Overhanging line clamp

OPGW overhang clamp installation, should be vertical ground plane, along the line direction and the vertical position of the offset Angle shall not be greater than 5°, and the offset shall not exceed 80mm, continuous on the hillside tower on the installation position of the overhang clamp should meet the requirements.

The overhanging wire clips the ground lead

OPGW overhanging series of ground leads should be naturally drawn, the lead is naturally smooth, and the installation position of the whole line should be unified. The direction of the grounding and connecting trench clip shall not be twisted, vertical or horizontal. The center of the wire bar should coincide with the mark. The winding of the wire bar should ensure that both ends are neat. The winding direction should be consistent with the twisting direction of the outer wire strand, and the original pre-twisting shape should be maintained. The rubber pad in the cable overhanging clip should be arranged up and down.

Tension clamp (connector type) ground lead

OPGW joint type tensile string joint lead down to natural, smooth, beautiful. The ground lead should be installed in the same position. The ground lead should be natural and smooth. The direction of the grounding and connecting trench clip shall not be twisted, vertical or horizontal. When wrapping the prestranded wire, ensure that both ends are neat and the direction of wrapping is consistent with that of the outer strand, and keep the original shape of the prestranded wire. Tensioned prestranded wire shall not be reused more than twice.

Tension clamp (straight through type) ground lead

OPGW joint type tensile string joint lead down to natural, smooth, beautiful. The ground lead should be installed in the same position. The ground lead should be natural and smooth. The direction of the grounding and connecting trench clip shall not be twisted, vertical or horizontal. When wrapping the prestranded wire, ensure that both ends are neat and the direction of wrapping is consistent with that of the outer strand, and keep the original shape of the prestranded wire. Tensioned prestranded wire shall not be reused more than twice.

Lead down

OPGW lead down from the inner side of the tower main material, bending radius should not be less than 40 times the diameter of the cable. The lead down line shall be fixed on the protruding part of the tower material with a fixture. Friction and collision between the remaining cable and the Angle iron shall not occur. The installation distance shall be within the range of 1.5 ~ 2m. The lead line should be natural and smooth, and the lead line between the two fixed fixtures should be tightened.

Cable rack installation

Cable tray installation: cable winding should be orderly, not cross and twisted force, binding point is not less than 4, each cable tray should not be less than the cable to the ground plus 5m. The cable rack is fixed in the proper position on the inside of the tower with special fixtures. The leads other than the rest cable frame should be fixed with lead down clips to prevent wind blowing.

Junction box installation

The OPGW terminal box should be installed in the position suitable for the tower. The installation height should be 8 ~ 10m, and the installation position should be the same for all lines. Reliable and fixed installation, no loose, waterproof sealing measures are good. The inlet and outlet cables of the junction box should be smooth and smooth, and the bending radius should not be less than 40 times the cable diameter.
