CG Power Systems USA Inc (formerly Pauwels Transformers Inc) is a proven and reliable manufacturer of pad-mounted, primary unit substation, pole/platform-mounted and secondary unit substation three-phase transformers up to 2.5 MVA, with voltages up to 38 kV 250 kV BIL with de-energized tap changer (DTC), and Small Power transformers up to 10 MVA ONAN rating or 14 MVA ONAF rating with voltages up to 69 kV 350 kV BIL with and without load tap changer (LTC).

CG Power Systems USA Inc Medium Power: Three-phase transformers up to 60 MVA ONAF

CG Power Systems USA Inc has drawn on the extensive worldwide experience for the supply of three-phrase power transformers up to 750 MVA 765 kV to develop and provide its new range of highly reliable, cost-effective Medium Power transformers up to 37.5 MVA ONAN rating or 60 MVA ONAF rating with voltages up to 138 kV 650 kV BIL with and without load tap changer (LTC) and de-energized tap changer (DTC).

All products are built in accordance with the latest group technology available and designed with a common design platform ensuring the reliability, durability and low loss performance as those products manufactured at our worldwide established power transformer facilities.

All Medium Power transformers are completely designed, manufactured and tested at the company’s new facility located at Avantha Drive, Washington, MO. All designs are in accordance with the latest ANSI, NEMA and IEEE standards (or CSA and IEC standards upon request).

The Medium Power concept

CG Power Systems has a corporate vision of bringing reliable and innovative solutions to the marketplace. Our product development team has therefore taken technology of proven value from other transformer applications and applied these to Medium Power transformer designs in order to bring to you added value. Available design features such as flitch plate clamping structure, circular disc winding, step-lap stacked core, 3/8 inch steel tank walls, advanced cooling techniques, and the state-of-the-art manufacturing equipment, enabling to manufacture our Medium Power transformers cost-effectively.

Design flexibility for minimal total ownership cost

Our Medium Power transformer is customized to meet various specific requirements you may have, from low noise and reduced no-load loss, to lower load loss and overload ability. What is more, we help you to minimize your total ownership cost by using sophisticated design programs, developed in-house, to determine the best core and coils configuration in light of electrical, mechanical and economical factors. Valuable add-ons such as HV/LV air terminal cable boxes and/or throats including specific accessories, advanced controls and monitoring devices are available.

Based upon our worldwide proven track history, our experienced engineers will design the CG Power Systems Medium Power transformer to your expectations, making sure that the product you will receive is of utmost quality for the lowest cost possible such to guarantee performance for the next 40 years.

Reliability: maximum short-circuit strength

Our Medium Power transformer feature either circular layer, helical or disc winding design depending on the voltage class and rating of each individual winding, ensuring a maximum short circuit resistance. The round step-lap core is manufactured by a state-of the-art e-stacking core machine to minimize no load losses and hot spots. Copper conductor is always used together with upgraded insulation paper. Numerous similar designs have been previously put to the test by CG Power Systems and these have proven to provide a high level of reliability.

Design features

The CG Power Systems Medium Power transformer is available in a hermetically sealed tank oil preservation version, in a positive pressure oil preservation version or with a conservator oil preservation system. Heavy steel plates together with reinforced support members are used for tank construction to withstand full vacuum conditions. Lifting, rolling and jacking provision along with standard and non standard acces-sories and features can be provided in accordance with industry standards.

Testing and delivery

The CG Power Systems Medium Power transformer is subjected to rigid electrical tests in accordance with the latest revision of ANSI, General Requirements – C57.12.00 and Test Code – C57.12.90. Optional design tests, CSA and IEC tests are available upon request.Standardization of design and manufacturing allows CG Power Systems to guarantee quick deliveries. Our transformers are delivered with oil and assembled as much as transportation restrictions and road conditions allow us to. With the CG Power Systems’ Medium Power transformer, projects can be realized in a shortest possible time – thus underlining again: “CG Power Systems’ commitment to customer satisfaction”.
