Insulating Oil For Transformers I-20
Heat dissipation: During the operation of the transformer, the magnetic core will generate a large amount of heat. Transformer oil has good thermal conductivity and can transfer this heat from the magnetic core to cooling devices (such as coolers or fans), ensuring the normal operation of the transformer.
Product Details：Insulating Oil For Transformers I-20
I-20 transformer oil is suitable for distribution transformers, power transformers, reactors, and similar oil-filled electrical equipment of all voltage levels with a Lowest Cold Startup Temperature (LCSET) above -20°C.

1. Classification: Transformer oil
2. Executive Standard: GB 2536-2011 I-20 ℃ (general).
3. Application Scope: I-20 transformer oil is suitable for distribution transformers, power transformers, reactors, and similar oil-filled electrical equipment of all voltage levels with a Lowest Cold Startup Temperature (LCSET) above -20°C.
4. Performance requirements for transformer insulation oil：
(1) Dielectric loss: Dielectric loss refers to the electrical energy loss of insulating oil under the action of an electric field. The lower the dielectric loss, the better the insulation performance of the insulating oil.
(2) Antioxidant performance: Antioxidant performance refers to the ability of insulating oil to maintain stability under the action of high temperature and oxygen. The better the antioxidant performance, the longer the lifespan of the insulating oil.
