Helical Rod Spacer

The HELICAL ROD Spacer is recommended for use on horizontal, twin conductor bundles.

The functions of the HELICAL ROD Spacer are:

To provide uniform spacing of horizontally bundled subconductors
To insure consistent electrical characteristics
To minimize wind induced motions such as subconductor oscillation and aeolian vibration so that no conductor damage results
To keep the subconductors from entangling due to galloping, ice unloading, and fault currents.

Thermal Rating (Continuous) 125°C
Constructed entirely of high strength aluminum alloy wire formed into helical rods
No loose parts or troublesome articulated joints to create radio noise through looseness
Designed to be coronafree at voltages 10-20% above operating up to 500 kV AC and 750 kV DC
Applied easily and uniformly without tools and can be installed with hot line tools
Designed to meet fault current requirements developed in most EHV line design.
Complete fault current testing and analysis has been completed for the HELICAL ROD Spacer and is published in AIEE paper DP 58-779, and IEEE paper 63-88.
