As we all know, in the communications industry, power industry and construction industry, we usually use drop wire clamps to fix or hang cables.
Why are drop wire clamps so important? And how do we use them? If you don’t know this yet, don’t worry. In this article, we will take a deep look at drop wire clamps so that you can better choose and use them.
What is the drop wire clamp？
The drop wire clamp (also called FTTH drop wire clamp, drop clamp for fiber cable, drop cable clamp, and fiber optic drop wire clamp) is a hardware used to fix and hang the guy wire (such as wire rope, etc.) on the towers and utility poles.
It is mainly responsible for fixing the guy wire, bearing the tension and protecting the guy wire.
Why are they called drop wire clamps?
As the name implies, they are direct descriptions of function and structure. The guy wire refers to a steel strand or wire rope used in the power, communication, and construction industries to withstand tension (such as the inclined guy wire on utility poles or the cable clamp on towers). The clamp refers to hardware that generates friction by wedging or clamping to lock an object. The engineering field likes to use this unambiguous naming.
What is the purpose of drop wire clamps?
For electrical power systems
Power transmission is essential to our daily lives. The cities and villages have long transmission lines, and many electric poles or electric towers are needed to support them. Since electrical poles and towers bear huge tensile forces, on the other side of the electric poles, it is necessary to use drop wire clamps to connect the cables, the electric poles and the ground to apply lateral tension to maintain balance.
For communication systems
Used to support signal towers or signal base stations, it has much the same function as the drop wire clamps in electrical power systems.
Accessories for use with drop wire clamps
Designs of drop tension clamps can be used with a variety of pole line hardware together. They share the tension of the utility poles and prevent them from tilting or collapsing.
1.Stainless steel band
The stainless steel band is used to fix the hook on the rod and connect the drop wire clamp to fix it.
2.Drop attachment bracket
The plum ping hook is a type of drop arrangement bracket, which is used to connect the head of the cable clamp and plays a connecting role.
3.Electrical cross arm
A piece of hardware that is mounted on a utility pole and has holes in it for drop wire clamps.
4.Shackle
Shackles are U-shaped removable connectors that are locked at both ends with a stainless steel cross pin and are used to quickly connect cable clamps or wire ropes.
5.Guy wire
Guy wires are high-strength steel strands that are used with guy wire clamps to keep the pole stable.
When do you need to use drop wire clamps?
Almost all utility poles or towers over 20 feet tall require drop wire clamps. The higher the pole is, the more it will shake under the influence of wind. Using drop wire clamps to apply force in the lateral direction of the poles can effectively keep poles stable. Installing and using drop wire clamps in steep hillsides, plains with sweeping winds, or tropical areas with severe weather and frequent rain is very effective.
How to use the drop cable clamps?
They are used to support various poles and towers in power systems, or to support antenna masts for broadcasting and communications. Put the guy wire into the groove of the drop wire clamp, then put in the gasket and wedge, tighten the drop wire clamp, and finally fix the head pull ring of the clamp on the electrical cross arm of the utility pole or the bracket of the tower.
The following video will show you how to use drop cable clamps.
Although the dorp wire clamp is easy to install, it also requires experienced installers to install it. Wear appropriate protective equipment before installation and prepare the tools needed.
Inspection and testing of drop wire clamps
Tensile testing can ensure the safety of clamps during use. Tensile test of the wire clamp, use appropriate equipment to test the load energy of the cable clamp to ensure that the tensile strength of each cable clamp meets the standard.
Features of high-quality drop wire clamps
- The texture is uniform, with metallic luster.
- Strong and durable, long service life.
- High tensile strength, can withstand huge tensile force.
- Simple installation and high installation efficiency.
- Aluminum alloy or stainless steel drop wire clamp, good corrosion resistance.
- Nylon gasket to prevent cable damage.
