Product Parameters

220KV double circuit transmission tower, two earth wire at top tower peak, and its cross-arm only at both side of tower with longer loading design. This J1 double loop tension tower is based on the J2, the ground wire and the wire cross-arm are changed to the left and right equal length, that is to say, the left and right cross-arm are processed  with section number from tower body.
