Reducing splices permanently join two conductors of different diameters through compression without requiring tools for hand application. Built from high conductivity seamless copper tubing with tin plating to inhibit corrosion, these connectors ensure optimal conductivity and environmental resistance. Dual-rated models accommodate both aluminum and copper conductors and may be factory pre-filled with oxide inhibitor such as PENETROX™ to prevent galvanic corrosion.
Design features include inspection windows in each barrel to verify full cable insertion and chamfered barrel entries for smooth wire insertion without strand damage. Color-coded end caps and barrels display conductor gauge sizes and die index numbers for proper identification, while crimp location bands enable precise tool application. The splices facilitate spinner-free travel without gate adjustments or lifting requirements, maintaining compatibility with strand material.
Certifications include cULus Listing per UL486A-B for power applications and UL467 for grounding, bonding, and direct burial. Models may meet UL224 VW1 flame resistance standards and pass abrasion and cut tests per TELCORDIA GR-347-CORE. Tooling compatibility extends to Penn-Union, Burndy, Thomas & Betts (T&B), Huskie, Greenlee, and Versa-Crimp compression tools as confirmed by cULus listings, ensuring reliable crimping in field applications.

Frequently Asked Questions (FAQS)
What is the intended use of the reducing splice?
The reducing splice is intended to permanently join two strands of different diameters.
What are the advantages of using this reducing splice?
Advantages include easy hand application with no tools required, spinner-free travel design that permits passage without adjusting gates or lifting the spinner, material compatibility with both aluminum and copper conductors, hot-dip galvanized corrosion protection, and cULus Listed certification for power applications, grounding, bonding, and direct burial per UL 486A-486B standards.
How is the reducing splice installed?
It is quickly and easily applied by hand with no tools or specialized equipment required, making it efficient for field crews.
Can the same reducing splice be used for different conductor types?
Yes, the reducing splices are dual rated for both aluminum and copper wire, featuring an internal chamfer for smooth wire insertion and are prefilled with oxide inhibitor to ensure proper connections.
How do the reducing splices perform in harsh or corrosive environments?
The splices are made of material completely compatible with the strand and are hot-dip galvanized to inhibit corrosion, allowing them to be used in any environment with long-term durability.
