What are the advantages and disadvantages of overhead cables?

Advantages:hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Relative immunity to short circuits caused by external forces (wind, fallen branches), unless they abrade the insulation.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Can stand in close proximity to trees/buildings and will not generate sparks if touched.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Little to no tree trimming necessaryhPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Simpler installation, as crossbars and insulators are not required.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Ease of erection and stringing, less labor intensive, less construction resources needed.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

More aesthetically appealing.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Can be installed in a narrower right-of-way.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

At junction poles, insulating bridging wires are needed to connect non-insulated wires at either side. ABC can dispense with one of these splices.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Less risk of a neutral-only break from tree or vehicle damage, increasing safety with TNC-s systems.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Significantly improved safety for linespersons, particularly when working on live conductors.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Electricity theft is made harder, and more obvious to detect.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Less required maintenance and necessary inspections of lines.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Improved reliability in comparison with both bare conductor overhead systems and underground systems. Insulated conductors prevent accidental contact and supply can be maintained temporarily in the event of a suspension system collapse.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Disadvantages:hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Additional cost for the cable itself.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Insulation degrades due to sun exposure, though the critical insulation between the wires is somewhat shielded from the sun.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Shorter spans and more poles due to increased weight.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Can lead to much longer repair times for installations in hilly areas due to much higher line weights requiring bigger and more specialized equipment to repair.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Older installations are known to cause fires in areas where falling large trees or branches regularly cause breaks in lines and or in insulation leading to short circuits which can then lead to burning insulation dripping to ground and starting ground fires.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Failure modes through punctures, electrical tracking, and erosion.hPbPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri
