3411-2: Transmission Underground Cable Reference Manual - Chapter 2: Installation and Inspection

In most North American cities, underground power transmission depends on highly engineered cable systems capable of functioning reliably under extreme conditions during a lifetime of 50 or more years. The components that make up these cable systems are manufactured in specialized factories from highly refined materials, using precision equipment and subjected to rigorous quality control measures. Before shipment, all cables and accessories are tested to verify compliance with industry standards

Resiliency Resources Inventory

This Resiliency Resources Inventory is a compilation of resources across a sub-set of CEATI's transmission and distribution groups focused on enhancing the reliability and resilience of T&D systems. The inventory identifies ongoing and completed projects, as well as completed webinars, workshops and information exchanges showcasing innovations and best practices across multiple facets of power system resiliency. The inventory identifies resources on infrastructure hardening, grid moderniza

3417: Guide for Development of Business Cases for Replacement of Transmission Cable Assets

Many cities around the world experienced significant growth after the end of the Second World War. Utilities began rapidly installing underground transmission cables in major cities and urban areas to plan for future demand. Many of these first generation cables are still in service but will soon reach or exceed their expected design life. Since cable replacement costs are extremely high, utility engineers and asset managers are required to provide a detailed justification for these replacement

3416: Best Practices Guide to Underground Power Cable Real-Time Thermal Rating Systems

An application guide was commissioned by member utilities interested in practices for implementing real-time thermal ratings on underground transmission cables, consisting of extruded, self-contained fluid-filled and pipe-type systems. This report summarizes the results of an industry survey of TUCIG members and non-utility members, and describes the characteristics, application considerations, and summary of suppliers of these systems. The results show that real-time thermal ratings have been a

3414: Grounding and Bonding in Underground Cable Maintenance Work

Staff repairing High Voltage (HV) cables are subject to step and touch potentials arising from load and fault currents on parallel circuits. Also faults at terminating stations can be transferred along cables under repair where no parallel circuit is present. This report reviews the performance of existing grounding and bonding procedures. It recommends improved work practices and provides engineering guidelines to designers who specify cable configurations. The scope includes variations a

3411-3: Transmission Underground Cable Reference Manual - Chapter 3: XLPE Transmission Cable Design

Many North American power utilities are installing cross-linked polyethylene insulated cables when a new underground transmission is required. This type of cable system has replaced fluid-filled cables, which were formerly the most frequently specified type of underground transmission system. These cables, which are commonly referred to as XLPE cables, have very stringent requirements. However, the elimination of dependence on pressurization systems does reduce the complexity compared to fluid p

3405: Cable Health Index Software

The use of a cable health index is a significant development that enables condition information to be used in a consistent manner to assist with the end-of-life decision making process and to approximate expenditure expectations in future years. The Cable Health Asset Index Software is meant to simplify the implementation of index-based evaluation of cable assets by utilities, providing an easy-to-use graphical user interface and a fully accessible and modifiable database built upon the index it
