme, TGSPDCL is identifying transformers that pose safety risks or obstruct roads and replacing them with pole-mounted units. The rollout is expected to be expanded significantly in the coming months.

Step towards modern, safer power network

The TGSPDCL CMD stated that the PMDT system would play a crucial role in ensuring the safety, reliability, and aesthetics of the power distribution network, especially in densely populated urban areas.

The initiative marks a decisive shift towards smarter and more resilient power infrastructure in Telangana, aligned with the state’s urban development and public safety priorities, he added.
