PRODUCT DETAILS
Product description: 

Functioning for insulation, cooling and arc extinguishing, transformer oil is used in oil-filled electrical equipments, such as transformers, reactors, mutual inductors, casings, oil switches, etc. Transformer oil contains almost 3, 000 kinds of hydrocarbon compounds, with main components of alkane (around 40% - 60%), naphthene (around 30% - 60%), and aromatic hydrocarbon (around 8%), but no long-chain alkenes or alkynes. 

Features:

Safty:
The product flash point is above 140ºC, higher than the national standard and IEC standard.
Excellent electrical properties:
The product insulation strength is high, the breakdown voltage is above 55kV, far higher than the national standard and IEC standard; DDF at 90ºC is below 0.0009, far below the national standard and IEC standard.
Low viscosity and good cooling effect:
The viscosity of 40ºC is 6-10mm2/s, far lower than the national standard and IEC standard, with better thermal conductivity, the product is conducive to improving the cooling effect of the transformer.
Small density:
The density of 20ºC is 840-880kg/m3, lower than the national standard and IEC standard, it is conducive to curb the water of transformer to generate ice in winter, favorable for safety production.
Long life:
It has excellent oxidation stability and thermal stability, acid value and precipitation oxidation is very small after experiment. It can long-term ensure the transformer oil not easy to aging deterioration under the condition of high temperature work, prolong the service life of the equipment.
Health and environment: 
Raw materials are conform to food grade white oil standard, harmless; not only contain PCB, but also non-toxic to human body, soil and water.
Recoverable:
No poisonous gas or liquid is produced in the process, the product can be refined and used again.
Good compatibility:
It is lower corrosion and solubility and more compatible of grease paper, adhesive tapes, washer, glue and wire insulation materials.
 
Application: 

The products are good to be used as the insulation and heat conduction medium for the electric equipment, such as transformer, transformer and casing, and it's also suitable to be used as insulation and arc extinguishing medium for oil circuit breaker. 

Notice: 
1 Material of the containers used for storage and transportation (storage tanks, rail tankers, tankers, tanks, etc. ), and the pipelines has to meet
certain compatibility requirement for the transformer oil. 
2 To avoid oil emulsion, transformer oil's containers, including their pipes, must be strictly separated from other containers. Also, they must to be damp-proof or be sealed from exposure to moist air.
