ArabicWhat is the drop wire clamp?
Drop wire clamp (also known as service clamp, service drop clamp,fiber drop clamp,drop cable clamp.)
It is used to temporarily or permanently fix the drop wire to the overhead main line, while sharing tension and ensuring power transmission.
Structure of drop wire clamp
If you want to quickly install or remove the clamp, understanding its composition is necessary.
Shell – It is a metal shell made of 201/304 stainless steel or aluminum alloy.
Wedge – Stainless steel wedges for clamping cables.
Stainless steel or plastic gasket – The function of the gasket is to prevent the cable insulation layer from wearing out.
U-shaped pull ring – Used to hang the drop wire clamp on the electrical cross arm of the utility pole.
Now that you know the components of the universal fiber drop clamps, I will show you how to install them.
How to install drop wire clamps? – Fasten your seatbelts!
To install the drop wire clamp, first remove the wedge from the housing. Then, place the electrical or fiber optic cable you wish to hang into the housing’s groove. Place a washer over the cable insulation, then clamp the wedge around the cable, tightening it to increase friction and secure it. Finally, use the U-shaped pull ring to attach it to your utility pole or house support. It’s that simple. However, be aware that if the fiber cable clamp isn’t securely engaged, the entire service line will sway in the wind, potentially bending the main cable.
A few things you need to pay attention to
1.Take proper insulation measures and de-energize the line. You’ll need to use essential tools like insulating gloves and a blanket. Only after everything is ready can you touch the wires.
2.If you need to strip the insulation of the main line, use a professional wire stripping tool.
When placing the cable into the housing’s groove, make sure the groove perfectly matches the wire diameter. Then, insert the washer and wedge into the groove to prevent the cable from slipping out. Remember, you don’t need to use too much force, as the actual force holding the cable in place is the tension on the cable clamp.
3.After the completion inspection, you need to check whether the installed drop wire clmap hardware and wiring are complete and whether there are any signs of looseness. Whether the connection between the U-shaped ring and the power crossarm or bracket is loose or corroded. If so, please replace it in time.
How do I remove a drop wire clamp?
I’ll show you how to remove the cable when your project is complete or you no longer need it hanging.
1.Before dismantling, you must ensure that the line is de-energized or that insulation facilities are in place.
2.Use tensioning pliers to release the tension on the wire and allow the cable to rebound.
3.Remove the drop cable clmap housing and take the cable out of the housing’s groove.
4.Remove the U-ring and wedge and place them in the tool bag.
5.Remove the tensioners and ground wires, and check all tools to ensure there is no leftover hardware on the pole or bracket.
Frequently Asked Questions
What is the drop wire clamp？
Drop wire clamp (also known as drop cable clamp, drop tension clamp, service drop clamp, fiber drop clamp.)
How to pull out the wedge if it is stuck too tightly?
If the cable is too tightly wedged in the wedge, and the tensioner still won’t pull it out even after it’s loosened, you can gently tap the end of the wedge twice with a copper hammer (remember, use a copper hammer; a steel hammer will leave sparks). The tapping should follow the direction of the conductor. The wedge will automatically rebound after the shock, allowing the cable to be removed smoothly.
