Biotransol HF is a dielectric fluid intended to use as an insulation and cooling medium in electrical distribution and power transformers. It is a natural ester-based dielectric fluid based on renewable vegetable oils. The fluid is readily biodegradable as per US EPA OECD 301B, environmentally friendly and non–toxic to aquatic life [1].
Introduction
Biotransol has been used by various transformer companies in their oil filled power transformers all over Asia and North America. Indian manufacturer Savita oils, with over 40 years of experience in manufacturing dielectric fluids, has managed to craft Biotransol to take technology in the direction of environmental sustainability. According to Savita, “Biotransol is your ideal dielectric fluid in applications requiring higher levels of efficiency, safety and environmental consciousness” [1].
Biotransol benefits
Biotransol has several benefits over mineral oils. Efficiency, safety and eco-friendliness are some of them [1]. It has higher fire point, breakdown voltage and excellent biodegradable characteristics besides enhancing fire safety and environmental sustainability. The transformers manufactured using Biotransol as an insulating fluid can be used in high risk and highly populated areas.
Various uses of Biotransol [1]
“When you have less space, and more population in that area [like in Mumbai, India], it means you need to have a solution that is very safe.”
Oil-filled transformer
Are we using Biotransol for manufacturing our transformers?
Atlas Transformer, a Toronto headquartered transformer company, has managed to use Biotransol in most of its oil-based transformers. This year we have delivered several natural ester filled transformers, meeting deadlines with high quality customer service. We have used FR3 fluid in all of our oil based transformers, allocating the benefits by reducing fire hazard and increasing life expectancy of its transformers [3].
10 MVA oil-filled transformer of voltage class 27.6/13.8 kV with five-legged core design
One of the major Biotransol based projects that was delivered by Atlas Transformer this year for a Calgary based company includes a high voltage 5,000/6,250 kVA FR3 oil immersed three-phase substation transformer. One of its kind, with two pole 33 steps OLTC along with AVR, was engineered to high quality, manufactured, tested and delivered within 14 weeks after the approval was received [3].
Our engineers have been working on the idea of creating technology that is eco-friendly without lowering the energy efficiency. Another great example of natural ester filled transformer that was manufactured and delivered by Atlas Transformer to an Ontario based customer is a 10 MVA transformer of voltage class 27.6/13.8 kV with five-legged core design. This oil filled transformer was airlifted by Cathay Pacific and considered as one of the heaviest shipments in their airlifting career. The transformer was manufactured, along with a spare unit, within four weeks. The first unit was airlifted to meet the urgency and the spare unit was shipped by sea and arrived in November [3].
Why are we not using mineral oil?
Although mineral oil is a low cost, readily available and great dielectric oil, many studies have shown that it has caused more harm to the environment in the past few years. The environmental damage is usually related to oil leaks during transportation, transformer explosions and fires.
What is the vision of Atlas Transformer?
Atlas Transformer has changed their business model to accommodate eco-sustainability over profit. During its 30 years in transformer business, Atlas Transformer has recognized a large demand shift from Mineral oil-based transformers towards eco-friendly transformers. We at Atlas are engaged to provide products that are skillfully engineered for a high level of efficiency, resulting in low energy losses and exceptional build quality. Keeping that vision in mind, Atlas will continue to provide eco-friendly transformers as per market demands [4].
