Blackburn PTC 750-6536 CU TAPERED COMP SPLICE 750

It is a tapered copper compression splice sized for 750 kcmil conductor, which is what the 750 in the model designation refers to. It joins two conductors end to end, so both sides must be 750 kcmil copper.

It ships bare. No insulation is supplied on the barrel, so the installer covers the completed splice with tape, heat shrink, or a cold shrink sleeve per the application.

The barrel measures 4.280 inches long overall, so plan on roughly that much straight, unobstructed run plus room for the crimp head to travel around it. In a pull box or handhole, that working clearance is usually the limiting factor, not the splice itself.

No. This is a copper-only tapered compression splice. Aluminum or mixed copper-to-aluminum runs need a connector rated AL9CU or an aluminum-bodied splice with the correct oxide-inhibiting compound.

The PTC 750 splice is rated for harsh environments and the copper barrel is tin-plated, which resists corrosion and oxidation. Since it comes with no insulation, any wet or buried application still depends on the sealing system you install over it.

A compression splice is crimped once with a hydraulic tool and stays put, with no bolts to re-torque and a lower profile than a bolted connector, which matters in a crowded service entrance or pull box. The tapered ends also ease the transition for taping or shrink sleeving. A mechanical bolted splice is the better pick when you need to make up the joint with hand tools or want it reopenable later.

Sold each, as a single splice. Order one per joint, and remember a 3-phase plus neutral service entrance splice-out needs four.

Country of origin on the PTC 750 tapered compression splice is the United States, which is the record procurement typically needs for Buy American or BABA documentation on public work.
