Span Clamp
There is a high chance that you use a mid-span on your transmission line. The best way to connect this span into position is by using a span clamp. The accessory provides a perfect attachment point for the mid-span. This function is common when you are dealing with aerial connections of the transmission lines.
The clamping action of the span clamp limits the unwarranted movement of the mid-span. It prevents the vibration of the cable hence guaranteeing the uninterrupted flow of the electric current and communication signals for the telecommunication lines.
The robust construction of the span clamp is a key factor that contributes to its effectiveness. It is physically strong to withstand mechanical forces that may act against it. The strength also makes it capable of supporting the weight of the mid-span.
The steel metal of the span clamp is also resistant to the effects of rust and corrosion. It is also galvanized to the ASTM standards. You can be sure of the durability and reliability of this clamp.
A span clamp comes with grade 2 steel bolts that are used for completing the connections and affecting the operations of the clamp.
Features
- Has high tensile strength
- Can accommodate different sizes of messenger strands
- Resistant to rust and corrosion
- The front-end of the clamp is threaded for easy installation
Frequently Asked Questions
What is a span clamp?
A span clamp is a transmission line fitting that is used for supporting the mid-span which is in turn connected to an aerial cable. The clamp ensures that the mid-span remains stable at all times despite the external forces exerted against it.
What is the span clamp made of?
The span clamp is made of high-grade steel metal that is hot-dip galvanized. The strength of the steel alone is enough to provide the necessary support. The 75,000 PSI tensile strength says it all. The metal is further galvanized to have protection against rust and other chemical damage.
When do I need a spam clamp
Let’s say you have cables in your transmission line and you want them to pass through a certain area that is full of obstacles such as trees and buildings. In such cases, you will need a mid-span that will pull conductors away from the obstacles. This mid-span will then be connected to the span clamp.
How to install a span clamp?
Start by positioning the clamping plates on a messenger strand then tighten the nut. Proceed to insight the wire hook of the mid-span into the clamp hook.
