,g 0;N hus A ' ! i m i Subj: ANO Tape Splice Test, Infonnation Received from Okonite Re'gnding Thennal Propenies of Okonite T-95 Splicing Tape Date June 19,1990 At 1600 MLEA ( J. A. Murphy & C. J. Crane) called Okorute (Tim Fitzgerald)to determine if he had anj further information on the thermal aging problem described to him.this morning. He stated that he had a panial answer and provide the following information:
- T-95 splice tape is an uncured material (i.e. no peroxide was added to the compound).
T 95 splice tape will melt at 150 *C because it is uncured.
In the NORN-3 test, the T-95 splice ta ae was over and in line splice and was completely encapsulated by the No. 35 jacxeting tape.
- Okonite has been telling utilities for years that T-95 splice tape should not be used for bolted V splices without a No. 35 jacket.
- The Okonite laboratory told him it was not necessary to put a roll of T-95 tape in the thermat aging oven because it would definitely melt, s
MLi.A asked him it there was a known maximum temperature at which the T-95 tape would
~
not melt. He stated that he would check with the engineer who was involved with all of the
- T.95 testing and let us know tomorrow morning. He was asked if he would confirm what he had told us in a letter (including the maximum temperature at which melting would not occur. He stated that he would do th. t by explaining in detail what the NORN 3 testing means.
