Blackburn ASP40 – Frequently Asked Questions
1) What conductor size does the Blackburn ASP40 splice sleeve take?
The ASP40 is sized for 4/0 conductor, and it is a compression splice, so it gets crimped onto the conductor rather than bolted. One sleeve joins two 4/0 ends. It is sold individually, not in a kit or bag.
2) Can I use the Blackburn ASP40 sleeve on copper conductor, or aluminum only?
It is an aluminum-bodied splice with a tin-plated surface. Tin plating is what makes an aluminum connector suitable for use with copper as well as aluminum, since it keeps the aluminum body from contacting the copper directly. Confirm the dual-rated marking stamped on the sleeve for your inspector.
3) Is the ASP40 splice insulated, or do I have to tape or heat-shrink over it?
Bare metal, no insulation on the sleeve. You supply the insulation: tape build-up, heat shrink, or a cold shrink splice kit appropriate to the circuit voltage. Budget for that in the job, because the crimp alone is not a finished splice.
4) What voltage can a Blackburn ASP40 splice be used on?
Rated to 35 kV, so it covers medium-voltage feeder and URD work as well as anything on the line-voltage side. The rating applies to the connector; the insulating system you build over it has to be rated for the circuit too.
5) Why is the ASP40 splice sleeve white, and does the color mean anything?
White is the die-color code marked on the sleeve, which tells the installer which compression die and die index to use in the crimp tool. Match the tool die to the white code rather than guessing, since an undersized or oversized die gives a crimp that will not pass pull-out.
6) Do I need a special tool to install a 4/0 aluminum compression splice like the ASP40?
Yes. This is a compression splice, not a mechanical or set-screw connector, so it needs a hydraulic or battery crimp tool with the correct die for the sleeve's white code. There is no torque-wrench alternative with this body.
7) How is the ASP40 packaged, and what part number do I order?
Order Blackburn part ASP40, sold each. If you are splicing several conductors in a pull box, count one sleeve per splice and order the quantity outright.
8) Where is the Blackburn ASP40 splice made?
Manufactured in Mexico. That is the country of origin a government or institutional buyer needs for trade-compliance and procurement paperwork.
