for Pouring type transformers and electric reactors
It is made by weaving alkali free glass fiber yarn and polyester fiber into gridding cloth with square holes, dehydrating at high temperature, soaking in epoxy resin adhesive, drying and curing. The product has a thorough epoxy resin impregnation, no bubble and local discharge inside, high insulation level, and can reach class H, mainly used for Pouring type transformers and electric reactors. It not only has high mechanical strength at room temperature, but also has high mechanical strength at high temperature to ensure safe and reliable operation.
Epoxy fiberglass mesh is widely used in dry-type transformer, reactor and other products with packing pouring. It is firmly combined with the epoxy resin of pouring coil. It can prevent the insulation gridding layer outside the coil from cracking due to the cold and hot effect of pouring parts and the huge electric power when the coil is suddenly short circuited, which improves the overall mechanical strength of the coil and has no effect on human health It is a kind of ideal environmental protection insulating mesh material, which has been widely used in western developed countries.
