NCR 2331 FIRST INTERIM REPORT Description of Deficiency TVA construction specification 0-38 requires a minimum bend radius of no less than 19.6 inches for 8kV power cables to prevent overstressing the cable insulation. Some of the cable tray fittings used at Bellefonte require an installed cable bend radius as short as 7 inches.
Interim Progress TVA is contacting the vendor to provide assistance in determining if a 7-inch bend radius will permit acceptable cable performance.
