Burndy YS31-L – Frequently Asked Questions

1) What conductor sizes does the Burndy HYLINK copper compression splice come in?
Two sizes are offered: a 350 kcmil version (MPN YS31-L) and a 600 kcmil version (MPN YS36L). Both are copper compression splices with an electro-tin plated finish. Match the size to the conductor you are joining, and note these are copper connectors for copper conductors, not aluminum or bimetallic.
2) Can I use a Burndy HYLINK copper splice on a 15kV or 25kV medium-voltage cable?
Yes. The HYLINK splice carries a 600V to 35kV rating, so 15kV and 25kV shielded cable splices are inside its range. The upper limit is 35,000 volts. It is a bare compression connector, so the splice kit or tape/heat-shrink insulation system you build over it has to be rated for the same class.
3) Is this a straight splice or a reducer, and can it join two different conductor sizes?
It is sold as a splice/reducer, but each catalog size lists both barrels at the same conductor size, so what you are ordering is a straight through splice: 350 kcmil to 350 kcmil, or 600 kcmil to 600 kcmil. If you need to step from one conductor size down to another in a single connector, you need a true reducing barrel part, not these.
4) Is the Burndy HYLINK splice UL Listed for an inspected commercial job?
UL Listed and CSA approved, and built to the UL468A-468B standard for wire connectors. Worth knowing for a submittal: it is Listed, not UL Recognized, and it does not carry a cULus or ETL mark, so cite the UL Listing and the separate CSA approval on your paperwork. RoHS compliance status is CM.
5) Why choose a compression splice instead of a mechanical bolted connector for a cable splice?
Compression is what this HYLINK connector is built for: the barrel is crimped with a die tool onto the conductor to form a permanent, low-resistance joint with no bolts to back off under thermal cycling. Mechanical set-screw or bolted splices win where you need a re-enterable connection or you cannot get a hydraulic tool into the position. For a buried, pad-mount, or otherwise inaccessible medium-voltage splice, compression is the usual call.
6) Will a Burndy HYLINK splice fit in a tight handhole or crowded pull box?
It is specified for limited space applications, and the barrel is chamfered rather than square-cut, which eases the conductor into the barrel when you cannot get a straight run at it. The barrel type is standard, so it works with conventional compression tooling and standard die sets rather than requiring a proprietary head.
7) Are these Burndy splices rated for stranded conductor or solid?
The barrels are sized for stranded conductor, listed as 350kcmil (Str). At 350 and 600 kcmil you are almost always working with stranded cable anyway, but confirm your conductor class against the Burndy spec sheet before selecting your die.
8) Does the tin plating on this copper splice matter for a damp or direct-buried location?
It does. The copper body is electro-tin plated, which is the standard corrosion-resistant finish for connectors going into wet wells, underground vaults, and pad-mount gear where bare copper would otherwise oxidize at the crimp interface. Tin plate also keeps contact resistance stable over the life of the joint.
9) Do I have to buy Burndy HYLINK splices by the box, or can I get one?
Minimum pack quantity is 1, so single pieces are orderable. Useful if you are stocking a truck with one or two spares in each size rather than committing to a carton of a conductor size you may only splice once.
