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. Good anti-corrosion performance.Material and structure are uniform, good resistance to vibration fatigue.
Characteristics
● Stainless steel tubes filled with hydrophobic gel provide the protection and support of the optical fibres
● Accurate process control ensures good mechanical and temperature performances
● Larger diameter, larger fibre count
● Stable structure and high reliability
● High tensile strength and large short time current capacity to reach optimum balance of mechanical and electrical properties
