Design of Optical Cable Joints for High Voltage Towers

Design of Optical Cable Joints for High Voltage Towers

The requirement includes the design, supply, stringing and splicing of OPGW cable on 400KV, 220KV & 132KV Transmission Towers. Prysmian has a built-in multi-step quality assurance programme, which covers the entire production process from cable design and raw materials purchasing, to final inspecti tion for any single project. Economical and easy to use, they have proven their value worldwide over many years in the installation of sub- stations, offshore applications and HV underground cables. Depending on design, OPGW (optical ground wire) ly designed for the spe-cial requirements of fiber optic overhead cables. The big advantages of this technology versus older technologies – like taping or field moulding - are the constant production. It deals with the factors that should be considered in determining the characteristics of this type of cable, the apparatus that should be used, the precautions that should be taken in handling the reels, and.
