Naphthenic Transformer Oil For Transformers T-30
Environmental protection: some new insulating oils, such as vegetable oil-based insulating oils, have better environmental performance, biodegradable, reducing the impact on the environment.
Stability: Insulating oil can maintain its stable performance in a wide range of temperatures, ensuring that the equipment can operate reliably in a variety of environments.

Impregnation: Insulating oils can fully impregnate solid insulating materials, fill the voids and air bubbles, improve insulation strength, and prevent the intrusion of air and moisture.
Protective properties: Insulating oil can also prevent the internal metal parts of the equipment from corrosion and oxidation, and improve the durability of the equipment.

1. Classification: Transformer oil
2. Executive Standard: GB 2536-2011 T-30 ℃ (general).
3. Inspection & Use：
(1) Regular inspection: The stored transformer oil needs to be inspected regularly to check the sealing, cleanliness and chemical properties of the oil. At the same time, according to the use of oil, regular replacement of transformer oil to ensure the quality and service life of the oil.
(2) Reasonable use and replenishment: the stored transformer oil should be used reasonably to avoid unnecessary losses caused by excessive consumption. When it is necessary to replenish the transformer oil, the transformer oil with the same specification and quality as the crude oil should be used to ensure the normal operation of the transformer.
