PowrServ OH Triplex Al Conductor XLPE Insulation Reverse Twist Secondary (RTS) Secondary Cable

Frequently Asked Questions- Reverse Twist Secondary (RTS)Cable

I want to purchase OH Triplex Al Conductor XLPE Insulation Reverse Twist Secondary (RTS), how do I identify it?
If you want to know that the cable you are purchasing is Reverse Twist Secondary, you want to look at the number of conductors and the core material. The conductors are made of aluminum and they are two constructed in a reverse twist. A black insulation material is also used to insulate the two wires that form the phase conductors and is made of XLPE material. An aluminum alloy or ACSR conductor serving as a neutral support is used in the construction. You will see that the supporting neutral does not have an insulation. There is also a binder wire holding the conductors and the supporting neutral together.  

How is Reverse Twist Secondary (RTS) cable engineered to ensure ease of installation and performance?
The two aluminum conductors reverse twisted around the supporting neutral. Because of the alternating lay of these cables, it makes them to be less susceptible to galloping effects which is witnessed in aerial cables especially in locations where heavy winds blow. The insulation made of XLPE resists abrasion, tearing, sunlight, chemicals, and cutting. In mind span taps the alternating lay offers additional strength to the cable. 

What alternative constructions can I get for RTS cables?
If you do not want to go with the compressed aluminum wires, you can opt for copper conductors. You may also get different insulation that align with the maximum operating temperatures and the environment where you are going to do the installation. For example, you can have the high molecular-weight polyethylene insulation that is rated for temperatures of up to 75 degrees Celsius. You could also have HDPE insulation for same temperature rating (75 degrees Celsius) but where there is exposure to damage of the cable.
