How are cables typically inspected for broken wires?

Cables are typically inspected for broken wires primarily through visual inspection. This method is effective because it allows inspectors to directly observe the external condition of the cable, including any visible signs of wear, fraying, or damage. Inspectors often look for irregularities in the insulation and conductors, which may indicate broken or compromised wires within the cable.

Visual inspection is a cost-effective and time-efficient method, making it suitable for routine checks and maintenance. While other methods, such as magnetic inspection, ultrasonic testing, and microscopic examination, can provide detailed insights into materials and structures, they are not as commonly used for general inspections of cables. Visual inspection serves as the initial assessment before more sophisticated techniques might be applied for deeper analysis or in cases where the visual check indicates possible issues.
