Corner bar: In line with the change in direction of the place. Corner rod structure varies with the angle of the line: less than 15 degrees corner poles, may still bear bear together with the original horizontal angle; corner Buying telegraph poles in 15 degrees to 30 degrees, the two cross arm is available in corner force in the opposite direction of loading a cable; angle of 30 degrees to 45 degrees, in addition to double-cross arm, the sides of the jumper wire connecting the poles plant applications, the wire pulling in the opposite direction of the tube with a cable; corner at 45 degrees to 90 degrees, with two pairs constitute double cross arm on both sides with a jumper wire connection, while the wire in the opposite direction of the tube with a tension cable. Overhead line gear to be determined according to the distribution line voltage level, the wire-to-ground distance and terrain conditions. The larger span of rural poles, the fewer the number of poles, but in order to ensure a safe distance from the wire to the ground, poles have heightened. So high voltage distribution lines span generally: in town and village for 40 ~ 50m, in the field for 60 ~ 100m; low-voltage distribution lines when using aluminum hinge line, towns and villages in the span is usually 40 ~ 50m, in the field to 50 ~ 70m; file using insulated wire and low voltage distribution lines when distance is generally 30 ~ 40m, to a maximum of 50m. For high and low voltage distribution lines with pole erection, its span should meet the technical requirements of low-voltage lines.
