This standard applies to conductor cars which are used for driving (travelling) on conductors, shield wires or shield wires with integrated communication systems of overhead transmission lines.
This document applies to conductor cars that are used to access overhead line conductors, shield wires or shield wires with integrated communication systems to undertake work involving rectification of defects and/or installing components and fittings. This document covers also...
This PAS is a technical supplement to IEC 61156-1, edition 3 (2007): Multicore and symmetrical pair/quad cables for digital communications - Part 1: Generic specification. This PAS, covering exclusively four-pair data grade cables, is intended to provide a test method for the...
This standard consists of three distinctive scopes which have been subdivided between Modules A and B. • The scope of Module A covers technical requirements for Network Rail's Conductor Rail Heating system • The scope of Module B covers design and installation requirement for Network Rail's...
This specification applies to the design of guard boarding to be installed on both directly owned Network Rail infrastructure and to Network Rail facilities leased to a Train Operating Company. Where and what type of guard boarding is to be used is covered by NR/L3/ELP/27250. Purpose This document...
Aluminum electrical conductors today are being specified for nearly all new transmission lines and for most bare overhead distribution lines. Covered and insulated aluminum wire and cable have also been widely accepted; it is estimated that almost all new service drops and service...

Essa specifica le caratteristiche costruttive e le prove per il prodotto suddetto che ha lo scopo di consentire il transito sui conduttori di alta e altissima tensione. Questa Norma viene pubblicata dal CEI...
This standard applies to both maintenance and renewal activities for all conductor rail equipment, DC negative cables and associated components forming part of the electrical traction supply system. Purpose This standard holds the index for the conductor rail work instruction...
PURPOSE AND SCOPE This document forms part of a suite of documents, which define National Grid Transco's (NGT) functional and performance requirements for new plant and equipment. This specification covers the technical and general requirements applicable for designing a Conductor System...
The test methods and techniques used to measure the electrical characteristics of the grounding system include the following topics: a) Establishing safe testing conditions b) Measuring earth resistivity c) Measuring the power system frequency resistance or impedance of the ground system to remote...
Scope. This specification covers cables that have two parallel conductors that can be separated for any desired distance by tearing apart by hand.
This standard shall apply to all positive conductor rails forming part of the electrical distribution system. Purpose To define the minimum planned periodic maintenance that shall be carried out on positive conductor rail to ensure the safety of the electrical system.
This recommended practice establishes recommendations for three-conductor round and flat oil-well cables used in supplying three-phase ac electric power to submersible pump motors. The three major cables by components are as follows: a) Cables with copper...
3.1 The selection criteria is to be applied for uses of (1) new cable and (2) replacement cable. 3.2 For the selection of new cable or the selection of replacement cable, this practice defines the choice criteria for conductor selection for cables in AWG...
The standard describes a numerical method by which the core and surface temperatures of a bare stranded overhead conductor are related to the steady or time-varying electrical current and weather conditions. The method may also be used to determine the conductor current that...
This standard provides test method(s) and describes transfer (artifact) standards for characterizing electrical circuit probes and probes systems. The systems may include waveform acquisition hardware and software and signal/waveform analysis software. The probe includes the mechanism by which the...
The specification applies to all employers and people who undertake work on the DC Conductor Rail System and/or isolation work on Network Rail controlled infrastructure. This standard covers all top contact DC Conductor 3rd and 4th Rail Systems and DC maintenance depots. Purpose This...
The scope of this guide is to describe the effects and impacts of high temperature operation on conductors, connectors, and conductor hardware. The guide will identify operating metrics which constitute elevated temperature operation based on present industry practices and its effects...
