Insulating varnish was known as insulating coatings which is a coating with excellent electrical insulation. It has good electrical, mechanical and chemical properties. mostly varnish and colored paint. Insulating varnish is a special lacquer in lacquers. Insulating varnish is an important insulating material based on high molecular polymer and capable of curing into an insulating film or insulating whole under certain conditions. . Insulating varnish is composed of base material, flame retardant, curing agent, pigment and filler, and solvent.
An electrically insulating lacquer material is a dielectric whose basic feature is the transfer of electricity and its effects in a sense rather than a conductive manner. The IEC defines a dielectric as a polarizable substance and an electrically insulating material is defined as a material having a small electrical conductivity for isolating conductive portions of different potentials which including insulating varnishes, impregnated fibers, laminates, mica products, and pressed plastics. Five categories.
With the development of science and technology, people gradually realize that insulating materials are indispensable materials for electrical equipment. Technical indicators and operating life play a key role in the flame retardant coating based on olefinic resin. It should be added to the right amount and be compared to the "heart of the motor".
