Blackburn ASP350 – Frequently Asked Questions
1) What conductor size does the Blackburn ASP350 splice sleeve take?
The ASP350 is sized for 350 kcmil conductor, which is where the 350 in the model number comes from. It's a compression splice sleeve, so both conductor ends go into the barrel and get crimped with a hydraulic or battery compression tool using the die matching the sleeve.
2) Can I use an aluminum splice sleeve like the Blackburn ASP350 on copper conductors?
Yes. The ASP350 barrel is aluminum with a tin plating, and tin plated aluminum compression connectors are the standard dual-rated choice for aluminum or copper. The tin plate is what keeps the aluminum barrel from reacting directly against copper. Use the correct compression die and an oxide inhibitor on aluminum conductor.
3) Is the Blackburn ASP350 splice rated for medium voltage cable?
It carries a 35 kV voltage rating, so it's suitable for medium voltage splicing up to 35 kV when installed inside a properly rated splice kit or tape/shrink rebuild. The connector rating alone does not make the splice 35 kV; the insulation and shielding system you build over it does.
4) What does the brown color on the ASP350 splice sleeve mean?
Brown is the color code marking on the barrel, matching the die index for 350 kcmil on Blackburn compression connectors. On the job it's the quick visual check that the installer grabbed the right sleeve and the right die before crimping.
5) Is the Blackburn ASP350 a mechanical set-screw splice or a crimp type?
Crimp. It's a compression splice for wire or cable, so it needs a compression tool and the matching die, not a hex key. If your crew doesn't have a hydraulic crimper on site, a set-screw or mechanical splice connector is the type to look for instead.
6) Does the ASP350 come as a pair or a single sleeve?
It sells as each, one sleeve per unit. A single sleeve joins one conductor run, so a three-phase splice needs three, and four if you're also splicing a neutral.
7) Where is the Blackburn ASP350 made? I need country of origin for a government job.
Country of origin is Mexico. That's the figure to put on Buy American or trade compliance paperwork for this connector.
