A dry type transformer consists of a magnetic core designed by cutting-edge technology that utilizes forced or natural air cooling instead of oil. Best fitted in well-ventilated spaces, these transformers operate through voltage changes, that require high-temperature insulations for cooling, releasing the dry type transformer manufacturers from building fire-resistant walls around them. Additionally, they are devoid of rotating parts which significantly reduces maintenance costs offering durability and reliability.
Unlike their liquid-type counterparts, they do not emit toxic gasses, which leaves a positive ecological impact and a scope for indoor installation. Dry type transformers play a significant role in promoting eco-friendly power solutions due to their inherent environmental advantages.
Non-flammable and Non-toxic
The dry type transformers are specifically designed using solid insulating materials like epoxy resin, and fiberglass that possess inherent flame-retardent properties. These solid insulations can withstand high temperatures without decomposing or releasing flammable gasses, further enhancing fire safety. This feature enhances safety and minimizes environmental hazards associated with oil spills and leaks. Due to their non-flammable nature, these transformers are used in solar and wind farms, critical infrastructure facilities such as hospitals and data centers, and harsh environments with potential fire hazards like chemical plants and mining operations.
Reduced carbon footprint
Dry type electrical transformers do not require regular oil maintenance, such as oil changes and disposal. This eliminates the carbon emissions associated with oil production, transportation, and disposal contributing to a lower carbon footprint. By adopting dry type transformers, organizations can actively participate in carbon reduction initiatives and address the global challenge of greenhouse gas emissions by driving electricity from renewable energy sources.
In 2022, Canada generated around 69% of electricity from renewable power resources. Furthermore, the country expects to achieve 90% of the electricity source to be from hydro, solar, and wind by the year 2030. This is expected to increase the demand and provide lucrative growth opportunities for dry type transformers in Canada.
Waste depletion
The dry type transformers cater to waste reduction in numerous ways. Devoid of oil, these transformers do not require oil disposal or replacement which depletes the generation of spawning of hazardous waste. Moreover, frequent replacement is not necessary for the dry type transformers as they have longer lifespans in contrast to the others. This durability and longevity noticeably reduce the accretion of electronic wastage making this type of transformer a conscious choice towards sustainability.
Improved energy efficiency
High-quality core materials and advanced winding techniques are in these transformers which minimizes the energy loss due to hysteresis and eddy currents. Furthermore, diminished stray losses through careful magnetic shielding and optimized winding configurations lower operational costs. Besides, natural and forced coolants offer higher energy efficiency compared to oil-filled transformers. The solid insulation materials provide better heat dissipation, reducing energy losses and contributing to an overall power saving.
Smaller size and weight
Dry type electrical transformers are significantly smaller and lighter than oil-filled transformers. This compact size allows for easier installation in space-constrained environments, such as indoor electrical rooms or compact substrains. The small size also reduces the transportation costs which is particularly beneficial for projects in remote areas with limited access.
The compact size and design provide greater flexibility during installation. They can be easily maneuvered into tight spaces and installed in various orientations to suit specific site requirements. Hence for places like solar and wind power plants where space optimization is crucial. By leveraging the compact size industries and organizations can optimize their power distribution systems, save space reduce costs, and enhance the overall efficiency and aesthetics of their electrical infrastructure.
End note
Increasing adoption of renewable energy has had a positive impact on the demand for dry type electrical transformers. Moreover, dry type electrical transformers manufacturers are currently focusing on the optimization of efficiency involving enhanced core designs and advanced winding techniques to cater to the sustainable goals of the industry.
Dry type transformers can operate in harsh environments, including areas with high humidity or corrosive atmospheres without compromising their eco-friendly benefits and competence. By adopting dry type transformers, industries, and organizations can contribute to cleaner and more sustainable power distribution systems while enhancing safety, reducing operational costs, and minimizing their environmental impact.
