<p>PURPOSE:To permit electric test effected in a short time and secure safe property by a method wherein one end of a charging cable is connected to a branch joint while the terminal end of the other end of the same is received in a terminal case and is fixed to the vicinity of the wall surface of an instrument. CONSTITUTION:A cable head is provided with a charging cable 14, connected to a cable line 13 through a bushing 11 receiving the terminal end of the cable line 13, a branch joint 20, provided near the bushing 11, and a terminal case 40, receiving the terminal end of the charging cable 14 and fixed to the vicinity of the wall surface 2 of an instrument. When a DC high voltage is impressed on the cable line 13 for example, the terminal case 40 is removed whereby test employing the charging cable 14 can be started immediately while the terminal end of the charging cable 14 is covered by the terminal case 40 after finishing the test and the case is fixed to the wall surface 2 of the instrument whereby the after treatment of the test is finished. According to this method, the electric test of the cable line 13 and the like can be effected a short time and the safe property of the cable head can be secured.</p> |
