This standard provides calculated ratings for the following cables' Type 1: 600 V-5 kV unshielded extruded dielectric Type 2: 5-15 kV two conductor shielded URD single phase extruded dielectric Type 3: 5-46 kV single conductor extruded dielectric Type 4: 69-138 kV single conductor, unfilled, crosslinked polyethylene Type 5: 69-138 kV single conductor, filled crosslinked polyethylene and ethylene propylene rubber Type 6: 5 kV and 15 kV three conductor extruded dielectric Type 7: 5-35 kV single conductor paper insulated, lead sheathed Type 8: 5-35 kV, three conductor, paper insulated, lead sheathed, shielded Type 9: 69-500 kV, single conductor, self contained, paper insulated, liquid filled Type 10: 69 kV, three conductor, self-contained, paper insulated, liquid filled Type 11: 69-500 k V high pressure, paper insulated, liquid filled, pipe type Type 12: 115-500 kV high pressure, laminated paper, polypropylene insulated, liquid filled, pipe type Type 13: 69-138 kV high-pressure gas-filled, pipe type Installation conditions include duct banks (as shown in figure I), direct buried cables, cables buried in ducts, buried pipes, horizontal cable in ducts, in air and vertical non-vented riser cables. The various operating conditions for each of the cable designs and installation conditions are described in the technical features of the tables (clause 3).


Over the past 30 years the AlEE S-135-1 and S-135-2 (IpCEA P-46-426) Power Cable Ampacities publications have often been referred to as the "black books" and have been used by engineers, planners, and system designers throughout the world. During this time period, these publications were the only complete document on power cable ampacities in the United States. In 1976, the Insulated Conductors Committee, in cooperation with the Insulated Cables Engineering Association (ICEA) and the National Electrical Manufacturers Association (NEMA), published supplemental ampacity tables to provide ampacity ratings for single conductor cables with shield losses due to circulating currents. That publication was needed due to the tremendous increase in the use of single conductor extruded dielectric cables with multiple point bonding and grounding. As time passed, new cable designs were developed with synthetic insulation, different shielding designs and higher operating voltages and temperatures. Moreover, new technology and equipment was developed for measuring the thermal properties of soil. These developments with heat transfer in soils provided a different ,lnderstanding and approach for rating cables based on maximum cable/earth interface temperature. In addition, new forced convection heat transfer analytical methods were employed for cables in air, which provided for1ess conservative ampacity ratings. The tables in this standard reflect these changes in methodology and provide the user with a vast array of cable ampacity ratings for 600 V utilization cables, medium voltage distribution cable and high voltage transmission cables.


New IEEE Standard - Active. Over 3000 ampacity tables for extruded dielectric power cables rated through 138 kV and laminar dielectric power cables rated through 500 kV are provided.
