Cable made with Dow HFDA-0587 BK, HFDB-4202 EC, and HFDA-0693 BK was found to meet DL/T 1070-2007 requirement of tree retardant XLPE (TR-XLPE) power cable. The alternate-current breakdown(ACBD) value after 360 days of accelerated water treeing test (AWTT) was 29 kV/mm, which exceeds the DL/T 1070-2007 requirement of at least 20 kV/mm. Cable made with semiconductive shield materials from other material suppliers and HFDB-4202 EC, however, failed to meet DL/T 1070-2007 requirement of at least 20 kV/mm after 360 days of AWTT. This failure to meet DL/T 1070-2007 requirement, apparently, was caused by the high content of ionic contaminants and ash levels in the semieonductive shield materials. The results in this report suggest the use of clean semiconductive shield materials is necessary, in conjunction with tree retardant insulation material, for cables to meet the higher performance TR-XLPE DL/T 1070-2007 requirement, which will enhance system reliability by ex-tending cable life, while lowering life cycle costs.
