Burndy YS25A1 – Frequently Asked Questions
1) Can a Burndy Hylink YS25A1 or YS28A1 splice be used to join aluminum wire to copper wire?
Yes. The Hylink YS-A aluminum splices are dual-rated AL/CU, so they are approved for aluminum-to-aluminum, aluminum-to-copper, and copper-to-copper stranded conductor joints. The barrel is aluminum with a tin electro-plated surface for corrosion resistance, and it comes prefilled with PENETROX A13 oxide inhibitor under an end cap, which is what makes the mixed-metal joint acceptable without adding compound in the field.
2) What conductor sizes do the Burndy Hylink YS-A compression splices cover?
Two sizes are offered: YS25A1 for 1/0 AWG and YS28A1 for 4/0 AWG (250 kcmil). Each splice is sized for one conductor size only, so both ends must be the same AWG. Pick the part by the conductor you are actually splicing, not by the cable OD.
3) How much insulation do I strip back for a Burndy YS28A1 4/0 splice, and which die do I use?
Strip length is 1-5/8 inches per conductor end on the 4/0 YS28A1, and the die index is 324 298 with a white color code. The barrel is long and internally chamfered, so the strands feed in without birdcaging. Match the die index stamped on the connector to your compression tool head before crimping.
4) Is the Burndy Hylink splice rated for medium-voltage cable up to 35kV?
Yes. The Hylink YS-A splice carries a 35 kV maximum rating (35000 V) with a 600 V minimum rating, and a 90 C (194 F) conductor temperature rating. That covers underground and overhead distribution work as well as standard 600 V commercial feeders.
5) Are Burndy Hylink YS-A splices UL Listed for inspection sign-off?
They are UL Listed and built to the UL468A-468B industry standard. If your submittal requires CSA or ETL marks, these are not carried on this splice, so specify accordingly for Canadian work.
6) Do I need to add Penetrox or joint compound before crimping the YS25A1?
No. The Hylink YS-A splices ship factory-filled with PENETROX A13 oxide inhibitor, sealed under a protective end cap. Pull the cap, insert the stripped conductor, crimp. Nothing to buy or brush on separately.
7) Will this splice work in a wet or direct-burial underground location?
The Hylink YS-A is used for underground and overhead distribution splicing. The aluminum barrel is tin electro-plated for corrosion resistance and the prefilled oxide inhibitor guards the strands at the joint. It is a compression connector, not an insulated or moisture-sealed splice, so in a direct-burial application it still needs the appropriate tape, sleeve, or mold insulation system over it.
8) Can I use an aluminum Hylink splice on a copper-only run, or should I use a copper splice?
An all-copper splice is fine here. The Hylink YS-A is dual-rated AL/CU, and copper-to-copper is one of the approved combinations, so you can standardize on one part number across mixed and copper-only joints rather than stocking two families. Just keep the die index and conductor size correct.
9) What are the barrel dimensions on the Burndy YS28A1 4/0 splice?
Overall length is listed as 3.18 in / 3.06 in with an outside diameter of 0.92 in / 0.85 in. That OD matters when you are splicing inside a raceway, pedestal, or handhole with limited clearance, and when sizing the insulating sleeve that goes over the finished crimp.
