OPGW Cable Design
Fiber Optic Cable Construction
Overhead Fiber Optic Cables shall be OPGW (Optical Ground Wire). The OPGW cable is proposed to be installed on the transmission lines of the interconnection between new 30MW A.C. PV plant to EPGE 33KV substation, 12km apart

Transmission Line Details 
The transmission line is single circuit three phase line of size Pelican between the new PV Plant to EPGE/UTILITY Substation 12km apart. The normal 40ft pole shall be used for transmission line support.

Stainless Steel Loose Tube Type ①　Optical : Single mode optical fiber(SMF), multi mode optical fiber(MMF) ②　Filling compound : Jelly compound ③　Steel tube : Stainless steel tube ④　AS wire or Al ally : Aluminum clad steel wire or Aluminum alloy wire ⑤　AS wire or Al ally : Aluminum clad steel wire or Aluminum alloy wire ·Standard 6 to 144 fiber count ·Excellent crush resistance performance ·Maintenance data information system ·Power line protection ·Good resistance to strong winds, lightning and short circuit current

Non-metallic Loose Tube Type ①　Optical : Single mode optical fiber(SMF), multi mode optical fiber(MMF), Non-zero dispersion shifted optical fiber(NZ-DSF) ②　Loose tube : Thermoplastic material(polybutylene terephthalate) ③　Central member : Fiber reinforced plastic(FRP) ④　Filling compound : Jelly compound ⑤　Wrapping tape : Heat resistance tape ⑥　Al tube : Aluminum tube ⑦　AS wire or Al alloy : Aluminum clad steel wire or Al alloy wire ·Standard 6 to 144 fiber count ·Excellent crush resistance performance ·Maintenance data information system ·Power line protection ·Good resistance to strong winds, lightning and short circuit current

FDH(Fiber Distribution Hub) The FDH is designed and constructed to be suitable for outdoor installation. The housing is sufficiently sturdy to withstand typical handling and installation procedures. The design and layout of the cable guides promote an efficient and ordered positioning of the cable within the hub.
Joint Box Suitable for OPGW cable connection protection, has the function for direct connections and divergence connection, which can out of 4 cable, installed in the overhead pole, tower.
Clamp Clamps are used to guide OPGW cables from the top of the structure to the joint box or for grounding the cable. TFO provide proper spacing and holding strength without damaging the cable.
Tension Assembly Tension Assembly is used for OPGW cable route’s fixing and anchor shackling. Usually be installed on the terminal tower, tight tension tower and intersection angle tower etc.
Vibration Damper Vibration Dampers effectively reduce the level of Aeolian vibrations on OPGW cables. It respond to wind induced line vibrations that is characterized by high frequency, low amplitude motion.
OPGW(Optical Ground Wire) OPGW is a type of cable that is used in the construction of electric power transmission and distribution lines. Such cable combines the functions of grounding and communications. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire.
Suspension Assembly Suspension Assembles are designed for use with OPGW cable at suspension tower positions. Suspension Assemblies reduce static compressive stresses at the support point and cushion the OPGW cable against the dynamic stress of Aeolian vibration.
