Blackburn ASP30 – Frequently Asked Questions

1) Will the Blackburn ASP30 splice work on 3/0 AWG aluminum conductor?
Yes. The Blackburn ASP30 is sized for 3/0 AWG aluminum conductor, and it's a compression splice, so it's crimped on with a die-driven tool rather than bolted. Body material is aluminum with a tin-plated finish.
2) Can I use this aluminum splice on copper cable, or is it aluminum only?
The ASP30 is an aluminum-bodied splice with tin plating. Tin plating over aluminum is what allows a connector to be used on copper as well as aluminum without galvanic trouble at the interface, which is why utility and industrial aluminum compression connectors are plated. If your job spec calls out a dual-rated AL9CU connector by designation, confirm that marking on the barrel before you crimp, because the rating is stamped on the part.
3) Is this splice rated for 35kV medium-voltage cable?
The voltage rating on the ASP30 is 35 kV, so it suits medium-voltage feeder and utility distribution splicing. The sleeve itself carries no insulation, so the 35kV rating is realized only once you rebuild the insulation and shield over it with a splice kit or tape build-up to the cable's class.
4) Does the Blackburn ASP30 come insulated or do I need to insulate it myself?
It ships bare. Insulation material is listed as none, so the installer covers the finished crimp, typically with a heat-shrink or cold-shrink splice kit rated for the cable class. Order that insulating kit separately.
5) Is this Blackburn splice UL listed for commercial and utility work?
The standards reference on the ASP30 is UL E9809, which is the file the connector is listed under. Institutional and utility specs that call for a listed compression connector are satisfied by that reference, and the file number is what an inspector will look for.
6) What is the manufacturer part number for this Blackburn 3/0 aluminum splice?
Blackburn ASP30. That's the number to quote on a submittal or a reorder for the 3/0 AWG aluminum compression splice sleeve. Country of origin is Mexico.
7) Can I use a compression splice like this in a direct-buried or manhole location?
The aluminum body is tin plated, which is the finish specified for corrosion resistance in damp and buried environments, and compression makes the joint permanent with no bolts to re-torque on a maintenance cycle. Because the sleeve carries no insulation, a buried or submersible application still needs a properly rated splice kit built over it.
8) What is the ruby color on this Blackburn splice for?
Ruby is the color code Blackburn uses on this sleeve so a crew can confirm conductor size and the matching die at a glance on the reel or in the trench. It is an identification aid, not a coating difference. The functional finish is tin plating over the aluminum body.
9) Are these splices sold individually or in a box?
Each. The selling unit on the ASP30 is one sleeve, so you order the exact count your splice locations require rather than a fixed carton.
