All dielectric self-support optic cable
The All dielectric self support optical cable has unique structure, good insulation and high temperature resistance, as well as high tensile strength, providing a fast and economical transmission channel for power communication systems.
Generally speaking, ADSS fiber optic cable is cheaper than OPGW fiber optic composite ground wire cable in many applications, and it is easier to install. It is advisable to use power lines or nearby towers to install ADSS optical cables, and in some places, the use of ADSS optical cables is even necessary.
The AT and PE in ADSS optical cables refer to the sheath of the optical cable.
PE sheath: ordinary polyethylene sheath. Used for 10kV and 35kV power lines.
AT sheath: anti electric trace sheath. Used for 110kV and 220kV power lines.
Advantages of ADSS fiber optic cable laying
1. Strong ability to withstand extreme weather conditions such as strong winds and hail.
2. Strong temperature adaptability, low coefficient of linear expansion, meeting the needs of harsh environmental conditions.
3. The optical cable has a small diameter and light weight, which reduces the impact of ice and strong winds on the optical cable, and also reduces the load on power towers, maximizing the utilization of tower resources.
4. ADSS optical cables do not need to be attached to power lines or bottom lines, and can be separately installed on towers for construction without power outages.
5. Optical cables have extremely superior performance under high-intensity electric fields and are not affected by electromagnetic interference.
6. It is independent of the power line and easy to maintain.
7. It belongs to self-supporting optical cable and does not require auxiliary hanging wires such as hanging wires during installation.
The main uses of ADSS optical cable are:
(1) By using it as an introduction and extraction optical cable for OPGW system relay stations, based on its safety attributes, the problem of power isolation can be effectively solved when introducing and extracting relay stations.
(2) Utilize it as a transmission optical cable for fiber optic communication systems in high-voltage (110kV-220kV) power grids. Especially in many places, it is very convenient to utilize it when renovating old communication lines.
(3) Apply it to fiber optic communication systems in 6kV~35kV~180kV distribution networks.
