Product Parameters
In power transmission & distribution project, sometimes we need multitude circuit to transfer more power current. Then this condition force we create multi circuit and strict power line, which adopt multi circuit tower. The multi circuit tower can effectively reduce the corridors for overhead transmission line and the occupied lands; it had good economic and social benefits. We provide every type of 69KV seven circuit steel tower for our clients, which is widely used in city or rural power transmission and distribution.
