Weftless tape, also known as weftless binding tape, is a strip of insulation binding material with a certain width, which is made by impregnating high-temperature heat-resistant unsaturated polyester resin with continuous twisted, unidirectional arrangement of treated alkali free glass fiber yarn.
The weft free tape produced by Xuchang Erek Insulation Products Co., Ltd. has good softness and viscosity, with a mesh like structure when opened, easy unwinding, no loose threads, and no stacking marks. This product has excellent properties such as high strength, impact resistance, high modulus, low elongation, no hysteresis, and no eddy current loss. Therefore, it is widely used for tightening the tension straps of transformer cores and coils. It is the winding and binding material for motors, traction motors, generators, lightning arresters, transformers, DC motors, welding machines, and high-voltage containers.
