The Difference Between ADSS Optical Cable PE Sheath and AT Sheath

All-dielectric self-supporting (ADSS) Optical Fiber Cables provide fast and economical transmission channels for power communication systems due to their unique structure, good insulation, high temperature resistance, and high tensile strength.

Generally speaking, ADSS optical cables are cheaper than optical fiber composite ground wire OPGW cables in many applications, and are easier to install. It is advisable to use power lines or towers near them to erect ADSS optical cables, and even in some places it is necessary to use ADSS optical cables.

The difference between AT sheath and PE Sheath in ADSS optical cable:

AT and PE in ADSS optical cable refer to the sheath of the optical cable.
PE sheath: ordinary polyethylene sheath. For use on 10kV and 35kV power lines.
AT sheath: Anti-tracking sheath. For use on 110kV and 220kV power lines.

Advantages of ADSS Optical Cable laying:

1. Strong ability to withstand extremely severe weather (strong wind, hail, etc.).
2. Strong temperature adaptability and small linear expansion coefficient, meeting the needs of harsh environmental conditions.
3. The small diameter and light weight of optical cables reduce the impact of ice and strong winds on optical cables. It also reduces the load on power towers and maximizes the use of tower resources.
4. ADSS optical cables do not need to be attached to power lines or bottom lines. They can be erected independently on towers and can be constructed without power outages.
5. The performance of optical cables under high-intensity electric fields is extremely superior and will not be affected by electromagnetic interference.
6. Independent from the power line, easy to maintain.
7. It is a self-supporting optical cable and does not require auxiliary hanging wires such as hanging wires during installation.

The main uses of ADSS optical cables:

1. Used as the lead-in and lead-out optical cable of the OPGW system relay station. Based on its safety attributes, it can well solve the power isolation problem when leading in and out of the relay station.
2. As a transmission cable for optical fiber communication systems in high-voltage (110kV-220kV) power networks. In particular, many places conveniently make use of it when renovating old communication lines.
3. Used in optical fiber communication systems in 6kV~35kV~180kV distribution networks.
