Round Cable Fastening Solutions for Overhead Lines
Release time: 2024-12-31
Enabling the roll-out of outside plant ultrafast broadband networks on MV, LV or telecommunications networks, ADSS (All Dielectric Self-Supported) cables are effective solutions for the transmission and distribution of optical signal. Their main benefit consists in their design: ADSS cables are developed with a reduced diameter and they offer a low overall weight. This makes it possible to relieve poles and thus to permanently preserve the operated infrastructure. In addition, the non-metallic structure of ADSS cables provides an anti-lightening protection, eliminating thus the risk of network failure caused by natural hazards. Depending on their structure and the manufacturer's specifications, ADSS cables are used for deploying a telecom network segment in overhead or underground configurations, for indoor installation or, in case of multi-function ADSS cables, for a discontinuous installation implying outdoor-indoor or overhead-underground transitions. In that respect, ADSS cables with loose tube structure are notably used for the deployment of feeder networks. Micro-bundle or cables with a stranded structure are preferred instead for the rollout of distribution networks as they offer an increased flexibility and an easier access to the fibre. In order to guarantee future-proof overhead lines rolled out by using ADSS cables, it is essential to pay a particular attention to dead-ending and suspension clamps. Together with the cable, these accessories form a cohesive unit. Hence, they must meet compatibility criteria. Here are the main elements to check before selecting the right AC ADSS clamp or the most suitable suspension device for your cable: ㆍthe outer sheath diameter ㆍthe maximum allowable tension, also called tensile load short-term ㆍthe minimum bend radius ㆍclimatic conditions specific to the installation environment
