This winding should be extended close upto the end of the sheath. This is to prevent paraffin applied inthe next operation from following along the core of the cable withinthe sheath. The next operation is to dip the end of the cable so prepared inhot paraffin, which must be heated above 212 degrees F. Thecable ends should be held thus immersed until all bubbling ceases,when they should be taken off. This preliminary boiling out isto prevent moisture from getting into the cable while splicing, andshould extend well over the cotton wrapping already FIG. 601.—CABLE SPLICING.
