HPFF & HPGF Cable Systems - Design, Installation, Operation
This course focuses on the design, ampacity, specification, installation, uprating, maintenance practices, dielectric fluid-handling systems, and life evaluation of both high-pressure gas-filled (HPGF) cables and high-pressure fluid-filled (HPFF) cables. There are extensive slide presentations on cable manufacturing and pipe and cable installation. Topics include ampacity calculations, cathodic protection systems, pumping plant requirements, dissolved gas analysis (DGA), cable ampacity, uprating methods using fluid circulation and forced-cooling, relocation and extension of existing lines, and many other topics relevant to pipe-type cables including several presentations on state-of-the-art trenchless water crossings. Enhanced to include more analytical calculations!

Extruded Dielectric Power Cable Systems - Design, Installation, OperationExtruded-dielectric cables are now in service through 500 kV worldwide, and there are extensive installations in the United States at 345 kV. We will discuss design aspects, including analytical studies, installation considerations, factory and commissioning tests, general operation considerations, utility power system effects, and maintenance practices, focusing on XLPE-insulated cables as well as EPR-insulated cables. There will be special discussions of hybrid lines, where short sections of UG cables may be the only way a utility can permit a long OH line, as well as reconductoring existing pipes with XLPE or EPR cables. There will also be special discussions on HVDC cable systems and Submarine cable systems. Enhanced to include more analytical calculations!

Power Cable Ratings and Soil ConsiderationsUnderground cable systems generally have lower ratings than overhead lines, and the cost per ampere is much higher. In addition to traditional underground T&D systems, wind farms are using underground cables to collect power from distributed wind generation. From the standpoint of ratings, both over-designing and under-designing are very costly, so it is desirable to confidently rate the cables near their ultimate limit. Important issues include:
♦ Ampacity audits and uprating ♦ Soil dry-out - is it really an issue? ♦ Shield/sheath bonding of extruded cables ♦ Fluidized Thermal Backfill™, other fills ♦ Conductor size vs. additional special backfill ♦ Temperature monitoring; dynamic rating Dr. George Anders will speak on special topics, e.g.: ♦ Effects of cable crossings ♦ Deep cable ampacities ♦ Cables in tunnels ♦ Wind farms and Data Centers ♦ Other special topics selected by students September 22-25, 2025 $3100 2.8 CEU's Location: Richmond, Virginia |
