The subject underground cable assembly protection system of this invention relates to a plurality of rigid substantially impact-resistant elongate protective channel members. Each of these channel members defines an enclosed compartment for housing the cable assembly. The system of the present invention also includes means for interconnecting adjoining channel members to each other. In this way, the underground cable assembly protection system can be formed. The channel member and/or the interconnecting means can comprise a polymeric material, and more preferably an impact-resistant polymeric material such as high-impact PVC or polyurethane. The channel member and/or the interconnecting means can comprise a substantially U-shaped cross-sectional configuration, more preferably the substantially U-shaped cross-sectional configuration of each the channel member comprises a horizonal base section having a pair of respective ends and a pair side sections attached to the pair of respective ends of the horizonal base section.
