Power Generation Equipment: Transformers and Substations

What the power generation equipment range includes

The category lists six items in three groups. Most of them sit on the step-down side of the grid, where power from a plant or a long line is brought down to a voltage a site can use.

• Outdoor Substations up to 400 kV (4 models): the 1000kVA 3-phase oil cooled distribution transformer, a 500kVA distribution transformer, a single phase 400kVA unit and the three phase 400 kV model.
• Gas Insulated Sub Stations (1 model): a sub station insulator built to keep its dielectric strength and hold firm in small, sealed switchgear.
• Industrial Electrification (1 service): wiring and fitting work for plants and factory estates that are adding new power.

Choosing a distribution transformer

Three things drive both the lead time and the quote for a transformer: its power in kVA, its voltage class and the way it is cooled.

Capacity and voltage

Start from the peak load of the site, then add room to grow. A small works or a rural feeder may suit a 400kVA or 500kVA unit, while a large plant often needs 1000kVA. The input side must match your grid, and the output side must match your loads.

Cooling and site conditions

Oil-cooled units are the usual choice for outdoor yards, since the oil carries heat away and helps guard the windings. Dry types are sometimes asked for indoors, where fire rules are strict. Tell us about heat, dust, altitude and coastal air at the site, as these can change the design.

Single phase or three phase

Single phase units often serve light rural loads and long feeders. Three phase units run motors, pumps and heavy plant, which is why most industrial buyers ask for them.

Substation parts and industrial electrification

A substation is more than its transformer. Insulators, switchgear and busbars keep each circuit safe and apart. Gas insulated designs pack this gear into sealed metal tanks, which saves space in towns and on tight plant sites. Outdoor yards that use open air as the insulator take more room but are simple to extend.

For buyers who need more than hardware, our industrial electrical contractors service covers the wiring and fitting work behind a plant's power backbone. The scope is agreed per project.

Tender supply for utilities and government projects

Grid and government power projects are nearly always put out to tender. The spec for power generation equipment usually fixes the transformer rating, the voltage class, the efficiency standard and the delivery date.

We can quote against your single-line diagram or tender spec, and plan the build around the date in the award. Factory test reports and data sheets can be sent before the goods ship, and we confirm the exact set when we quote. Our page on certifications and compliance documents explains what we can back with papers and what needs a local check.

Many utilities base their specs on the rules of the International Electrotechnical Commission (IEC). Projects backed by lenders often follow the energy access goals of the World Bank, so it helps to send any funder rules with your first message.

Related energy categories

Power generation equipment is often bought with lines, cables and solar or wind kit. See our power transmission equipment for overhead lines and towers, and pair a transformer order with solar or wind gear when a site uses more than one source.

Shipping and how to request a quote

Transformers are heavy and must stay upright, so they ship by sea on skids or in crates. The larger sizes often go on flat rack or open top units. Each shipment comes with a commercial invoice, packing list, bill of lading and certificate of origin.

To get a quote, send the kVA size, voltage class, cooling type, site details and the date you need it through our export team contact page by WhatsApp or email. We reply with a matched offer for your power generation equipment on the Incoterm you prefer, so you can plan the job or price your bid.
