Abstract
Abstract A cable end connection to a loading coil case has a lead sleeve crimped over the cable end, with a layer of sealing compound between the lead sleeve and the outer protective sheathing of the cable. The metal sheath of the cable is exposed at the cable end by removal of the protective sheathing for a short distance and the end of the lead sleeve is soldered to the metal sheathing. A tube extending from the end of the loading coil case is a close fit over the lead sheath, the outer end of the tube soldered to the lead sheath.
