In the communication industry, both ADSS optical cables and OPGW optical cables have been widely applied. Since the advent of optical cables, they have immediately attracted great interest from the power sector. Many power departments have now become new telecommunications operators because they possess tower resources. For both ADSS optical cables and OPGW optical cables, long-term usability is required. The materials used must be of high quality and must be produced by正规 manufacturers.

1. Different Structures.

OPGW optical cables mainly consist of a cable core (fiber unit) containing optical fibers and metal strands (including aluminum-clad steel wires, galvanized steel wires, aluminum alloy wires, hard aluminum wires). So far, hundreds of different structures have emerged, mainly falling into three types.

Aluminum tube type. Frame aluminum. Tube type. Steel tube type.

ADSS optical cables mainly consist of a cable core, reinforcing wires (or other suitable materials), and an outer sheath. The various structures of ADSS optical cables can be summarized into two representative structures. Mainly central tube type and stranded type.

2. Technical Parameters.

Rated Tensile Strength (RTS)

Also known as tensile strength or breaking force, it refers to the calculated value of the sum of the strengths of the load-bearing cross-sections (for ADSS, it mainly calculates the aramid fibers). RTS is an important parameter for the configuration of accessories (especially tension clamps) and the calculation and control of safety factors.

Maximum Allowable Tension (MAT)

Meanwhile, based on the theoretical design meteorological conditions, the maximum tension that OPGW and ADSS can withstand is calculated. MAT is an important basis for calculating and controlling sag, tension, span, and safety factors.

Everyday Stress (EDS)

Also known as average annual operating tension, it is the average tension generated in OPGW and ADSS during long-term operation.

DC Resistance

That is, the calculated parallel resistance of all conductive elements in OPGW at 20°C should be as close as possible to the opposite ground wire. ADSS does not have this requirement.

Short-Circuit Current

For OPGW, it refers to the maximum current that OPGW can withstand during a short circuit (generally referring to a single phase). The results show that the starting and ending temperatures of the short-circuit current are related to the short-circuit current time and should be as close as possible to the actual situation. ADSS does not have this requirement.

Short-Circuit Capacity.

It is represented by the square of the short-circuit current multiplied by time, i.e., I²t. ADSS does not have this requirement.

The above is a brief introduction to common power optical cables, ADSS optical cables, and OPGW optical cables. We hope it is helpful to you.
