The correlation between the breakdown of the cushion layer and the quality of the steel strip is mainly reflected in the fact that defects such as burrs and curled edges on the surface of the steel strip can puncture the cushion layer, leading to insulation performance failure.The specific associations and solutions are as follows:

correlation reason

1. Burrs and curled edgesDuring the production or processing of steel strips, improper edge treatment may result in burrs or curled edges. These sharp or uneven parts are prone to puncture the cushion layer and damage the insulation structure during cable assembly or use.

2. Insufficient thickness of steel stripWhen the thickness of the steel strip does not meet the design requirements, its mechanical strength may be insufficient to effectively protect the cushion layer from external pressure or damage, indirectly leading to the breakdown of the cushion layer.

3. Material issue of steel stripPoor steel strip material, such as impurities or uneven internal structure, may reduce its corrosion resistance and mechanical properties, thereby affecting the long-term stability of the cushion layer.

solution measures

1. Strict quality inspection of steel strip：

   • Inspect the appearance of the steel strip to ensure that there are no defects such as burrs or curled edges.

   • Measure the thickness of the steel strip using tools such as calipers to ensure compliance with design requirements.

   • Conduct material analysis on the steel strip to ensure its chemical composition and mechanical properties meet the standards.

2. Optimize cushion design：

   • Choose plastic tape with high hardness and good puncture resistance as the cushion material.

   • Increase the thickness of the cushion layer to enhance its ability to withstand external pressure.

3. Improve production process：

   • In the process of steel strip processing, advanced edge treatment technology is adopted to reduce the generation of burrs and curled edges.

   • Optimize the cable assembly process to ensure a tight fit between the steel strip and the cushion layer, avoiding gaps and misalignment.

4. Strengthen the management of semi-finished products：

   • Strictly inspect the quality of semi-finished cables to prevent damage to the cushion layer caused by bumps, scratches, etc.

   • During storage and transportation, protective measures should be taken to avoid mechanical damage to the cables.
