TRANSFORMER OIL
Transformer Oil
Transformer Oil is a long-life insulation liquid used in high power transformers and switches.
Usage
Used in high power transformers and oil circuit breaker. IEC 60296 (03) meets the general specifications.
Properties
- High Antioxidant Effects: Antioxidants contain inhibitors against oxidation. This content ensures a long service life. No caking.
- High Performance Base oil dispersant Feature Naphthenic Base Oil: Naphthenic base oil structure with 100% foreign matter and particles are contained in the distributive property. Pollution does not allow the influence of isolation.
- High Electrical Insulation: The low of the resistance of the oil to electric stress and isolation provides a complete made.
- Superior Cooling Feature: It provides protection for cooling and heat generation.
- High Flash Point: In the section where the temperature is high to provide protection against glare.
- High Dielectric Factor: Increase the insulation performance and lifetime.
- Low Pour Point: Between the transformer and the conservator in all circumstances, it allows you to be comfortable even in the low temperature flow and ensure the reliability of the electrical connection.
