Abstract: A new insulation shield compound has been developed, which exhibits strip force of less than 10 pounds per half inch on XLPE and TRXLPE insulated MV cables, and is very uniform as a function of temperature. As a consequence of cleanliness improvements, the peeled interface with XLPE/TRXLPE is very clean and essentially free of conductive debris larger than 25 microns. Strip force retention after AEIC dry cyclic aging of MV cables meets ICEA requirements
Abstract: What is meant by the term "Conventional Furnace Black"? Although morphological parameters have remained constant, product quality (physical and chemical purity) has improved significantly over the years to better serve the industry. In comparing cable life data it is important to keep in mind the "vintage" of the carbon black used in the conductor shield.
Samples of a widely used conventional furnace black from 1971 to 1997 were tested for a number of properties related to product quality. Results will be compared against acetylene black and extra-clean furnace black.
Abstract: ABB and Hydro-Quebec have developed a solid insulation distribution transformer (SIDT) in ratings up to 500 KVA, 14.4 KV, 125 KV-BIL. It is suited for buried vault and vault-less construction. The insulation is moisture impervious. The non-metallic construction is free from corrosion. The elimination of oil results in a non-explosive failure mode and environmentally friendly construction materials.
The insulated conductor with termination components mounted in the typical URD pad mounted transformer are proposed for installation in a shallow sub-surface elbow switching and secondary service and fusing compartment. This then would form the basis for a total underground construction for URD.
