Tubular compression connector for splicing copper power cables, insulatable with tape or heat-shrink tubing.

The tubular splice connector joins two copper cable ends butt-to-butt through a tinned-copper barrel crimped by compression, per UL 486A-486B. The finished splice is insulated with self-fusing tape or heat-shrink tubing until the cable's insulation level (600 V) is restored.
The tubular splice connector is a compression barrel used to join ends of copper power cables in repairs, extensions and electrical installations where mechanical and electrical continuity are required. Unlike the copper compression lug, it does not terminate the cable in an eye for a bolt; it joins cable to cable and must then be insulated according to the circuit service level. At TECTUL it is quoted for copper power splices, insulatable with tape or heat-shrink tubing according to the application. Correct selection depends on conductor gauge, cable type, space in the raceway or panel and available crimping tool. It should not be used as a substitute for an eye lug or as an improvised adapter for aluminum.

| Step | Detail |
|---|---|
| 1. Stripping | To half the barrel length, without nicking the copper |
| 2. Insertion | Each cable to the center stop of the connector |
| 3. Crimping | Die of the size; 2 or more compressions per side, from center outward |
| 4. Insulation | Heat-shrink with typical 3:1 shrink ratio (catalogs) or self-fusing tape + jacket tape |
| 5. Verification | Embossed die code and pull check |
Splices per UL 486A-486B: the connector-die-tool system must be the one the manufacturer specifies so the joint keeps the conductor's ampacity.
It is quoted via WhatsApp according to gauge, quantity and availability. We do not publish or invent prices for this industrial line.
It is used to join two ends of cable by compression, especially in repairs, extensions and power conductor splices.
The tubular connector joins cable to cable; the copper compression lug terminates the cable in an eye to fasten it to a bolt or busbar.
The ends are stripped, inserted into the barrel, crimped with the correct die and then the splice is insulated according to the project procedure.
It should not be assumed. This page focuses on splices for copper cables; for aluminum or transitions another compatible accessory must be validated.
Cable gauge, number of splices, conductor type, installation location and whether you need a recommendation for subsequent insulation.
Crimped for power: die-calibrated compression gives a permanent full-section joint that does not loosen under vibration or thermal cycles; screw connectors remain for accessible control taps.
With heat-shrink tubing sized to the splice diameter (typical 3:1 shrink ratio) or with self-fusing rubber tape plus protective tape, rebuilding at least the original 600 V insulation level.
