Power cable manufacturers: ADSS cable and OPGW cable is different
Release Date: 2022-11-15

In the communication industry, ADSS optical cable and OPGW optical cable have been fully used. It is also since the advent of optical fiber, it immediately got great interest from the power sector, and now many of them have become new telecom operators, all because they have tower resources. There are ADSS cable or OPGW cable above, both need to be able to use for a long time, the required material quality is good, must find a regular manufacturer production.

Power cable manufacturers: ADSS cable and OPGW cable is different

ADSS cable and OPGW cable is different

1. Different structures.

The OPGW cable consists mainly of a cable core (optical fiber unit) containing optical fibers and a metal strand (including aluminum clad steel wire). Galvanized steel wire. Aluminum alloy wire. Duralumin wire). So far, there have been hundreds of different structures, which can be summarized into three main types.

Aluminium tube type. Aluminium frame. Pipe type. Steel tube type.

ADSS cable is mainly composed of cable core, reinforcing wire (or other appropriate materials) and outer sheath. The various structures of ADSS optical fiber and cable can be summarized into two representative structures. Mainly center tube type, layer stranded type.

2. Technical specifications.

Rated tensile strength (RTS)

Also known as tensile strength or breaking force, it refers to the calculated value of the sum of the strength of the bearing section (ADSS mainly calculates aramidon). RTS is an important parameter for the calculation and control of the configuration and safety factor of the tool, especially the tensioning clip.

Maximum tensile strength (MAT)

Also, according to the designed meteorological condition theory, the maximum tension of OPGW and ADSS was calculated. MAT is an important basis for the calculation and control of sag, tension, span and safety factor.

Average daily operating tension (EDS)

Also known as the annual average working tension, it is the average tension generated by OPGW and ADSS in the long-term working process.

Direct current resistance

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

Short circuit current

OPGW refers to the maximum current that an OPGW can withstand when it is short-circuited (generally referred to as a single-phase pair). The results show that the start and end temperature of short circuit current is related to the time of short circuit current and should be as close as possible to the actual situation. ADSS does not have this requirement.

Short flow capacity.

Short circuit current squared and time times I2t. ADSS does not have this requirement.

The above is about the common power cable, adss cable and opgw cable brief introduction, I hope to help you.
