The Strand Splice is a preformed wire line splice that connects or repairs damaged guy wire and messenger cable in telecommunications and power distribution. Centered over the damage point, it restores full tensile strength and ensures continuity in outside plant networks.
This splice provides holding strength equivalent to 100% of the strand’s published breaking strength, applying uniform radial pressure to minimize cable damage. Color-coded for field selection, splices are manufactured from materials matching the strand—galvanized steel, coated steel, or stainless steel—preventing galvanic corrosion and ensuring compatibility. The design improves fatigue characteristics, and installation typically requires no specialized tools, involving wrapping preformed subsets around cable ends.
Available in sizes accommodating various strand diameters, common nominal sizes include 1/4 inch, 5/16 inch, and 3/8 inch, with actual diameter ranges such as 0.231 to 0.259 inches for 1/4 inch splices. Standard lengths are approximately 35 inches. Materials often comply with American Society for Testing and Materials (ASTM) specifications, including Class B galvanized or Galfan coated steel. Splices integrate with high strength closures and are cataloged under industry-standard numbers for identification.

Frequently Asked Questions
What is the primary function of a Strand Splice?
The Strand Splice connects or repairs guy wire or messenger strand, restoring 100% of the cable's rated breaking strength. When centered over the point of damage, it provides a cost-effective solution for seamless repairs in telecommunications and power distribution systems.
What materials are Strand Splices made from?
Strand Splices are manufactured from high-strength materials such as galvanized steel, stainless steel, aluminum, or copper, matching the cable they are applied to for compatibility and to prevent galvanic corrosion.
How do you select the correct size Strand Splice?
Select a Strand Splice that matches the exact diameter of the cable being repaired to maintain the full rated breaking strength and ensure proper installation.
How do you properly install a Strand Splice?
Center the splice over the damaged area, align color marks, and wrap subsets around the cable. Apply 3-4 pitches initially, then wrap additional subsets into the previous ones. Ensure all ends snap firmly into place without using tools to prevent distortion.
Can Strand Splices be reused after installation?
Strand splices are intended for one-time use and should not be reused to ensure optimal performance and safety.
