4. Opsætning og installation

Follow these steps for proper installation of the copper bolted coupler:

1. Prepare Conductors: Ensure the ends of the conductors to be joined are clean, free of insulation, and properly sized for the 3-1/2 inch coupler. Remove any burrs or sharp edges.
2. Position Coupler: Separate the two halves of the coupler. Place one half around one conductor end and the other half around the second conductor end, ensuring the conductors meet within the coupler's center.
3. Justér og fastgør: Align the two halves of the coupler over the conductors. Insert the bolts through the designated holes, ensuring washers are placed under the nuts.
4. Spænd boltene: Gradually tighten the nuts in an alternating pattern to ensure even pressure distribution. Use a torque wrench to tighten to the manufacturer's recommended torque specifications (if available, otherwise tighten securely to prevent loosening). Over-tightening can damage the coupler or conductors; under-tightening can lead to poor electrical contact.
5. Inspicer forbindelse: After tightening, visually inspect the connection to ensure the conductors are fully seated and the coupler is securely fastened.

5. Driftsprincipper

The Burndy NS2121 Copper Bolted Coupler functions as a permanent mechanical and electrical connection for conductors. Once properly installed and tightened, it provides a low-resistance path for electrical current, ensuring continuity and integrity of the circuit. No active operation is required after installation.

6. Vedligeholdelse

Regular inspection and maintenance can prolong the life and ensure the reliability of your electrical connections.

• Visuel inspektion: Periodically inspect the coupler for signs of corrosion, discoloration, or physical damage.
• Tæthedskontrol: Over time, vibrations or thermal cycling can cause bolts to loosen. Periodically check the tightness of the bolts and re-torque if necessary, ensuring power is disconnected first.
• Rensning: If necessary, clean the exterior of the coupler with a dry, non-abrasive cloth. Do not use harsh chemicals.

7. Fejlfinding

If issues arise with the electrical connection, consider the following:

• Poor Electrical Contact: This can be caused by loose bolts, corrosion, or improper conductor preparation. Ensure bolts are tightened to specification and conductors are clean.
• Overophedning: An overheating connection indicates high resistance, often due to loose connections or inadequate contact area. Disconnect power and re-inspect the installation.
• Fysisk skade: If the coupler shows signs of cracking, bending, or severe corrosion, it should be replaced immediately.
