Application characteristics of G11 Epoxy Board

G11 epoxy insulation board insulation materials is made of imported electrician non-alkali glass fiber cloth impregnated with imported epoxy resin, and added with corresponding imported flame retardants, adhesives and other additives; cardboard-like insulation material processed by hot pressing. Flame retardant grade UL94-VO grade, good mechanical properties at high temperature, good processing performance and insulation performance, is a common raw material for insulating structural parts in motors and electrical equipment, G11 epoxy insulation board can also be used in humid environments and transformers Used in oil, high voltage switchgear, high voltage switch, etc.

So how high temperature can G11 epoxy insulation board withstand? What is the breakdown voltage? In general, G11 epoxy board can work continuously in the working environment of 200 ℃, the breakdown voltage specification value is greater than or equal to 40KV, the typical value is 80KV.
Application characteristics of G11 epoxy insulation board: First: various forms. Various resins, curing agents, and modifier systems can almost meet the requirements of various applications on the form. Its range can be from extremely low viscosity to high melting point solids. Second: easy curing. Using various curing agents, the epoxy resin system can be cured in the temperature range of 0 ~ 180 ℃; third: strong adhesion. The existence of polar hydroxyl and ether bonds inherent in the epoxy resin molecular chain makes it highly adhesive to various substances. Epoxy resin has low shrinkage when cured, and the internal stress generated is small, which also helps to improve the adhesion strength; Fourth: low shrinkage. The reaction of the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are released. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage (less than 2%) during curing; Fifth: Mechanical properties. The cured epoxy resin system has excellent mechanical properties.
