Discover how electrical insulation kraft paper serves general transformer insulation needs. Technical analysis of dielectric strength, thermal stability, and moisture resistance from Suzhou Hanyao New Materials Co., Ltd.

​PTFE Glass Cloth Adhesive Tape, also commonly known as PTFE fiberglass tape, is made of fiberglass fabric as the substrate, impregnated with PTFE coating and high-temperature pressure-sensitive adhesive. Balancing the mechanical tensile strength of fiberglass with the low friction, anti sticking, chemical corrosion resistance, high temperature resistance, and insulation properties of PTFE, it differs from pure PTFE film tape in that it has stronger tear resistance and is widely used in various industrial production line scenarios with high temperature, adhesive, resin adhesion, friction and wear.

​ Electrical Insulation Kraft Paper belongs to the category of special industrial paper for electrical purposes. It is made from high-purity sulfate wood pulp and processed through special copying and calendering techniques. It has the characteristics of high dielectric strength, good oil absorption and impregnation performance, strong mechanical tensile strength, good flexibility, and low impurity content. It can form an oil paper composite insulation system with insulating oil and is widely used in fields such as power transmission and transformation, motor and electrical appliances, new energy, capacitors, rail transit, etc. It is the core solid insulation material inside high and low voltage electrical equipment, directly affecting the operational safety and overall service life of electrical equipment.

The substrate of Nomex Adhesive Tape is DuPont Nomex meta aramid paper, coated with acrylic/silicone pressure-sensitive adhesive, with long-term temperature resistance of 180-220 ℃, H-grade insulation, UL94-V0 self extinguishing flame retardant, high breakdown voltage, tear resistance, chemical corrosion resistance, arc resistance, and will not melt or drip at high temperatures. Core functions: High temperature electrical insulation, flame retardant protection, coil binding and fixation, isolation protection.

​ Polyimide film mica tape is a high-performance insulation material composed of powder mica paper as the insulation main body and polyimide (PI) film as the reinforcement layer composite. It combines the excellent high temperature resistance and fire-resistant insulation properties of mica with the high mechanical strength, corona resistance, and temperature resistance advantages of PI film; Compared with glass fiber reinforced mica tape, its tensile, tear resistance, and high-frequency pulse resistance are significantly improved, and it is widely used in variable frequency high-voltage motors, traction equipment, special high-temperature cables, and new energy electrical insulation scenarios.

​Electrical Insulation Filament Adhesive Tape is made of glass fiber/polyester fiber as the substrate and coated with pressure-sensitive adhesive. Its core functions include electrical insulation, mechanical protection, fixed bundling, temperature and wear resistance. It is widely used in motors, transformers, wire harnesses, reactors, and electrical equipment windings.
