The Split Bolt Connector is a robust fastening device crafted from high-strength, high-copper alloy, offering exceptional corrosion and cracking resistance. Its large thread design ensures easy and firm installation of the clamp, maintaining a secure connection for the main branch. Available in standards to accommodate either 2 or 3 cables, distinguished by the suffix “-3” for the triple cable version.
| Model | Cable range |
|---|---|
| T/J-10 | 6~10mm² |
| T/J-16 | 11~16mm² |
| T/J-25 | 17-25mm² |
| T/J-35 | 26~35mm² |
| T/J-50-70 | 40~70mm² |
| T/J-90-120 | 75~120mm² |
One of the main advantages of a Split Bolt connector is its ability to provide a low electrical resistance connection. The secure and tight connection between wires minimizes loss of energy by heating and ensures an efficient transfer of electricity. That’s particularly important in high power systems where any extra resistance may result in significant losses. In addition, the connector also offers a great current capability, allowing it to be used in applications that require high levels of electric current.
The main purpose of a Split Bolt connector is to join two or more copper or aluminum wires, creating a solid, low-resistance electrical connection.


When using a Split Bolt Connector, it is critical to follow a few important steps:
1 – Make sure the wires are clean and free of any coating or corrosion. This can be done using an adequate wire brush or a wire cleaner. Then insert the wires into the connector slot ensuring they fit properly and that there is electrical contact between them.
2 – After inserting the wires, tighten the connector screw using the correct wrench. It’s important not to overtighten, as this could damage the wires or the connector itself. The goal is to obtain a tight enough grip to ensure a secure connection, without excessively compress the wires. Check the manufacturer’s instructions to determine the proper tightening torque for the specific connector being used.
3 – After installing the Split Bolt connector, it is recommended to perform a continuity test and resistance to ensure the connection is working properly. This can be done using a multi-meter or other suitable test device. Check that there is no loss of resistance and that the connection is transmitting electricity efficiently.
