Blackburn ACJ556 – Frequently Asked Questions
1) What is the Blackburn ACJ556 compression splice used for?
The ACJ556 is a full tension aluminum compression splice for joining two runs of 556 conductor in an overhead or service application. It joins two conductors, one entering each end of the sleeve, and the connection is made by compressing the barrel with a die tool rather than by bolting. The body measures 9-9/16 inches, so allow that much straight, accessible conductor length at the splice point plus room to swing the crimp tool.
2) Does the Blackburn ACJ556 splice meet a connector standard for utility work?
It is built to ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors in overhead and underground distribution. That is the reference most utility and line-crew specifications call out for a compression splice, so it can be cited directly on a submittal.
3) Is the ACJ556 a full tension splice or just a jumper connector?
Full tension. The ACJ556 is a tension compression splice, meaning it is intended to carry the mechanical pull of the conductor across the joint, not just the current. A non-tension or jumper type connector will not hold line tension and should not be substituted in a span.
4) Can I use the Blackburn ACJ556 on aluminum conductor, and is it the right size for 556?
Yes on both counts. It is an aluminum bodied splice sized for 556 conductor, which is the 556.5 kcmil ACSR/AAC family commonly used on distribution. Conductor size has to match the splice; a 556 splice will not develop full tension on a smaller or larger conductor.
5) Does the Blackburn ACJ556 come insulated, or do I have to cover it after crimping?
It is a bare aluminum splice with no insulation on the body. Any covering, tape, or insulating boot required by the application has to be ordered separately and applied after the crimp.
6) Is the ACJ556 sold individually or in a box quantity?
The ACJ556 is sold each, one splice per unit, so order one per joint you are making. There is no carton or bag multiple to work around when you are counting up a job.
7) Where is the Blackburn ACJ556 made? I need country of origin for a procurement record.
Country of origin for the ACJ556 is Mexico. The manufacturer part number for the record is ACJ556.
