Soltex offers transformer oils for different conditions- Inhibisol 10, HyVolt C50A

Power on Year-Round with C50A

Friday, June 24th, 2022

Have you ever wondered how homes and businesses stay protected year-round in cold climates?  Believe it or not, the chemical Ergon HyVolt C50A – Canada CSA C50A Type II/IV takes on an important role in the power supply that keeps our power on and functioning throughout all seasons. And though the full name of this particular important substance is a mouthful, it is commonly referred to as C50A.


So how exactly does this chemical solution play into our homes and businesses being comfortably habitable year-round? C50A is what keeps power transformers cool. It acts as an insulator for connections and windings inside the transformers. Without it, our power supply would be incredibly unpredictable and dangerous. Insulating fluids such as C50A are used in quite literally all working oil-filled transformers, switchgears, and circuit breakers.


It’s important to also note that the Soltex C50A solution was developed specifically by Ergon and Soltex for Canadian climates. It has a lower viscosity and thus flows well even when temperatures drastically dip in the winters.


When it comes to the production of Ergon’s HyVolt C50A transformer liquid, there are several key components and processes involved. Produced from a severely hydrotreated naphthenic oil in our plant in Canada, it is engineered to meet the specification requirements defined for Type IV, Class A Arctic Grade use. This particular grade has a low pour point and low viscosity at very low temperatures and excellent oxidation stability which is integral to its essential function as discussed above. Ergon’s line of HyVolt Transformer Oils are fully miscible with insulating oils meeting the requirements set by ASTM 3487, IEC 60296, and CSA C50 as well:

  • PCB Free
    • Tested as per IEC 61619:1997
  • DBDS Free
    • Detection method using GC-AED
  • Passivator Free
    • Tested as per IEC 60666:2010
  • Metal Deactivator Free
    • Detection method using HPLC/GC-MS

Whether you live in a cold climate or maybe just visit occasionally, know that Ergon HyVolt C50A – Canada CSA C50A Type II/IV is working behind the scenes to keep you warm and safe in any indoor environment you encounter. It’s chemical solutions like these produced by Soltex that keep our world running, regardless of the weather.
