ADSS optical cable is used for high-voltage transmission lines, using power system transmission tower poles, the entire optical cable is a non-metallic medium, and is self-supporting and suspended at the position where the electric field intensity is the smallest on the power tower. It is suitable for the built high-voltage transmission lines, because it saves comprehensive investment, reduces the man-made damage of optical cables, has high safety, no electromagnetic/strong electric interference, and large span, and is favored by the majority of power system users. It is widely used in the communication construction of power system urban network transformation and rural network transformation.
Advantages of ADSS optical cable:
1. The construction work is simple. It eliminates the procedures of erecting poles, erecting steel strand suspension wires and hanging pulleys on the suspension wires to lay optical cables. It can fly directly across fields, ditches and rivers like power lines.
2. Communication lines and power lines form separate systems. No matter which line fails, maintenance and repair will not affect each other.
3. Compared with the bundled and wound optical cables used in power systems, ADSS is not attached to power lines or ground wires, and is erected on poles and towers alone, and can be constructed without power failure.
4. The optical cable has superior performance in high-intensity electric fields, is free from electromagnetic interference, and the outer sheath made of special materials is protected from lightning strikes.
5. The survey of communication lines and the construction of pole towers are omitted, which simplifies the construction of the project.
6. The diameter of the optical cable is small and the weight is light, which reduces the impact of ice and wind on the optical cable, and also reduces the load on the tower and support. To maximize the use of tower resources, it will be widely used in high-voltage transmission cables below 500KV.
Features of ADSS optical cable:
1. Single-mode, multi-mode optical fiber and integrated optical cable design.
2. The smooth shape makes the cable have superior aerodynamic performance.
3. The all-dielectric cable structure facilitates installation and maintenance.
4. The temperature range is wide, and the linear expansion coefficient is small, which meets the requirements of harsh environments.
5. The leakage resistance voltage is 25KV.
6. The torque balance and aramid fiber winding make the optical cable have extremely high tensile strength and bulletproof performance.
