With time and requirement of the customer, energy efficient transformers manufacturers have made many changes to the transformers standards. Many products have preceded these transformations for transformers in order to optimize the manufactured products for environmental concerns. Government of India and other countries are encouraging users to get energy efficient products like energy efficient transformers to lower the CO2 emissions.
Apart from contributing to the environment, energy efficient transformers realize substantial savings in operating costs. Thus, they put direct impact on the initial investment that is evaluated over a period of time.
How manufacturers of energy efficient transformers design their products?
Such transformers are designed and built by manufacturing units to meet or exceed the requirements for general applications. There are some construction features that you should know-
- Core constructionÂ
Transformer cores are produced from the finest quality, cold rolled, non-aging, silicon steel lamination. These are precision cut to close tolerances, which eliminates burrs and enhances performance. Manufacturers use complete miter stepped core construction for high efficiency transformers.
- Coil construction
Coils are made in either copper or aluminium material. Manufacturers wound the coils precisely with continuous copper or aluminium conductors and balance them electrically to lower the axial short-circuit forces. They use the duct stick that allows air to flow and this promotes superb cooling. Duct stick use also provides superior radial mechanical strength.
- Insulation system
The insulation rating is the maximum allowable winding temperature at which the transformer is operated at 40 degrees Celsius. Manufacturers classify the insulation systems on the basis of temperature rating. Manufacturers of energy efficient transformers use quality insulation materials that meet all the UL standards.
- Terminations
Manufacturers provide both high and low voltage terminal lug connectors to the transformers. These connectors are suitable for both aluminium and copper cables. These connectors make the installation easy without the requirement of purchasing connectors separately. So, you save the time and money altogether.
- VPI or vacuum pressure impregnation
The VPI is a process performed by manufacturing units to ensure that the insulating resin penetrates all voids with perfection and also provides finest output.
The results achieved from this process are better than simple dip and bake operations.
All these guidelines are issued by energy efficient transformers manufacturers. If there is any confusion or you want to ask something, go ahead. The experts are waiting for your feedback and queries.
