Advantages of Strand Splice

High Conductivity: Utilizes premium conductive alloys to ensure low-resistance connections, minimizing power loss.

Longitudinal Holding Strength: A strand splice is designed to have a longitudinal holding strength equivalent to the ultimate tensile strength of the messenger strand it is used on. This means the connection is just as strong as the original strand, ensuring reliability.

Corrosion Resistant & Durable: Surface treated with anti-corrosion coatings, it withstands harsh environments including high temperatures, humidity, and salt spray, with a lifespan exceeding 30 years.

Easy Installation: Requires no specialized tools or heat sources; simple manual wrapping completes the installation, saving time and labor costs.

Strong Compatibility: Adaptable to various conductor types (e.g., ACSR, copper cables) and supports connections between different conductor diameters.

Application of Strand Splice

01/

Power Transmission: Splicing and repair of conductors in high-voltage transmission lines, distribution networks, and substations.

02/

Renewable Energy Sector: Cable connections in wind turbine generators and combiner box systems in photovoltaic power plants.

03/

Rail Transportation: Splicing of contact wires for high-speed rail and metro systems, ensuring power supply stability.

04/

Communication Engineering: Lightning protection splicing for Optical Ground Wire (OPGW) and communication cables.

05/

Emergency Repair: Rapid restoration of power lines after natural disasters, minimizing outage duration.

06/

Industrial & Construction: Applications such as factory power distribution and cable connections for bridge stay cables.

Material of Strand Splice

Galvanized Steel

A common choice, offering good strength and corrosion resistance due to the zinc coating.

Stainless Steel

Offers superior corrosion resistance, especially in harsh environments. Different grades (like Type 302 or 316) offer varying levels of resistance and strength.

Aluminum

Used in some applications where weight is a concern or where the environment doesn't require the strength of steel.

Specialty Materials

In some cases, specialized materials like Mischmetal Alloy (AL/ZN) or Copperweld may be used, depending on the specific application and strand type.

How to install Strand splice?

General Notes

1.01 Prefrmed Splices are precision products.To insure a tight assembly they should be stored and handled carefully to prevent distortion and damage, and should be installed as illustrated.
1.02 To reduce the possibility of distortion, do not use tools to snap the ends in place. The ends should be snapped in place as shown in 5.00.
1.03 At no time should the rod end be staggered in excess of 1/2 pitch length.
1.04 Strand splices were not designed nor tested for use on overhead shield wires and are not intended for that application
1.05 Strand Splices should not be reused after original application. Lay direction of both the splice and the strand should be the same. Most strand is left-hand lay.

2.00Tape the ends of strand with a thin layer of tape. Use the subset of the Preformed Splice which contains the greater number of rods and begin the application as shown.

3.00 Position second cut strand end against the first and completely apply remainder of subset. Do not exceed 1/4" (6 mm) separation of the strand ends.

4.00 Align center marks and apply second subset one or two wraps each side of center mark, then apply third subset in same manner. Now wrap on second and third subsets simultaneously.

5.00 For easier application, split the legs of each subset as shown.

FAQ

Q: Can u provide us with samples?

A: Yes, we can provide 1-2 pieces free samples, But u should pay express cost or u provide us with express account number.

Q: If we need customized/OEM product,Can u supply?

A: Yes,Customized/OEM product/artwork is available for us.Professional designers,Advanced technicians and mold modifications department ensure that we will make the exact model for u accordingly.

Q: What payment terms available for u?

A: If order amount less than 10000USD,100% T/T;If amount more than 10000USD,30%T/T in advance plus 70%T/T before shipment.

Q: What is ur delivery time?

A: Normally, it will be shipped within two weeks after prepayment; if the order is large, it will take one month, depending on the order quantity.

Q: How does a Strand Splice restore cable strength?

A: A Strand Splice restores 100% of the strand’s published breaking strength when properly installed over damaged areas. The preformed rods wrap around both cable ends, distributing tension evenly across the splice area, providing maximum strength and excellent fatigue characteristics for both strand and messenger cables.

Q: What materials are Strand Splices made from?

A: Strand Splices are manufactured from high-strength materials matching the cable they’re connecting, including galvanized steel, aluminum, or stainless steel. This material compatibility ensures optimal performance and prevents galvanic corrosion between different metals.

Q: How do you install a Strand Splice?

A: Installation involves centering the splice over the damaged area, aligning color marks, and wrapping subsets around the cable. Apply 3-4 pitches initially, then wrap additional subsets into the previous ones. Split wire ends if necessary for easier installation and ensure all ends snap firmly into place.

Q: What types of cables can Strand Splices be used with?

A: Strand Splices are compatible with guy wires, messenger cables, and overhead line hardware in telecommunications and power distribution systems. They come in various sizes to match different cable diameters for aerial, underground, and pedestal installations.

Q: How do you determine the correct Strand Splice size?

A: Select a Strand Splice that matches the exact diameter of the cable being repaired. The splice must be the same size as the strand or messenger wire to ensure proper installation and maintain the full rated breaking strength of the cable.

Q: Can preformed splice connectors be reused?

A: Strand splices are intended for one time use and should not be re-used after the original application to the strand.
