Armour Rod is a pole line hardware accessory that protects cables in electrical transmission and distribution lines from mechanical stresses including bending, compression, abrasion, and flash-over. It repairs damaged aluminum-based conductors by restoring their mechanical strength and electrical conductivity, extending cable lifespan and reducing maintenance costs while ensuring reliable power transmission.
Armour Rods are constructed from aluminum wire, galvanized steel wire, or aluminum clad steel wire, with material selection aligned to the conductor’s composition to prevent corrosion. They are classified by function into preformed rods for cable protection, repair rods for conductor damage restoration, and connection repair rods for specific applications. Features include color coding for easy identification of conductor sizes, anti-corrosion treatments, and lightweight elastic design supporting hand installation. They provide high strength rated at not less than 95% of the conductor’s strength and offer vibration protection, with thermal ratings capable of withstanding temperatures up to 250°C in suspension clamps.
Installation is straightforward and performed by hand without powering down the system. The process involves marking the conductor surface, aligning the Armour Rod’s color code with the mark, rotating it approximately 1 to 1.5 grip distances, and wrapping it securely along the cable according to the helical direction. The design allows customization in length and material, supporting various conductor types including Aluminum Conductor Steel Reinforced (ACSR), All Aluminum Alloy Conductor (AAAC), and Optical Ground Wire (OPGW).

Frequently Asked Questions
What is an armour rod and why should I use one?
Armour rods are accessories that protect cables in transmission and distribution lines from mechanical stresses like bending, abrasion, and flash-over. Using them enhances the longevity of your lines by preventing damage, which reduces maintenance costs and ensures reliable power transmission.
What types of armour rods are available?
Armour rods are classified by function. Preformed rods protect cables from stress and abrasion. Repair rods restore damaged aluminum-based conductors—if damage is less than 7% of the cross-sectional area, they restore 100% of the conductor's original mechanical strength and conductivity. Connection rods are used for specific connection applications.
Are armour rods easy to install?
Yes, they are designed for simple installation by hand. The pre-formed rods wrap securely by aligning color codes with a mark on the conductor. No special tools, extensive experience, or power disruption are required, saving time and labor costs.
What specifications and customization options are available?
Select a material matching your conductor (aluminum wire, galvanized steel wire, or aluminum clad steel wire) to prevent corrosion. Key specifications include thermal rating (up to 250°C), diameter range, and length. We support all standard sizes and offer full customization of materials, sizes, and color-coding. Our rods are manufactured with anti-corrosion treatments, have a rated strength of not less than 95% of the conductor's strength, and meet industry standards for extra-high voltage applications.
