summary:
The product is colorless or yellow transparent liquid. Like methyl silicone oil, it has better high temperature resistance, radiation resistance, lubrication and solubility than methyl silicone oil due to the introduction of phenyl into the molecular chain.
[performance characteristics]
It has excellent electrical insulation performance and excellent ozone resistance;
It also has the advantages of low viscosity temperature coefficient, low surface tension, shear resistance and large compression; in addition, it shows certain absorption to ultraviolet light.
[executive standard]
The product meets the following specifications: Hg / T 2366-1992.
[typical data]
[Purpose
250-30 is mainly used as impregnating oil for power capacitors. Compared with the same type of capacitors impregnated with capacitor oil, 250-30 can increase the capacity of a single set by 4-5 times, greatly improve the specific characteristics, wide operating temperature range, good safety and reliability, good gas evolution and excellent dielectric properties, It is an excellent impregnant and can also be used as transformer filling oil and pressure signal transmission medium of various pressure transmitters.
The working temperature is from - 50 ℃ to + 250 ℃.
[precautions]
The silicone oil can not be mixed with other products according to the user's requirements.
