Mode and insulating materials performance etc..Just there is a kind of impregnating varnish in the insulating materials of transformer, transformer performance is influenced
Very beat.Impregnating varnish fills the gap in insulation system and micropore, impregnated for impregnation motor, electric apparatus coil
Object surface forms continuous paint film, and coil is made to be bonded to a solid entirety.Impregnating varnish divides solvent impregnating varnish and solvent-free
Impregnating varnish two major classes, relatively for solvent impregnating varnish, solvent-free immersion paint mainly has following advantage：Filling rate is high, insulating layer
Air-gap-free, paint film are smooth solid；Solidification fugitive constituent is low, and environmental pollution is small, and process conditions are good；Convenient for automating impregnation technology.
Although the various types of solvent-free insulated impregnating varnish, but still can not meet the requirement of increasing transformer insulated performance.
Currently, the equipment such as transformer, electrical equipment and electrical all develop in the direction towards environmental protection and energy saving, and then require impregnating varnish also towards environmental protection
Energy saving direction develops, therefore proposes increasingly higher demands to the gel and hardening time of impregnating varnish.
