<p>PURPOSE: To make it unnecessary to use a pit, etc., for drawing a lead cable into the air and holding it, by providing an L-shaped bushing for connecting a conductor drawing bar electrically with the lead cable provided horizontally and linearly toward an apparatus, at the base part of a cable head supported on a stand. CONSTITUTION: To the base part of a cable head 10 supported on a stand 9, an L-shaped bushing 2 for connecting a conductor drawing bar electrically with a lead cable 3 provided horizontally and lenearly toward an apparatus 21 is fitted. Besides, the other end of the lead cable 3 is connected on the upper surface of the apparatus 21 electrically to a receiving terminal 22 of L-shaped structure. Consequently, a pit, manhole, etc., for holding a lead cable become needless, and it becomes possible to shorten the time of construction and to save labor.</p> |
