Analysis of Core Knowledge in Braided BusBar Industry

The basic material of Copper Braided Flexible Connectors is copper, which is prone to oxidation and formation of copper green when exposed to air. This not only reduces conductivity but also poses certain safety hazards; Tin plated copper braided flexible connections are made by coating a thin layer of tin on the surface of a copper substrate. Tin forms a stable tin dioxide film in the air, which can effectively prevent further oxidation of copper materials. It is non-toxic and odorless, suitable for use in damp, dusty basements, roofs, and important electrical equipment. From the perspective of conductivity, the DC resistivity of tin is higher than that of copper at 20 ℃. The overall resistance of Tinned Copper Braid Earthing Tape will slightly increase, and the current carrying capacity at the same voltage will slightly decrease. Although the silver plated version has better oxidation resistance and conductivity, the cost is higher. In conventional small-sized products, the purchase price difference between purple copper and tin plated copper braided flexible connections is relatively small, and can be flexibly selected according to the usage environment.

High quality Flexible Braided Custom Connectors must meet various appearance and structural requirements, with a smooth and glossy surface, no oxidation phenomena such as blackening or redness, a tightly woven structure, and no problems such as holes, skipped threads, broken wires, or broken strands; The end treatment should be flat and free of pits, with a shiny surface after polishing or electroplating. The cut surface should be smooth like a mirror and the hole wall should be free of burrs. At the crimping point, the Braided Copper Wire should be extruded into a whole structure similar to a copper plate. After cutting flat, there should be no obvious single copper wire to avoid the end from falling off. At the same time, the diameter of the copper wire determines the range of cross-sectional area that can be woven. 0.10mm copper wire is suitable for 4-35mm ², 0.15mm copper wire is suitable for 4-120mm ², and 0.20mm copper wire is suitable for 16-800mm ². The small-sized 2.5mm ² products on the market do not have standardized compatibility and are not recommended for use.

The Low to Medium Voltage Flexible Connectors available in the market are made of three types of materials: copper, copper-clad copper, and copper-clad aluminum. Among them, copper-clad copper and copper-clad aluminum are inferior substitute materials that need to be carefully identified. T2 pure purple copper has a conductivity of ≥ 96%, a DC resistivity of approximately 0.018 Ω· mm ²/m at 20 ℃, an elongation of>35%, and will only melt at 1080 ℃; Copper clad copper is made of brass as the core and coated with thin purple copper on the surface. Its conductivity is only 25% -30% of pure copper, elongation is 18% -25%, and temperature resistance is only 86% of pure copper. When burned with a lighter, it will explode and the cross-section will be brass colored; Copper clad aluminum wire core is white and has poorer performance. Under the same specifications, Braided Flexible Busbars made of pure copper have a heavier weight, which is also an important basis for quickly determining quality. Poor quality materials cannot meet the conductivity and safety requirements of electrical systems, and are prone to faults such as thermal breakdown and open circuits.

Flexible Braided Copper Busbar is mainly used for grounding and cross connection in building electrical and industrial power distribution. Relevant regulations have clear requirements for its usage specifications and scenarios, which is the key to ensuring the safety of electrical systems. In terms of the cross connection of distribution box doors, GB50303-2002 requires that openable doors equipped with electrical appliances use Braided Copper Bus Bar Heat Sink PVC Sleeves. GB50303-2015 has been updated to use yellow green insulated copper core flexible wires with a cross-sectional area of ≥ 4mm ² for connection. The box frame without electrical components can be simplified for grounding, but the grounding of the door body is recommended to be no less than 4mm ² to avoid electric shock or fire accidents caused by leakage.

Be cautious of cutting corners in the engineering procurement of Braided Copper Flexible Wire Connectors. Common problems include replacing large specifications with small ones and tin plated copper with ordinary copper. For example, using 2.5mm ² ordinary copper braided tape instead of 4mm ² tin plated copper braided tape and 6mm ² braided tape instead of 16mm ² tin plated Flat Copper Braides can reduce procurement costs but cannot meet regulatory requirements and usage needs, which can easily lead to electrical safety accidents. When purchasing, it is necessary to clearly indicate the material, specifications, and process requirements, while checking the core indicators such as appearance, structure, and weight of the product to ensure consistency with the contract requirements.

In actual use, precise selection should be made based on the usage environment and connection requirements. Tin plated Flexible Insulated Copper Busbars should be preferred for humid, corrosive, and outdoor scenarios. Copper braided tape should be used for power connections, and copper braided wire should be used for non power connections; Ensure that the crimping is firm during installation to avoid excessive contact resistance and heat generation. Regularly check the surface of the product for oxidation and loose connections, clean the copper green in a timely manner, and take protective measures to ensure the long-term stable operation of the Braided Wire Copper Bus Bar, which plays a core role in flexible conductivity and grounding protection.
