The fixing fixture ‌ is a fixture used for fixing wires or pipelines, mainly used for fixing ADSS and OPGW optical cable on the pole and tower. Its role is to fasten the cable on the tower to prevent the cable from being damaged by friction with the tower or other objects under the action of wind, so as to protect the safety of the cable.

he use and function of the drawdown fixture

Fixed installation: The lead down fixture is mainly used for the fixed installation of ADSS and OPGW cable on the pole. For example, at the cable connector bar (tower), the cable is led from the clamping device to the installation of the protection box. The cable is led down from the pole tower to the underground pipeline, cable trench, direct burial, and led down into the machine room and other places to fix
Prevent wear: By fastening the optical cable on the pole and tower, avoid the optical cable from being damaged by friction with the pole and tower or other objects under the action of wind, and protect the safety of the optical cable
The clamping clamp is mainly used for the fixed installation of optical cable on the tower to avoid optical cable wear and ensure its safety.
The lead down clamp is a kind of clamp which is suitable for the insulating lead down of optical fiber wire compound overhead ground wire. It can fix the optical cable firmly on the pole or tower to prevent the optical cable from shaking and wearing. This fixture is usually installed in the first, end rod, continuation rod and other places of the cable line, generally every 1.5 meters to 2 meters or so to install a ‌12.
The common materials of fixed fixtures (lead down clips, wire clips) include cast iron, aluminum alloy, steel and hot-galvanized iron parts, mainly used for connecting and fixing power lines or optical cables.

Material

Cast iron: simple structure, stable quality and corrosion resistance, but high density, heavy weight, installation should pay attention to strength and weight ‌1.

Aluminum alloy: Light weight, high strength, excellent electrical conductivity and corrosion resistance, easy to install, can maintain shape and performance under climate change ‌12.

Steel: high strength, hardness, corrosion resistance, more durable than other materials, often used to connect large equipment ‌1.

Hot-galvanized iron parts: with good corrosion resistance and strength, often used in outdoor environment ‌45.

‌Uses ‌

The fixed fixture (down drawing clamp, wire clamp) is mainly used to connect and fix the lower vertical line, crossing line, and insulated wire on the power line, etc., to ensure the safe operation of the line and power transmission ‌1.

In the field of optical cables, such as OPGW/ADSS optical cable fixing clamp, used to fix optical cables with poles or towers, to ensure the stability and safety of optical cables ‌24.

These fixtures and wire clamps play a vital role in power systems and communication networks, ensuring the stable transmission of power and signals.

According to the different application scenarios, the lead clamp can be divided into rod lead clamp and tower lead clamp. The rod lead clamp is usually connected to the pole by a 304 stainless steel band holder, while the tower lead clamp is connected to the tower Angle steel by a hot-dip galvanized U-shape ‌4. To complete the installation ‌3, fix the lead down clip on the tower, and then insert the optical cable into the parallel groove of the clamping plate. Adjust the optical cable and tighten the inner and outer nuts of the clamping plate.

In addition, the specifications and models of the downlead clamp are various, which can meet the needs of different projects. For example, there are special lead down clips for OPGW optical cables, there are also lead down clips for ADSS optical cables, etc ‌5. When selecting the downlead clamp, it is necessary to select the appropriate clamp according to the type and specifications of the cable and the specific use scenario.

In general, the fixed fixture down clip plays a vital role in the cable line, they can effectively protect the cable from wear and damage, to ensure the safe and stable.
