Burndy YS4CLBOX – Frequently Asked Questions

1) What voltage can the Burndy HYLINK copper compression splice be used on?
The Burndy HYLINK long barrel copper splice is rated from 600V minimum up to 35kV maximum, so it covers everything from building feeders through medium voltage distribution and substation work.
2) Is the Burndy HYLINK splice UL Listed and CSA approved?
Yes. The HYLINK compression splice is UL Listed to UL468A-468B and CSA Approved, which is what an inspector will look for on a medium voltage splice.
3) Can I use this Burndy splice on aluminum conductor?
No. The HYLINK long barrel splice is copper, sized for copper stranded conductors only. For aluminum or a copper-to-aluminum transition you need a bimetallic or AL-rated compression splice instead.
4) What is the difference between the Burndy YS27LBOX and the YS4CLBOX?
Both are HYLINK long barrel copper compression splices. The YS27LBOX is the single conductor size version. The YS4CLBOX covers the YS27/YS3C/YS6C/YS36 multi-size range, so order that one when the job spans more than one conductor size. Match the catalog number to the conductor you are splicing and to the die your tool takes.
5) Is the Burndy HYLINK splice a crimp connector or a mechanical set-screw type?
It is a compression splice, installed with professional compression tooling and the correct die for the conductor size. There are no set screws or bolts. If you want a reusable, tool-free connection, a mechanical set-screw splice is the other route; compression gives the permanent, low-resistance joint used on utility and substation conductor.
6) What does the long barrel design on the Burndy HYLINK splice actually do for the installation?
The extended barrel gives more conductor contact area and more mechanical strength than a standard barrel, and the chamfered entry makes pushing stranded conductor in easier. Practically, it means two crimps per side and a joint that holds up under pulling and vibration, which is why it shows up on overhead line and direct-burial work.
7) Will the tin plating on this copper splice hold up in a direct-burial or outdoor application?
The barrel is tin electroplated over copper, which resists oxidation and corrosion indoors or out. Burndy lists underground and direct-burial cable systems and overhead line splicing among the typical uses. Bury it as part of a properly taped or shrink-sealed splice assembly, not bare.
8) Do I have to buy a full case of these Burndy HYLINK splices?
No. The minimum pack quantity is 1, so you can order a single splice for a one-off repair rather than committing to a carton.
9) Is the Burndy HYLINK splice RoHS compliant?
Its RoHS compliance status is listed as CM. For projects with a hard RoHS requirement in the submittal, reference the Burndy spec sheet published for the HYLINK line.
