Overview

The conductive tube features a special-shaped aluminum profile structure, which significantly increases the conductive heat dissipation area. This design reduces the influence of the skin effect, enhancing the tube's flow and heat dissipation ability. The benefits of this unique structure include making it an ideal choice for specific applications. Our product features advanced silver plating technology, a testament to our commitment to quality. This technology increases the surface adhesion of the silver plating layer, ensuring the thickness and hardness requirements are met. With appropriate contact pressure, the wear resistance of its contacts is improved, guaranteeing that the silver plating layer will not fall off even after long-term work, providing peace of mind for your long-term investment. The soft connection, made of copper, features a conductive contact surface plated with silver. This design ensures good conductivity and strong flow capacity.

Additionally, the surface of each layer of copper tape is tinned, enhancing its corrosion resistance. The benefits of this design include specific benefits, making it an excellent choice for specific applications. Our product's contact finger, a rod-shaped self-supporting contact finger made of copper alloy, is a symbol of reliability. With its high elasticity and conductivity, it ensures stable contact pressure that remains consistent even during long-term operation, providing reassurance of the product's reliability. All the conductive contact surfaces are coated with electric compound grease, and the exposed joints of the fixed contact conductive surfaces are sealed with a waterproof sealant to prevent oxidation and electrochemical corrosion of the conductive surfaces. We also adopt a fully sealed bearing seat to ensure long-term reliable operation.
