CUSTOMER REQUEST:

We were asked which solution to adopt when connecting, for example, a transformer to a busbar trunking system or an alternator to a low-voltage switchboard. The request concerned the need for joints capable of adapting to the system without hindering movement and without risking damage to the components. In these situations, rigid bars are the least suitable choice.

OUR SOLUTION:

The most suitable product is the flexible joint (special connections):

• Braided
• Thin laminated

Certain aspects must be taken into consideration, specifically:

• BRAIDED FLEXIBLE JOINT: capable of absorbing small movements in space (for example, vibrations generated by a transformer or an alternator).

• FLEXIBLE LAMINATED JOINT: mainly used when movements occur along a single direction—that is, the length of the joint.

The dimensions of the elements that make up the joint define its flexibility:

• Typical thickness values for individual laminates range from XNUMX mm to XNUMX mm The thickness of the individual sheets ranges from 0,05 mm to 0,2 mm;
• The same values apply to the wire diameter in the case of braided joints.The same values apply to the wire diameter in the case of braided joints.

Lower values mean a more flexible joint, but also a more expensive one.
Since every system is different, these joints are manufactured according to the specific needs of each customer.
There are various manufacturing techniques for flexible joints, starting with the terminals, which can be:

• Crimped into a small tube for braided joints in the case of a braided joint
• Press-welded for laminated joints in the case of a plate joint

Lower values ​​mean a more flexible, but more expensive, joint.
Since each system is different from the other, these joints are made according to the individual needs of the customer.

The conductor itself can take various shapes, in bare or tinned copper, with or without insulation. In some cases, a preferential bend can also be applied to the joint so that it operates exactly as designed. forms the conductor's own can be varied, in red or tinned copper, with the presence of isolation or less. In some cases, it is also possible to give a crease preferential to the joint, so that it works according to design.

ADVANTAGES OF FLEXIBLE JOINTS:

• High ampacity in compact solutions: on average, a power joint has a cross-section between XNUMX mm² and XNUMX mm², with current-carrying capacities that can exceed XNUMX A per joint. For even higher currents, two or more joints can be used in parallel. High ampacity in compact solutionson average, a power joint has a cross-section between 1000 mm² and 2 mm², with current-carrying capacities that can exceed 2000 A per joint. For even higher currents, two or more joints can be used in parallel.
• Ease of installation:no need to crimp lugs, and being custom-made, installation is quick and straightforward. This results in significant overall cost savings for the solution.

Pre-planning the correct position between the operating machine and the distribution system is essential to ensure the joint works properly and achieves long service life, as is calculating the correct joint length. TEKNOMEGA offers its expertise to cooperate with the final customer in the design of the flexible joint.

TEKNOMEGA makes its experience available to collaborate in the design of the flexible joint directly with the end customer.
