Standard Specification for Silicone Fluid Used for Electrical Insulation — 2 стр.
Реферат

This specification covers silicone fluid, polydimethylsiloxane, for use in transformers, capacitors, and electronic assemblies as an insulating or cooling medium, or both. Physical, electrical, and chemical tests shall be conducted on the specimen to check for quality conformance. The silicone fluid shall conform to the color, flash point, fire point, pour point, refractive index, viscosity, specific gravity, weight of volatile matter, dielectric breakdown, disk electrodes, VDE electrodes, dissipation factor, volume resistivity, neutralization number, water content, and PCB content requirements.

Область применения

1.1 This specification covers silicone fluid for use in transformers, capacitors, and electronic assemblies as an insulating or cooling medium, or both.

1.2 Silicone fluid covered by this specification is polydimethylsiloxane having a nominal viscosity of 50 cSt at 25C and a fire point of 340C or greater. This specification applies only to new silicone fluid. Information on in-service maintenance testing is available in appropriate guides.
