Investigation of falling behavior of communication cables from bundling hangers Part 3

Dynamic contact analysis of communication cable and spiral hanger against fluctuating wind loads

Abstract

Communication cables laid between utility poles are often bundled together with steel wires in a bundling hanger. Bundling hangers may be damaged at joints and communication cables may fall off the hanger due to a strong wind caused by a typhoon. This paper presents the behavior of the communication cable inside the hanger under buffeting by using a dynamic contact analysis for these componets against fluctuating wind load. The obtained results indicate that each componet inside the hanger is displaced integrally, thereby the communication cable press the hanger and cause the enhancement of sectional forces acting on the hanger.
