e e I. When placing ADSS, all precautions and safety requirements of the respective company shall be followed. When required, use of warning signs and traffic warning cones shall clearly define the work area to safely channel the traffic. On streets or highways, always place the cable in the same direction as the traffic flow and use flag-men to control traffic. 2. Do not allow the cable to twist as it is pulled through travelers or sheaves. If continuous twist in a constant direction is observed, stop the installation immediately, ease off the tension, and readjust to traveler. Due to the light weight of ADSS in relation to most sheaves, and the relative low stringing tensions used during installations, the traveler will require support at the base to help prevent the cable from riding out of the traveler or prevent excessive twisting during installation. 3. Do not sag/tension the cable around heavy angles. . 4. Always sag/tension the cable from dead end segment to dead end segment. 5. The contractor is responsible for selection ofattachrnent position of the ADSS cable. 6. The contractor is responsible to prevent dangerous scintillation's. 7. The contractor is responsible to maintain the separation and clearance requirements at the attachment points of"the cable. ' 8. ADSS fiber optic cable is specifically covered in the 1997 NESC(National Electrical Safety Code). ADSS cable is meeting Rule 230Flb. 9. If the ADSS fiber is defined as a communication conductor located in the communications space, the clearance rules are as follows: · ADSS from Effectively grounded neutrals =40 in. · ADSS from Supply conductors 0 to 8.7kV =40 in. · ADSS from Supply conductors 8.7 to 50. KV =40 in. plus 4 in. per kV above 8.7kV 10. If the ADSS fiber is defined as a communication conductor, located in the supply space the clearance rules are as follows: · ADSS from Effectively grounded neutrals =Note I and 2 · ADSS from Supply conductors 0 to 8.7kV =Note 2 · ADSS from Supply conductors 8.7 to 50. KV =Note 2 Note I: No clearance is specified between neutral conductors meeting Rule 230E I and installed communications cables located in the supply space and supported by an effectively grounded messenger. Note 2: No clearance is specified between fiber-optic supply cable mee~ing Rule 230F I b supply cables and conductors. 1. If the ADSS cable is defined as "communication" or "supply" then minimum ground clearance shall be as follows: · ADSS cables from "Railroad Track" =23.5 feet · ADSS cables from "Streets, Other Truck Traffic Areas" = 15.5 feet · ADSS cables from "Driveway, Parking Lot, Alleys" = 15.5 feet · ADSS cables from "Pedestrian Traffic Areas" = 9.5 feet · ADSS cables from "Water Areas- Not Suitable for Sailing" =14.0 feet IBM Global Sen'ices &: La Porte ISO peA 01 September 30.1998 Page 26 of 32
