  Introduction to ADSS optical cable (at / PE) ADSS optical cable, all dielectric self supporting optical cable (also known as all dielectric self-supporting optical cable)
All dielectric, that is, the optical cable uses all dielectric materials
Self supporting refers to that the self reinforcing members of the optical cable can bear self weight and external load
This name points out the use environment and key technology of this kind of optical cable: because it is self-supporting, its mechanical strength is very important; All dielectric materials are used because the optical cable is in a high-voltage and strong current environment and must be able to withstand the influence of strong current
Precautions for optical cable erection and folding ⑴ during ADSS optical cable erection, attention must be paid to the problems, in which the of personnel is important, and various rules and regulations must be observed during construction
(2) as for fittings, the fittings required for installing ADSS optical cable include tension fittings for tension tower, suspension fittings for suspension, anti vibration whip, grounding wire and lead-down clamp, etc
The folding construction sequence shall first determine the tower number of each coil of optical cable, especially the tower number of the starting tower and the ending tower, and lay the traction rope and pulley on each tower, then place the tractor at the starting tower, and place the optical cable reel and tension machine at the ending tower
At the suspension point in the middle of the span, the pulley diameter shall not be less than 12 inches, and the pulley used at the beginning and end of the line shall not be less than 20 inches or 40 times the cable diameter in case of large changes in line conditions (such as 25 degrees or more in the horizontal or vertical direction)
Elastic rubber shall be used as buffer material in the pulley groove to reduce the wear of the outer sheath of the optical cable
The in wheel angle and out wheel angle of optical cable shall be less than 30 & deg;, The tension of the optical cable during laying shall be less than 1 ton, and the laying speed shall be 3-8 kilometers per hour
The optical cable and the traction rope shall be connected by a rotary compensation buckle to prevent the optical cable from being laid
