Transformer oil
Transformer oil T-1500
Specifications:
Segments: Industrial Equipment | Power
Available in: 200 L
Used for filling power and measuring transformers, oil circuit breakers, reactor equipment, and other high-voltage apparatus as the main electrical insulating material, including performing the function of an arc-quenching medium.
Produced from sulfurous paraffinic crude oils using selective refining and hydrogenation processes. Used for insulating live transformer components, heat dissipation, and preventing moisture ingress.
- Good stability against oxidation;
- The ability of oil to maintain its parameters during long-term operation;
- High dielectric strength (breakdown voltage not less than 60 kV).
