Product Description
Safety is a top priority in any electrical system, and dry type transformers are no exception. Our flame-retardant cast resin is designed specifically for dry type transformers to offer an extra layer of safety. The resin is formulated with flame-retardant additives that give it the ability to resist combustion.
In case of an electrical fault or overheating, the flame-retardant cast resin can prevent the spread of fire, minimizing potential damage and risks. This is especially crucial in areas where fire safety regulations are strict, such as hospitals, schools, and high-rise buildings. Dry type transformers with our flame-retardant cast resin not only meet but exceed safety standards.
The resin also has excellent electrical insulating properties, ensuring smooth power transfer. Moreover, it is resistant to moisture and corrosion, maintaining its flame-retardant and insulating capabilities over time. By using our flame-retardant cast resin in dry type transformers, you can have peace of mind knowing that your electrical systems are safe and reliable.
