Blackburn ASC 1250-6.5 TN – Frequently Asked Questions
1) What conductor size does the Blackburn ASC 1250-6.5 TN compression sleeve splice?
The Blackburn ASC 1250-6.5 TN is an aluminum compression sleeve sized for 1250 KCMIL conductor, joining two conductor ends in one splice. The sleeve body measures 6.5 inches.
2) Can I use this aluminum sleeve on copper conductors, or is it aluminum only?
It is an aluminum-bodied sleeve with a tin-plated finish, which is the standard construction for dual-rated aluminum-to-copper compression connectors. Tin plating is what keeps the aluminum barrel from galvanic attack when copper is inserted. Confirm the AL9CU marking stamped on the barrel of the sleeve you receive against the conductor metal you are splicing.
3) Does this splice come insulated, or do I need to cover it after crimping?
No insulation on this one. The ASC 1250-6.5 TN is a bare tin-plated aluminum barrel, so the splice has to be insulated in the field after crimping, typically with heat shrink tubing or tape rated for the circuit voltage.
4) Does this 1250 KCMIL compression sleeve meet ANSI C119.4 for underground and service connectors?
Yes. The sleeve is built to ANSI C119.4, the standard covering electric connectors for use between aluminum-to-aluminum and aluminum-to-copper bare overhead conductors. That is the reference a utility or institutional spec usually calls out for a compression splice of this class.
5) Is a compression sleeve the right choice for a 1250 KCMIL feeder splice, or should I use a mechanical bolted connector?
A compression sleeve like the ASC 1250-6.5 TN is the choice when you want a permanent, low-profile splice that can be taped or heat shrunk and buried in a pull box or duct. It needs a hydraulic crimping tool with the correct die and cannot be taken apart afterward. A bolted mechanical splice is what to use instead if you need to reopen the joint later or have no crimper on site. At 1250 KCMIL the compression joint also gives you a smaller overall diameter, which matters when the splice has to fit inside a conduit body or wrap in a cable.
6) Is the Blackburn ASC 1250 sleeve made in the USA for Buy American jobs?
Country of origin is the United States, which is what government, school, and transit buyers need on record for domestic-preference procurement. The exact part number to put on the submittal is ASC 1250-6.5 TN.
7) How is the Blackburn ASC 1250-6.5 TN sold, by the each or in bags?
Sold each. One ASC 1250-6.5 TN part number gets you one 6.5 inch sleeve, which splices one pair of conductor ends, so order one per splice and plan a spare if you are making up several phases.
