Characteristics：
1. Good anti-corrosion performance;
2. Material and structure are uniform, good resistance to vibration fatigue;
3. Short circuit current has small effect on the optical fiber transmission properties;
4. Good anti-lightning performance.
Description:
The PBT Loose Tube Optical Ground Wire (OPGW) is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.
Usually,there are 4 PBT loose tube inside the aluminum tube,each PBT loose tube 12 cores,this type of OPGW cable is widely used in South America,Africa and some old communication lines upgrading.
OPGW has two fiber type:one is single mode G652D and the other is G655,sometimes they mixed together,such like OPGW-36B1+12B4-93 [78.8;53.9]. Fiber optic cable OPGW, usually 12-48 fibers,ZR can produce max 96 fibers OPGW fiber optic cable, jelly filled and fiber contained central PBT loose/aluminum cladding steel/aluminum tube, outer with AA/ACS wires armored, detailed specification on your requests.
Typical Design for OPGW cable:
Specification | Fiber Count | Diameter(mm) | Weight (kg/km) | RTS(KN) | Short Circuit(KA2s) |
OPGW-113(87.9;176.9) | 48 | 14.8 | 600 | 70.1 | 33.9 |
OPGW-70（81; 41） | 24 | 12 | 500 | 81 | 41 |
OPGW-66(79;36) | 36 | 11.8 | 484 | 79 | 36 |
OPGW-77(72;36) | 36 | 12.7 | 503 | 72 | 67 |
