Switchyard Engineering Services

Switchyard Engineering Services (FROM 11KV TO 400KV AIS & GIS)

For your power needs, there must be Substation to be exist at your premises. Substation doing multiple services, in which most essentials are : Transmission and Distribution, Substation normally transmitting power from the power generating plants to the Grid and Substation distributing power to the loads in the industry, as per the allotted maximum demand to the customer.

Transmission and Distribution (T&D) Network is needed to evacuate power from the Conventional and Non-Conventional power plants. The Substation of Power plants will come either AIS (Air Insulated Substation) or GIS (Gas Insulated Substation) subjected to the site conditions, available space to construct, Budget allocated for the project, Execution time involved and mainly trouble-free O&M (Operational & Maintenance) operation.

In India, Substation network voltage varies State wise, however common transmission voltages across India, are : 11KV, 22KV, 33KV, 66KV, 110KV, 132KV, 220 / 230 KV, 400KV, 765KV & 1200KV.  We (Chakra International Group) offering end to end solutions of Substation along with Transmission system from 11 KV to 400 KV. Requirement of Substation not only limited to power plants also there is necessity for the Power requirement of Townships, High rise buildings, IT Parks, SEZ Zone, Hospitals & Industries.

Here our services covers:

  • Feasibility Study:
    • Load flow Study, subjected to the power plant power handling capacity and connecting State / Central Govt running utility Substation.
