• Protection grade: IP54 (dustproof and waterproof).

Kuidas tinatatud vasest siinilatti?

1. Copper pretreatment

• Drawing and annealing: High purity copper rods are drawn to the target wire diameter, and the annealing temperature is controlled at 400-550°C to optimize the ductility.
• Acid washing to remove oxidized layer: Use acidic solution (such as hydrochloric acid or flux) to remove surface oxides to ensure plating adhesion.

2. Tin plating process

• Hot-dip plating/electroplating: Copper wires are immersed in a tin furnace (250-260°C) or electroplating bath to form a uniform plating layer. Cooling and cleaning: Water or air cooling is used to remove the surface oxides.
• Cooling and Cleaning: After water or air cooling, clean the residue, add shaft guide oil to prevent the generation of tin ash.

3. Post-treatment and inspection

• Annealing: 600-800℃ annealing to eliminate stress and improve flexibility.
• Quality inspection: including conductivity test, plating thickness measurement (such as X-ray fluorescence method) and corrosion resistance test.

Kui paks on tinaga kaetud vasksiin?

• Conventional applications: 0.5-2.0μm, balancing cost and performance.
• High protection requirements: such as power equipment or marine environment, the thickness of the coating can be more than 6μm.

Miks vasest siinilattide tinatamine?

Vasest siinilattide tinakatmisel on mitu eesmärki. Esiteks suurendab see vase korrosioonikindlust, pikendades selle eluiga ja tagades pikaajalise toimimise, eriti niiskes või söövitavas keskkonnas. Teiseks tagab tinatamine siledama pinnaviimistluse, vähendades pinna ebatasasusi ning parandades elektrilist kontakti ja juhtivust. Lisaks võib tinatamine takistada vase pinna oksüdeerumist, säilitades selle terviklikkuse ja elektrilised omadused aja jooksul. Üldiselt pakub tinatamine vasest siinivardade vastupidavust, juhtivust ja töökindlust erinevates rakendustes.

Tinaga kaetud vasest siinivardad pakuvad mitmeid eeliseid:

1. Anti-oxidation and corrosion resistance

• The tin layer isolates copper from oxygen and moisture, avoiding the generation of copper green (Cu₂(OH)₂CO₃) with poor electrical conductivity, and prolonging the life of the busbar.

2. Improve conductive stability

• Tin plating reduces contact resistance (by about 10-15%), especially in high-frequency or high-current scenarios to reduce energy loss.

3. Enhanced solderability

• Tin has a low melting point (232°C), which makes solder joints easier to form and stronger, making it suitable for automated soldering processes.

4. Adapt to complex environments

• Resistant to salt spray, acid and alkali, suitable for chemical, marine and other corrosive environments.

5. Economy and environmental protection

• Compared with pure silver plating, tin plating cost is lower, and tin non-toxic in line with RoHS standards.

Tin-plated copper bus bars application:

• Power system: transformer, switchgear connection, extra high voltage transmission.
• New energy vehicles: battery pack connection, charging pile internal conductor.
• Communication equipment: 5G base station, data center high frequency signal shielding.
