Abstract

Push-cables and associated apparatus for pipe inspection systems are disclosed. In one embodiment a pipe inspection system includes a camera head, a push-cable including an outer covering enclosing a plurality of electrical conductors for transmitting signals and/or power between the camera head and an electronic device operatively coupled to the push-cable, and a spring assembly disposed about the push-cable near the distal end where the spring assembly comprises a spring with a tapered flex section having a varying cross-sectional area and/or a varying cross-sectional shape.
