TEST VOLTAGE CHARGING METHOD OF BOTH END APPARATUS DIRECT-COUPLED CABLE

PURPOSE:To obtain a test voltage charging method of a both end apparatus direct-coupled cable which can be applied to a slip-on type apparatus, too, consists of a simple and small-sized constitution and is capable of charging easily to a testing cable, by providing a charging branch on the end or the middle of a line. CONSTITUTION:A Y-type branch 23a is provided in a terminal box 20 of an apparatus case 21, and when a blanking cover 32 is removed and a moving cable 35 is connected directly to the branch 23a, a cable to be tested 27 is charged through the cable 35, and the cable 27 is tested. When the branch is provided in the middle of a line, the charging can be executed in the same way. It this way, it is possible to obtain a test voltage charging method of a both end apparatus direct-coupled cable which consists of a simple and small-sized constitution, can be applied to a slip-on type apparatus, too, and is capable of charging easily to a testing cable.
