Audited Supplier The suspension clamp is an accessory product that is often used in the field of power optical cables to play a protective role, but it is used differently in different situations.
ADSS/OPGW optical cable is used for high-voltage transmission lines, using power system transmission towers, 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.
ADSS/OPGW pre-twisted wire suspension clamps are mainly used on overhead self-supporting ADSS/OPGW optical cable lines for suspending optical cables, similar to ordinary suspension clamps.
Features:
1. The reasonable distribution of extremely low static stress improves the bearing capacity of dynamic stress (such as vibration or galloping), and its grip strength can reach 10% to 20% of the ultimate tensile strength (RTS) of the optical cable.
2. There is no rigid contact with the optical cable (flexible grip), which minimizes wear and tear.
3. The high-quality material makes the clamp have good elasticity and toughness, strong fatigue resistance and corrosion resistance, and a long safe service life.
4. It not only effectively protects the optical cable, but also its smooth outline greatly reduces corona discharge and electromagnetic loss. The pre-twisted wire suspension clamp is composed of inner skeined wire, outer skeined wire, rubber insert, suspension splint (housing) and so on.
Advantages:
1. Simple construction work. 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 are 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, and is free from electromagnetic interference, and the outer sheath made of special materials is protected from lightning strikes.
5. The process of communication line survey and tower construction is omitted, which simplifies engineering construction.
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.
