Considering construction difficulty, the existing methods are generally two, firstly, an independent cable platform is additionally arranged near a base tension pole tower of an original overhead line, and then a lead of the original overhead line is led to a cable terminal and a lightning arrester on the independent cable platform to realize the connection and the downward connection of a cable T; and secondly, cutting off the original overhead line at a proper position in a nearby straight line gear, newly building a base tension-resistant tower, additionally arranging a cable platform on the tension-resistant tower, and leading the original overhead line to a cable terminal and a lightning arrester on the cable platform to realize the downward connection of the cable T.
However, when the method is used, if the existing tension pole tower is far away from the newly built circuit power transmission line, the length of the cable line is increased, so that the construction cost is increased; meanwhile, an independent cable platform needs to be newly built near the existing tension-resistant tower to finish T-connection down of the cable, the independent cable platform cannot be far away from the tension-resistant tower, for example, ground facilities without influencing the construction of the platform near the tension-resistant tower can be built, and otherwise, the construction of the independent cable platform is difficult to realize.
