Blackburn RCJ397 – Frequently Asked Questions
1) What conductor size is the Blackburn RCJ397 jumper sleeve made for?
The RCJ397 is sized for 397.5 ACSR conductor. It is a compression splice, so it is die-crimped onto the conductor rather than bolted, and it is sold one per unit.
2) Can I use the RCJ397 jumper sleeve to carry full line tension on a span?
No. The RCJ397 meets the ANSI C119.4 40 percent partial tension requirement, so it is a jumper sleeve for slack jumper loops and bus connections, not a full-tension span splice. For a conductor running under full tension, use a full-tension compression splice rated for that duty.
3) Does the RCJ397 splice two conductors together, or is it a terminal?
It joins two conductor ends. The sleeve accepts a conductor at each end of the barrel and is crimped on both sides, making it a two-conductor inline jumper connection rather than a lug or terminal pad.
4) Do I need a hydraulic crimper for the Blackburn RCJ397, or can it be bolted?
Compression only. There are no bolts or set screws on the RCJ397, so installation requires a compression tool and the correct die for the sleeve, working the crimps in sequence along the 7-1/4 inch barrel.
5) Is the Blackburn RCJ397 insulated?
No insulation. The RCJ397 is a bare compression sleeve, so any covering, tape, or cover needed at the connection point is a separate item.
