About Transmission & Distribution

In a large and developing country like India, where there is huge demand for electric power, a matching network of transmission / distribution is the need of the hour.

Electrical Energy must be generated at the same rate at which it is consumed. A sophisticated Control System is required to ensure that the Power Generation very closely matches the demand. If the demand for power exceeds supply, the imbalance can cause generation plant(s) and transmission equipment to automatically disconnect and/or shut down to prevent damage. In the worst case, this may lead to a cascading series of shut downs and a major regional blackout.

For effective Transmission & Utilization of Electric Energy, a huge setup of EHV / HV / LV, Sub Stations & Transmission / Distribution Network is required.

At Shyam Steel we have started a new venture – Transmission & Distribution Division for executing EPC projects in this sector.
