Practice of Use T Cross Arm to Increase the Distance of Lines
With the development of the scale of wind power generation,more and more tower are used which has multicircuit transmission lines on it, the same to T connection line. In general, the minimum distance of lines are satisfactory when T connection line is single line, but unsatisfactory in multi-line for the change of the conductor spatial arrangement. There are three solutions round this: add a converted tower,extend the cross arm,add T cross arm. Through the contrast of the feasibility and the economy of these solutions, it is proof that the minimum distance of lines can be satisfactory when use the solution of add T cross arm,and when the T connection line is double line.
