Advantages of Combination Cable Clamps
Excellent electrical conductivity: Tight contact, low resistance, and minimal heat generation in the circuit.
Easy to install: Bolted fastening and integrated components prevent loosening or detachment, enabling quick installation.
Wide compatibility: Compatible with both same-diameter and different-diameter wires, offering high versatility.
Secure connection: Uniform clamping force prevents wires from loosening or deforming.
Corrosion-resistant and durable: Made of aluminum alloy, it resists rust and aging, ensuring a long service life.
Removable and reusable: Can be disassembled and reused during maintenance, resulting in low maintenance costs.
Applications of Combination Cable Clamps
-
Suitable for intermediate splicing and branch connections of overhead aluminum stranded wire and steel-core aluminum stranded wire.
-
Can be used for parallel connections and jumper connections of conductors of the same or different diameters.
-
Primarily used in low-voltage distribution lines of 10 kV and below.
-
Suitable for conductor branching, T-connections, and parallel connections on straight poles and tension poles.
-
Can be used in conjunction with insulated sleeves to meet the connection requirements of insulated lines.
-
Suitable for routine connections in outdoor overhead lines and rural and urban distribution networks.

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.
