Armour Rod

The PREFORMEDTM Armour Rods are intended to protect conductors/strands against bending, compression, abrasion and arcover damage and to provide restorative repair.

The degree of protection needed on a specific line depends upon a number of factors, such as line design, temperature, tension, exposure to wind flow and vibration history on similar construction in the same area.

As a general guide the following recommendations may be adapted to the specific conditions:

• Armour Rods are recommended as minimum protection for clamp-type supports and suspensions.
• Armour Rods are recommended as minimum protection for hand tied spans of 90m or more.

PREFORMEDTM Armour Rods may be used to restore full conductivity and mechanical strength to conductors/strands where damage does not exceed approximately 50% of the outer layer and when located at point of support or within the mid span area and is located within the centre third section of the repair fitting.
