Heavy machinery is indeed a primary concern when it comes to cable damage and potential outages. This equipment often operates in environments where cables are installed, such as construction sites or areas where ground excavation is occurring. The size and weight of heavy machinery can easily crush, cut, or sever cables, leading to service interruptions.

In addition, the presence of heavy machinery can cause additional issues, such as vibrations and movement that might disturb cable installations, particularly if they are not buried deeply enough or protected adequately. Disruptions caused by heavy machinery typically require immediate attention to repair the damaged cables, reinstating service and avoiding extensive downtime.

The other types of equipment listed generally do not cause physical damage to cables. Signal amplifiers, leakage detectors, and power supplies are mostly electronic components that enhance or maintain signals and power in existing systems rather than interact with the physical installation of cables in a damaging manner.
