Method for butt-end electromechanical splicing

摘要

A process and system for repairing electromechanical cables having an external armor wire layer using a butt welding technique and an arc vanishing machine. A short (break) in a cable having both an external and inner helically wrapped wire layer over an inner conductor(s) is located using conventional techniques. After the inner conductor(s) and inner wrapped layer are repaired (i.e., spliced), the outer wire layers are reconnected using a butt-end welding process and form individual arc shapes. The cable automatically passes through dies on headers to vanish (displace) each of the arcs to the end of the cable. A safety system activates an alarm to shut down the system when a jam occurs before any cable wires break. The system is reactivated after the jam is cleared.
