Overhanging hanging head is used for high-voltage transmission lines, the use of power system transmission tower poles, the entire cable is non-metallic media, self-supporting suspended on the power tower electric field strength is small position. It is suitable for the built high-voltage transmission lines, because of its comprehensive investment savings, reduce the artificial damage of the cable, high sex, no electromagnetic/strong current interference, large span, favored by the majority of power system users. It has been widely used in the communication construction of urban and rural power system transformation.
advantage
1. The construction operation is simple. It eliminates the procedure of setting up poles, setting up steel stranding wires and laying optical cables by hanging pulleys on the wires, and can fly directly across fields, ditches and rivers like power lines.
2. Communication lines and power lines are divided into systems, no matter what kind of line failure, maintenance and repair will not affect each other.
3. Compared with the bundled and wound optical cables used in the power system, ADSS is not attached to the power line or ground, and can be erected on the tower alone, and can be constructed without power failure.
4. Optical cable has the performance in high intensity electric field, is not subject to electromagnetic interference, the outer sheath made of special materials, is protected from lightning strikes.
5.The process of communication line survey and tower construction is eliminated, and the project construction is simplified.
6. The cable is small in diameter and light in weight, which reduces the influence of ice and wind on the cable, and also reduces the load of the pole and the support. Maximize the use of tower resources, high-voltage transmission cables below 500KV will be widely used.
peculiarity
1. Single-mode, multi-mode optical fiber and integrated optical cable design.
2. Smooth shape, so that the cable has aerodynamic performance.
3. The all-media optical cable structure is conducive to installation and maintenance.
4. Wide temperature adaptation range, small linear expansion coefficient, to meet the requirements of harsh environment.
5. Leak mark resistance voltage 25KV.
6. Torque balance and aramid winding, so that the cable has high tensile strength and bulletproof performance.
