The insulation thickness of the power cord and the outer diameter of the wire should conform to the

Suitable for PVC power cords produced in the extrusion process.

2 Operators' self-inspection project requirements and methods (including semi-finished products and finished products)

2.1 Conductor structure and surface quality

2.1.1 Requirements: The conductor structure and the number of conductors should comply with the process regulations, the surface should be smooth, and there should be no defects such as warping, oxidation, and oil stains.

2.1.2 Inspection method: check the conductor structure and number of conductors by reading, and check the surface quality by visual inspection.

2.2 Insulation outer diameter and eccentricity

2.2.1 Requirements: The outer diameter of the insulation should meet the requirements of the process card, and there should be no obvious eccentric defects.

2.2.2 Inspection method: every head in the production should be inspected. Measure the outer diameter of the insulation with a 0-25mm outer micrometer with a scale of 0.01mm, and carefully check the eccentricity by visual inspection.

2.3 Surface quality of insulated wires

2.3.1 Requirement: The insulation should be squeezed strong, smooth and round, uniform in color, no particles on the surface, no pores in the section, serious defects such as thickness.

2.3.2 Inspection method: carefully inspect by visual inspection.

2.4 Sheath size and eccentricity

2.4.1 Requirements: The outer dimensions of the sheath should meet the requirements of the process card, and there should be no obvious eccentric defects.

2.4.2 Inspection method: every head in production should be inspected. Use an outer micrometer of 0-25mm and a scale of 0.01mm to measure the external dimensions, and carefully check the eccentricity by visual inspection.

2.5 Surface quality of sheath

2.5.1 The sheath should be squeezed to be strong, smooth and flat, uniform in color, no particles on the surface, no pores in the section, no serious thickness, no serious skewing.

2.5.2 Inspection method: carefully inspect by visual inspection.

2.6 Printing on the power cord plug

2.6.1 Requirements: The printing on the surface of wires and cables must be legible.

2.6.2 Inspection method: carefully inspect by visual inspection.

3 Inspectors' inspection item requirements and methods (including semi-finished products and finished products), power cord inspectors shall inspect according to 2.1~2.6.
