Phenyl silicone oil performs well in electrical properties. The following is a detailed analysis of its electrical properties:

1. High dielectric constant
Phenyl silicone oil has a high dielectric constant, which gives it certain advantages in electrical insulation materials. A high dielectric constant means that the material can store electrical energy better and show a stronger polarization effect in an electric field. This is especially important for electrical equipment that requires high capacitance performance.

2. Low dielectric loss tangent value
The dielectric loss tangent value is an indicator of the energy loss of a material in an electric field. Phenyl silicone oil has a low dielectric loss tangent value, which means that in an electric field, it is able to convert more electrical energy into capacitive energy storage rather than into heat or other forms of energy loss. This helps reduce the energy loss of electrical equipment and improve the efficiency of the equipment.

3. Excellent electrical insulation performance
Phenyl silicone oil has excellent electrical insulation performance and can effectively isolate the conductors of electrical equipment to prevent current leakage or high voltage discharge. This performance makes phenyl silicone oil widely used in electrical insulation materials, such as insulating impregnation agents or potting materials for power capacitors, transformers, motors and other equipment.

4. Corona resistance
In high-voltage electric fields, electrical equipment may produce corona discharge, which can cause damage to the equipment. Phenyl silicone oil has good corona resistance, can remain stable in high-voltage electric fields, and is not prone to corona discharge, thereby protecting electrical equipment from damage.

5. Ozone resistance
Ozone is a strong oxidant that can corrode and damage electrical equipment. Phenyl silicone oil has excellent ozone resistance, can remain stable in ozone environments, and is not easily oxidized and decomposed, thereby extending the service life of electrical equipment.

In summary, phenyl silicone oil performs well in electrical properties, with advantages such as high dielectric constant, low dielectric loss tangent, excellent electrical insulation, corona resistance and ozone resistance. These properties make phenyl silicone oil have a wide range of application prospects in the manufacture and maintenance of electrical equipment.
