The low resistance anti-corona tape is a cured material made of alkali free glass cloth impregnated with low resistance anti halo paint after baking treatment. It has the characteristics of uniform resistance value, good elasticity, no scattering of black carbon particles, no pollution of impregnation, etc. The heat resistance grade is F, and it also has the advantages of excellent operation performance and high tensile strength.
Features and uses
The low resistance anti-corona tape is suitable for the anti-corona treatment of special motor coils such as steam turbine generators, hydro-generators and high-voltage motors. The specific use position is the linear anti-corona treatment of the coil. To balance the surface potential of the coil, reduce the potential of the coil surface and the iron core to prevent the air in the coil slot from being ionized and improve the service life of the motor.

Testing method
The surface resistivity of the low resistance anti-corona tape was measured with a multimeter. On the insulated wire rod, take a section of low resistance anti-corona tape, with a length of about (10cm ~ 15cm), and use prepared copper electrodes. The distance between the copper electrodes is the width of the low resistance anti-corona tape. During measurement, the electrodes should be Good contact with the strap surface, directly read the measured value of the multimeter. The average value of 5 samples was taken as the result.
Storage
The low resistance anti-corona tape is sealed with polyethylene plastic bags, and its outer packaging is in kraft corrugated boxes. The product is stored in a dry and clean environment in its original packaging. The storage period is 12 months at room temperature.
