Common application
The technical personnel should select the mica tape with appropriate width, wrapping tension, angle and wrapping speed according to the wire diameter. No tape breakage or packet leakage should occur, and the surface of the insulated core after wrapping should be smooth and flat without mica falling off. When winding small cross-section wires, the mica tape is easy to fall off due to the small radius of curvature of the package. At the same time, the width of the mica tape is narrow and the tensile force is small. Therefore, the tension and speed of the package should be controlled uniformly to prevent the tape from breaking and falling. powder. The number of claddings and the lap ratio of mica tape vary depending on the material properties, specifications and models of cable products, and cable designers need to determine them based on the fire resistance test results. According to the IEC test standard for fire-resistant cables, we recommend wrapping around 2 layers with a lap rate of not less than 50%, that is, the wires are wrapped by 4 layers of mica tape.
