3402: Guide for the Selection of AC Transmission Underground Cable Systems

The selection of optimum transmission cable systems with respect to technical, economical andenvironmental considerations is usually a complex decision. This guide facilitates that selectionprocess for underground transmission cables.This guide contains two main parts. The first part describes the methodology of the selectionprocess, consisting of three different steps including the assessment of conditions and the selectionof a cable type. The second part of the document provides relevant infor

3406A: Acceptable Vibration Limits and Forces in the Vicinity of Underground Cables, Phase I

The purpose of this project was to develop a methodology to determine acceptable vibration levels when performing construction work in close proximity to various types of underground transmission cables. In addition to vibrations near construction sites, the influence of traffic vibrations on cables and vibrations in cables installed on steep slopes were also investigated. In this first phase of the project, a literature search was undertaken. This report lists and summarizes the published infor

3410: Reliably Predicting Underground Cable Life from Endurance and Breakdown Tests

The primary objective of this study was to develop an electrical aging model for XLPE cables aged at room temperature in air. A model successfully describing various experimental results on films and cables is presented within this report. The basic parameters involved in the model are explained, and difficulties associated with data interpretation are discussed. Another objective was to relate breakdown and electrical aging. It is shown that there is indeed a relation between the two processes,

3420: HPFF Joint Casings Corrosion Protection Aging Test

High-pressure fluid-filled (HPFF) cables are the most widely used pipe-type electrical transmission line, accounting for 80% of all underground transmission lines [1-4]. Corrosion is a primarily concern for pipe-type cable systems, specifically regarding the cable pipe. Steel pipelines can corrode if they come into contact with water and salts in the soil. If the surface of the pipeline is damaged, corrosion is likely to occur, resulting in the leak of the fluid contained between the pipeline an

3422: Review of CEATI Health Index Rating and Weighting System

A workshop on cable asset health indices was conducted at the 2018 Transmission Underground Cable Interest Group (TUCIG) spring meeting in San Diego. This forum provided an opportunity for a wide-ranging discussion among TUCIG members on methods currently used for asset health determination, protocol details and technique effectiveness. Three participants presented on different methodologies currently being used within their respective utilities. These presentations described very different appl

3427: Guide for Retrofitting HPFF Cable Pipes with XLPE cables

This guide provides member utilities with information about converting conventional pipe-type cable circuits to utilize cross-linked polyethylene (XLPE)-insulated cable, effectively converting the “pipe-type” circuit(s) to “XLPE in steel casing” circuit(s). The guide focuses on the planning and design considerations relevant for retrofitting XLPE into cable pipe, which include retrofit technology options, evaluating circuits that may be considered for conversion, rating challenges as a result of

3418B: Submarine Cable Route Maintenance, Revised

Increasing global energy requirements, combined with the growing integration of renewable energy power sources (both marine and terrestrial), have led to a significant rise in the installation of submarine transmission cables to distribute power within and between countries, spanning seas, estuaries, rivers and lakes. To the asset owner and network operator, reliability and availability of the cable to provide power transmission capacity to the network is paramount. A structured approach to cabl

3415: Manhole Entry Safety Practices and Technology

This report documents a range of hazards associated with utility work in confined spaces that contain energized transmission cables. The report has been prepared in response to concerns expressed by members of the Transmission Underground Cable Interest Group (TUCIG) regarding hazard management in these situations. The objective of the report is to identify the major risk factors for workers entering confined spaces containing energized transmission cables using published information on the reli

3423: Advanced Cable Diagnostic Test Techniques for XLPE, HPFF and LPFF Cable Systems

There are several test techniques offered in the industry for evaluating high voltage (HV) cable systems. There have been presentations made at technical meetings organized by the IEEE Insulated Conductor Committee (ICC) and CIGRE regarding the field testing and diagnostics of HV cables.Some of the diagnostic test techniques are relatively new to the industry and have not necessarily been verified for suitability. This project was undertaken to highlight the different types of diagnostic tests a

3411-1: Transmission Underground Cable Reference Manual - Chapter 1: Maintenance

The information used in the preparation of this Manual already existed in various formats within the member utilities. Individual utilities had generally organized their practices in an ad hoc manner, corresponding to their own specific system needs. Since transmission cable systems have always been custom engineered to meet the specific utility requirements, there are a considerable number of variations in the procedures followed by the individual utilities.
