Abstract
An indefectible cable comprises a cable jacket with cable cores arranged in an inner cavity thereof and a metal ring sleeved on an outer wall thereof. Both ends of the cable jacket are fixedly connected with an anti-extrusion device respectively, through which the cable cores are led out from through-holes. The anti-extrusion device has a metal housing with plastic lining. With the arrangement of a buffer device, the externally applied pressure on the cable is relieved to reduce the damage thereof.
