The utility model relates to a cable terminal platform on a power transmission line iron tower. The utility model relates to a cable terminal platform, in particular to a split self-standing angle steel pipe combined cable terminal platform. The key points of the structure are that: the structure is simple, the system comprises two sub-terminal platforms. Wherein the sub-terminal platforms are respectively and independently arranged at two sides of a terminal iron tower, each sub-terminal platform comprises a plurality of upright posts and an integral platform structure surface arranged on theupper end surfaces of the plurality of upright posts, a plurality of cable terminals and lightning arresters are arranged on the platform structure surface, and one to two overhaul crawling ladders are arranged at one side edge of the platform structure surface. The utility model has the advantages that: firstly, the cable terminal platform and the terminal iron tower are completely separated from each other, are independent from each other and do not influence each other; in addition, the stability and reliability of the cable terminal platform structure are ensured, the construction efficiency is improved, and overhaul and maintenance are facilitated.
