Abstract: A modular cable protector assembly has side ramps, tunnel members, and tunnel connectors that can be removably engaged to one another in a modular fashion to form a wide variety of configurations. Each tunnel member includes a tunnel extending along its length for passage of cables, and two sets of laterally-opposed connectors that removably engage corresponding connectors on the undersides of the side ramps. Each tunnel connector has two sets of connectors that removably engage the connectors on two tunnel members and thereby secure the tunnel members in a side-by-side relationship. The side ramps and the top surface of the tunnel connector combine to provide a relatively continuous surface over the cable protector assembly that is suitable for foot traffic or wheeled traffic.

Abstract: A moisture barrier is molded and/or glued around an exposed section of a conductor where a surrounding insulation layer is removed.
