Built from high-conductivity wrought aluminum with an electro-tin plated finish, this 600V to 35kV rated splice is UL Listed to UL468A-468B and engineered for utility, industrial, and commercial electrical professionals who need proven, code-compliant connections.

Key Features

  • Conductor Range: Accommodates aluminum and copper stranded conductors from 300 kcmil up to 750 kcmil for precise, optimized crimp performance.
  • Durable Construction: High-conductivity wrought aluminum with heavy-duty wall thickness provides superior conductivity, low resistance, and reliable crimp forming.
  • Compression Splice Design: Internally bevelled barrel eases cable insertion, while a solid center stop prefilled with PENETROX oxide-inhibiting compound ensures proper insertion depth and forces compound between wire strands.
  • Voltage Rating: 600V minimum to 35kV maximum, suitable for distribution, transmission, and substation applications.
  • Finish: Electro-tin plated finish provides durable corrosion resistance for long-lasting performance in demanding environments.
  • Installation System: Color-coded end caps aid wire-size identification and keep the connector interior free of contamination prior to installation; compatible with hydraulic and mechanical compression tools including HYTOOL and HYPRESS systems.

Burndy YS4CA1 – Frequently Asked Questions

1) What wire sizes does the Burndy HYLINK YS aluminum compression splice cover?
The HYLINK YS aluminum splice is ordered by conductor size, and the range runs from 8 AWG up through 700 kcmil. The individual catalog numbers are YS8CA1 (8 AWG), YS4CA1 (4 AWG), YS2CA1 (2 AWG), YS26A1 (2/0), YS27A1 (3/0), YS30A1 (300 kcmil), YS31A1 (350 kcmil), YS34A1 (500 kcmil), YS36A1 (600 kcmil) and YS39A1 (700 kcmil). One splice covers one conductor size, so order by the size of the cable you are joining, not by the circuit.
2) Can I use a Burndy aluminum HYLINK splice to join copper to aluminum cable?
Yes. The HYLINK YS aluminum splice is rated for aluminum-to-aluminum, aluminum-to-copper, and copper-to-copper conductor combinations, which is why it is the one to reach for on a transition splice where an existing copper feeder meets new aluminum. The barrel is high-conductivity wrought aluminum with an electro-tin plated finish, and it comes prefilled with PENETROX oxide-inhibiting compound, which is what makes the dissimilar-metal connection hold up. Both conductors must be stranded and both must be the size the catalog number is built for.
3) What voltage is the Burndy HYLINK YS compression splice rated for?
600V minimum up to 35kV maximum, so the same splice family works on building feeders and on medium-voltage distribution, transmission and substation cable. That upper rating is why it shows up on underground and overhead utility work rather than just inside a panel. The splice itself is a bare connector, so the insulation or re-jacketing over it has to be rated for the system voltage you are running.
4) Do I need to apply oxide inhibitor before crimping a Burndy HYLINK YS splice?
No, the HYLINK YS splice ships prefilled with PENETROX oxide-inhibiting compound, so there is no separate tube to buy or apply. The barrel has a solid center stop that both sets the insertion depth and forces the compound out between the wire strands as the conductor goes in, and the internally bevelled entry helps the strands feed without birdcaging. Color-coded end caps keep the compound and the barrel interior clean until you pull them at installation, so leave them on until you are ready to make the splice.
5) What tool do I need to crimp a Burndy aluminum HYLINK compression splice?
A compression tool, hydraulic or mechanical, from the Burndy HYTOOL and HYPRESS systems. This is a crimp connector, not a mechanical set-screw splice, so there is no version of it you can install with hand wrenches alone. If you do not already own or rent the compression head that covers your conductor size, a set-screw or bolted splice is the alternative approach; the tradeoff is that a compression splice gives you a lower-profile, permanent joint that pulls through conduit and takes re-jacketing better.
6) Is the Burndy HYLINK YS a long barrel or short barrel splice?
Long barrel, standard barrel style, catalogued by Burndy as the YS-A configuration. The long barrel gives more crimp length per conductor, which is what a heavy-wall aluminum splice needs to hold pullout strength on large stranded cable. Practically it means you need more straight, accessible cable length at the joint than a short-barrel connector would take, so plan the window in the vault or trough accordingly.
7) Is the Burndy aluminum HYLINK splice a two-conductor inline splice or a tap connector?
It is an inline splice: two conductors enter opposite ends of a single barrel and butt against the internal center stop, joining one run of cable end to end. It is not a tap, a tee, or a terminal lug, so if you need to branch a conductor off a run or land a cable on a bus or breaker pad, this is the wrong part and you want a tap connector or a compression lug instead.
8) Why is the Burndy HYLINK splice tin-plated instead of bare aluminum?
The electro-tin plating is corrosion protection. On direct-buried, underground vault, and overhead distribution work the connection sees moisture and dissimilar-metal contact, and bare aluminum oxidizes at the interface. Tin plating over the high-conductivity wrought aluminum barrel keeps the contact surface stable, and it is also what makes the copper-to-aluminum transition practical. Combined with the prefilled PENETROX inside the barrel, the joint is protected on both the outside and between the strands.
