FAQ
Q: Can parallel groove clamps be used for load-bearing applications?
A: No. Parallel groove clamps are only for non-load-bearing branch connections. Conductor tension must be borne by tension clamps or suspension clamps.
Q: Can copper and aluminum conductors be directly connected with JB clamps?
A: No. Copper-aluminum transition parallel groove clamps JB-TL type must be used to prevent electrochemical corrosion.
Q: Is tighter bolt fastening better?
A: No. Over-tightening will cause clamp deformation and cracking, conductor damage. Must tighten according to specified torque.
Q: What causes parallel groove clamp heating?
A: Possible causes include: contact surface oxidation not thoroughly cleaned, loose bolts, clamp model not matching conductor, overload operation.
Q: Can parallel groove clamps be reused?
A: Yes, but need to check clamp for deformation or cracks, re-clean oxide layer, and use new bolts.
Q: Why apply conductive grease during installation?
A: Conductive grease can fill microscopic voids, reduce contact resistance, prevent oxidation corrosion, and reduce heating.
