Abstract
Design of a termination for 4-kv operation on PILC cable has been described. It is based on a hand applied insulation and weather seal of epoxy-resin-impregnated orlon tape which covers the cable end from the lead sheath to the high-voltage connector. Filler materials may be added to the basic resin. Savings have been effected through the elimination of the porcelain pothead or, alternatively, through the use of paperinsulated cable throughout rather than a length of rubber-insulated cable joined to the paper-insulated cable for the terminal section. The termination successfully passed the AIEE pothead design tests, and tests described herein have further shown the adequacy of the bond between the epoxy resin-orlon wrappings and copper and lead. Previous tests1 have demonstrated the resistance of the epoxy resin-orlon wrapping to moisture penetration. Service installations have already successfully withstood the extremes of summer and winter weather. Accelerated outdoor aging tests are in progress to provide additional data on the weathering ability of the terminations. The epoxy resin-orlon termination is now standard for use on PILC cable indoors in the Baltimore Gas and Electric Company's 4-kv system and is used at selected locations out of doors.
