Copper Tube In-Line Connectors
Copper Tube In-Line Connectors
Frequently Asked Questions
A copper tube in-line connector joins two cable ends together in a straight line, allowing continuous current flow between two separate conductors without needing to route the cable through a screw, stud, or terminal block.
Unlike ring or fork terminals that attach a single wire to a fixed point like a bolt or stud, an in-line connector links two cable ends directly to each other, making it ideal for cable splicing and extension rather than point termination.
They are widely applied in underground cable joints, overhead line splicing, industrial power cable extensions, generator and substation wiring, and repair work where two cable segments need to be electrically and mechanically joined.
Most in-line connectors feature a seamless copper tube barrel with two open ends, allowing cable conductors to be inserted from both sides and crimped separately, distributing mechanical stress evenly across the joint.
A hydraulic crimping tool with dies matched to the connector's outer diameter is recommended, with crimps applied at multiple points along each side of the barrel to achieve a low-resistance, vibration-resistant joint.
Yes, though for outdoor or underground use, additional protection such as heat-shrink tubing, resin filling, or joint kits is recommended to guard the connector against moisture, dust, and corrosion over time.
