The aim is to reproduce the working conditions. Crush test This test allows to compress in a transverse direction a cable section between a base, formed by a plane horizontal steel plate and a mobile one, where an even force is applied on a cable section. Do you need a multi-user copy? Torsion test The test is carried out on a cable sample anchored to a fixed support and to a rotating support and by applying a sample load. The aim of the test is to verify the behaviour after the percussion of the cable and of the fibres.

The aim of the test is to verify the behaviour after the percussion of the cable and of the fibres. The following test report forms are related: Impact test The tests consists in vertically dropping down a certain weight on an intermediate section made of steel that is meant to transmit the percussion to the cable sample.

Mechanical tests on fibre optic cables
New range of heat-detector cables. Figure 8 aerial cables are also excluded; they are specified in IEC This edition includes the following significant technical changes with respect to the previous edition: The cable does not contain metallic components.
The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
The ADSS cable consists iex single mode optical fibres contained in one or more protective dielectric fibre optic units surrounded by or attached to suitable dielectric strength members and sheaths. Torsion test The test is carried out on a cable sample anchored to a fixed support and to a rotating support and by applying a sample load.
The cable undergoes clockwise and anti-clockwise rotations. Crush test This test allows to compress in a transverse direction a cable section between a base, formed by a plane horizontal steel plate and a mobile one, where an even force is applied on a cable section. Requirements of the sectional specification IEC for aerial optical cables along electrical power lines are applicable to cables covered by this document. Look inside Relevant for fibre optics.

Tensile performance This test is meant to evaluate the elongation of the cable which is subject to an increasing traction load, thus monitoring at the same time the attenuation variation. An ADSS cable is designed to meet the optical and mechanical requirements under different installation, operating and environmental conditions and loadings, as described in Annex B. Preview Abstract IEC The aim is to verify the behaviour of the cable and the fibres that are subject ie a compression.

This document provides construction and performance requirements that ensure, within the guidelines of this document, that the required mechanical integrity of the cable components as well as optical fibre mechanical reliability and transmission parameters are maintained. The cables can also be used in other overhead utility networks, such as for telephony or TV services.
Applications Application areas Reference list.
This document covers the iex, mechanical, electrical, and optical performance, installation guidelines, acceptance criteria, test requirements, environmental considerations, and accessories compatibility for an all dielectric, self-supporting fibre optic ADSS cable.
The lack of any liquid traces on the cable end determines the positive result of the test. This second edition cancels and replaces the first edition published in and constitutes a technical revision. Cavicel has expanded its range of heat detector cables HDC.
