【摘要】 采用击倒法和实验群体法测定电缆护套层抗白蚁蛀蚀性能。结果表明，YJLW02－Z型电力电缆的护套层抗白蚁蛀蚀性能达到GB2951．38—86国家标准中对聚氯乙烯护套层材料的要求，护套层试片对台湾乳白蚁工蚁的KT₅₀334．3±3．3分钟，台湾乳白蚁群体对护套层试片的蛀蚀等级力1级。更多还原

【Abstract】 time and colony test methods from “termite test methods for wires and cables”(GB2951 .38-86, issued by the Standard Bureau, People’s Republic of China) were used to test KT50 and damage class of the coat layer (PVC & contain temiticide Chlordane) of YJLW 02-Z type power cable to attack by Coptotermes formosanus - The results indicated that the coat laye of powr cable has strong ability against attaking by C .formosanous colony and reaches the zeopests of GB 2951. 38 86. KT50 of the coat laye to C.fro- workers is 334-3 ±3.3 minutes. The damage class of the coat layer to attack by C formosanus is only class 1更多还原
