National grid is very important in the balanced industrial and infrastructure development of the country, It has to link the large power generation unites with the main populated cities industrial bases of the country. In addition it has to provide linkages with its neighboring countries for power interconnection for both supply and receiving.

Oswal sets up HV and EHV Transmission lines single / double circuit up to 800 KV AC on total turnkey basis. 

Electricity is usually transmitted long distances over desert, mountains and rivers through overhead power transmission lines where as underground power transmission is used only in densely populated areas.

Lattice / Tubular Towers can be offered in following designs- 

Choice of conductor depends on voltage and amount of power to transmitted keeping the losses to the minimum. 

Various types of insulators in glass and porcelain material that are used in transmission lines are  

Oswal provides transmission line hardware as per IEC, DIN, ASTM, BS AND BIS, and Standards viz.

Power generated at low voltages need to be step up for transmission over long distances and also need to be distributed and step down to required levels of consumption at industrial and domestic use levels – all this is achieved by electric sub stations. 

Oswal undertakes design, supply installation of – 

We also undertake sub stations automation system and SCADA wherein the status of sub stations equipment and measurements can be monitored locally of from remote load dispatch center; Sub stations automation system also includes fault diagnostics, trend management and maintenance. Power plant switchyard SCADA is provided as plant controls to avail operation from power plant control room,

We also undertake renovation and modernization projects of sub stations, our team is capable to carry out all activities civil works, electrical installation, testing and commissioning in scheduled time. 

Towns and villages close to urban centers can be connected to te national grid and electrified by cheaper modes of 11 KV or 33KV electricity transmission and distribution. 

MV transmission line refers generally to 11KV or 33KV and LV Lines refer to 0.4KV. We provide complete spectrum of services for distribution of power to rural areas and essentially consists of following equipment –

As an EPC company we cover all facets of activities:
