What it does
Steps voltage up or down, so power can travel across the network and arrive at homes and factories at a level they can use.
Diwan Company for Electrical Industries
Electrical Transformers
We manufacture electrical transformers designed to serve distribution networks, power, and industrial projects — with a focus on iron-core quality, winding precision, insulation integrity, and performance testing before delivery.
