How To Maintain A Very Low Contact Resistance In Suspension Clamps?

To avoid high resistance between the suspension clamp for abc cable wire and the conductor, key lies in controlling several aspects of the construction and maintenance process. The following content, based on industry practice and standards, proposes specific feasible solutions:

Materials and Contact Surface Treatment

Use a high-conductivity metal material for the contact components between the suspension clamp for lt ab cable wire and the conductor. The metal contact surface should be flat, free of oxide scale, and free from mechanical deformation. If the conductor sheath or suspension clamp wire already shows slight oxidation or contamination, it should be thoroughly cleaned before installation to eliminate any tiny gaps or contaminant layers that could cause localized resistance increases.

Clamping Force and Mechanical Fastening Requirements

The clamping force of the fiber suspension clamp wire must be sufficiently stable to maintain a good crimp between the conductor and the cable suspension clamp wire. The clamping fasteners should be tightened to the designed torque value and checked regularly. Too loose a clamp may cause poor contact, while too tight a clamp may damage the conductor. Adjust the clamping force according to the cross-sectional area of ​​the conductor to ensure long-term stable contact.
