PLAN No. 1224. UNDERGROUND CABLE SECTION—PLANT DEPARTMENT
This section has to do with installing, joining, and connecting telephone cables. Much of the work is splicing. Telephone cable consists of from 100 to 600 or more pairs of copper wire. Each wire is separated from its neighbors with a wrapping of paper or other insulating material. Then the bunch of conductors is covered by a protective sheath, usually of lead. In splicing, the lead sheath is first stripped from the end of the cable. Then the different corresponding pairs in the cables to be connected are joined together. Each joint is insulated with a paper sleeve slipped over it. When all of the pairs have been connected, a lead sleeve is slipped over the splice and “wiped” with hot solder to the lead sheath of the cables which have been joined. This work requires much skill and experience. Not only does the cableman splice the cables, but he must also connect them to the distributing frames in the central office and to the terminal boxes on the poles. A terminal box on the end of a cable is one whereby the aerial circuits are connected to the underground cable conductors. About the only way to become a proficient cable splicer is through experience as a cable splicer’s helper. This vocation should offer opportunities for men who have only minor disablements, and who should work out of doors nearly all of the time. The use of the hands and fingers is necessary. Cable splicers must sometimes climb poles. In very bad weather the cablemen are given indoor tasks. A cable splicer will ordinarily receive from $60 to $110 per month, and a helper from $40 to $85.
