14 Important Reasons to Choose TEMCo as the Transformer Manufacturer supplier for Your Stock and Custom Transformers:

Maximum efficiency, lowest losses, trouble-free performance, longer life

TEMCo Transformer Manufacturer Plus+ Features
Copper Power Transformer Windings Can Make the Difference.
Our copper coils are wound with 100% pure electrolytic high conductivity copper for long, trouble-free transformer life.  If your budget is tight, we also offer other choices.

Our Power Transformers are Manufactured to Provide More Power at Less Cost.
TEMCo power transformers reduce electricity bills, meaning a faster payback. Data based on popular 45 kVA size shows $1000/year savings. That is $10,000 saved over 10 years!

Costs based on .07¢ per KW / h. Comparison is between TEMCo WATT+PLUS copper-wound transformer and conventional unit made of copper (if available).

Our unique wound core construction vs. conventional core.
The unique oval shape of TEMCo wound core construction ensures that flow of magnetic flux is carried in direction of cold-rolled grain-oriented steel for minimal core loss.

A conventional transformer uses stacked lamination core assembly. 90° square corners contribute to high core losses.

Easily accessible power transformer terminal board.
Voltages are clearly shown to facilitate trouble-free connecting of line and load cables. All coil leads are directly brazed to terminal board studs to prevent heating, loosening.

Designed for cooler running.
Most all TEMCo distribution transformers are manufactured with heatproof Class 220°C materials only and designed to operate well below the maximum allowable temperature rise of 150°C.

More effective heat transfer.
To provide effective heat transfer, all our core and coil assemblies are double dipped in solventless, non-hygroscopic resin and baked thoroughly.

Quieter operation.
Anti-vibration isolators between the element and enclosure reduce vibration transfer to the surrounding structure, ensuring quieter operation.

Power Transformer Manufacturer almost 40 years
TEMCo's extensive experience allows us to specify specifications to manufacture transformers to the highest quality meeting customers various needs.

TEMCo WATT+PLUS™ technology means superior performance, maximum efficiency and lowest losses with all types of load - under all conditions.

We use the T-T connection for our three phase distribution transformers to derive the inherent benefits of single phase construction: high short-circuit strength, rugged physical integrity and superior reliability. These characteristics are normally available only on pole-mounted utility-grade, oil-filled transformers where every watt lost and every hour of downtime is critical.

Through the use of 100% copper windings, liberal designs and wound cores, most all TEMCo general purpose transformers have full load efficiencies above 97.5%. Low magnetizing currents averaging 1% of rated amperage mean that more power is available to handle useful customer load. Because of their efficient design, our transformers comply with the CSA-802-94 standard for maximum losses.

Characteristics of TEMCo transformers with the T-T connection include
· 30° phase displacement between primary and secondary
· 120° phase angular relationship between the line voltages and between the line currents.

Interlacing of windings on both coils for better coupling results in superior regulation with a maximum of 2.5% voltage drop at 1.0 power factor. This means higher peak loads are possible before minimum low voltage limitations are reached, allowing required voltages to be applied to critical equipment at greater distances.

Even under the most severely unbalanced load conditions, a TEMCo transformer with its 'stiff' internal neutral will not shift, ensuring that phase voltages are the same to within .2%.

Thanks to our unique design configuration, even TEMCo transformer manufacturer standard distribution transformers offer significant advantages over other standard designs. This will be especially evident where there are changes and additions to existing installations affecting the percentage of non-linear component.

In the T-T connected power transformers by TEMCo, the tripleN harmonics are cancelled in the magnetic circuit and do not flow in the primary windings as in competitive designs. This results in a 14% reduction in copper losses, less heat and extended transformer life.
