Parallel Groove Clamps(Joint Transition Connectors,Copper Connection Terminals, Clamps)

Pure copper material and high electrical conductivity:

It is made of T3 high-quality red copper or T2 thickened red copper, with a purity of over 99.9%, ensuring that the current transmission efficiency is increased by more than 30% compared to aluminum baseline clips. The high electrical conductivity of copper (with a resistivity of approximately 0.017Ω·mm²/m) effectively reduces line losses, making it particularly suitable for high-frequency current or high-current scenarios.

Toothed interlocking and arc clamping structure:

The internal toothed protrusion design can penetrate the oxide layer on the surface of the wire, forming direct metal contact. The contact area is 40% larger than that of ordinary wire clamps. In combination with the arc-shaped surface clamping structure, by applying uniform pressure at multiple points, the wire can maintain stable creep performance under temperature fluctuations ranging from -30℃ to 90℃.

Integrated components and anti-corrosion processes:

The main body of the wire clamp and the pressure block are made by integral die-casting process, avoiding the problem of easy part dropping in the split design. The bolts and metal parts have all undergone hot-dip galvanizing treatment. Salt spray tests show that its corrosion resistance is twice as good as that of the ordinary nickel plating process, making it suitable for humid or industrially polluted environments.

Multi-specification adaptation and standardized design:

We offer various models ranging from JBT-0 to JBT-4, which are compatible with copper stranded wires or copper core cables ranging from 16 to 240mm². The height of the wire clamp is adjustable (for example, the height of the JBT-44 type can reach 108mm), supporting the connection of conductors of the same diameter or different diameters, meeting the diverse requirements of overhead lines of 10kV and below.

Excellent electrical conductivity:

The red copper material itself has excellent electrical conductivity. Coupled with a relatively small contact resistance, it can significantly reduce the loss during the transmission of electrical energy, decrease heat generation, and enhance the efficiency of power transmission.

Easy installation:

The installation method is simple, no special tools are required, which can save installation time and labor costs and improve construction efficiency.

Good protective performance:

It can be used in conjunction with an insulating cover to prevent dust and water splashes, effectively protecting insulation and enhancing the operational safety of the wire clamp in harsh environments.

Strong corrosion resistance:

Copper material is less prone to electrochemical corrosion. Compared with copper-aluminum connection, it is more suitable for long-term use in various environments and has a longer service life.

Wire connection: It is mainly used for non-load-bearing connection and branching of copper wires in overhead power lines, and can also be used for jumper connection of non-linear poles and towers. It can achieve reliable connection of two copper wires of the same or different specifications.

Electrical transmission: As a power hardware, it can ensure that the current passes smoothly at the connection points of the conductors, guarantee the normal transmission of power, and maintain the stable operation of the lines.
