This document compares overhead high voltage systems (OHS) and underground cable systems (UGCS) and discusses cable jointing and termination procedures. It outlines the key steps for jointing and terminating cables using different methods like heat shrinkable, cold shrinkable, push-on, and cast iron joints. The procedures for heat shrinkable and push-on cable terminations are described in detail.
