Diamond Dotted Insulation Paper (Single & Double Sided)
Shenyang Deguang Electrical Technology Co., Ltd. specializes in providing a series of rhombic insulating paper products for transformers, including single-sided and double-sided point-shaped insulating papers. This product uses high-quality electrical insulating paper as the base material and is coated with B-grade epoxy resin adhesive on the surface. Therefore, during the winding and heat curing process of the transformer coil, it can provide excellent bonding performance.
This material possesses outstanding mechanical strength, excellent electrical insulation properties, good adhesion, stable winding performance, and also has good compatibility with transformer oil. Therefore, it is an ideal insulating material for oil-immersed transformers. Depending on different manufacturing requirements, this material also offers various coating types and specifications for selection.
