الشركة الرائدة في تصنيع قضبان التوصيل المرنة المصفحة

In our factory, we specialize in designing and producing high-quality, low-inductance busbars tailored for efficient power distribution. It is made by alternating layers of conductive materials (copper or aluminum) and insulating materials, and is structured with a layer-by-layer parallel distribution, which effectively reduces the distributed inductance of the line (which can be reduced to less than 10.6nH). Its flexible design allows multi-dimensional twisting and bending (bending radius can be up to 5 times the diameter of the conductor), suitable for complex installation environments. With both low impedance and high integration, the product is widely used in new energy, rail transportation and other high-power scenarios.

تصنيف قضبان التوصيل المرنة الرقائقية:

يمكن تصنيف قضبان التوصيل المرنة المطلية على أساس عدة عوامل، بما في ذلك بنائها وتطبيقها وخصائص تصميمها. فيما يلي تصنيف يعتمد على هذه المعايير:

 Structure parameters

• Conductor material: T2 pure copper or 1060 aluminum (surface treatment including tin/nickel/silver plating)
• Flexible conductor: copper wire diameter 1.5-3mm, connection piece thickness 0.1-0.2mm
• Insulation: Polyester (PET, 105°C temperature resistant) or Polyimide (PI, 200°C temperature resistant)
• Flame retardant rating: UL94 V-0 (certified by combustion test)
• Protection grade: IP58 (for humid and high heat environment)

Processing parameters

• Maximum processing size: 1600 x 800mm (hot press sealing/can sealing process)
• Connection: Pressure convex, copper column riveted / welded

Production process

1. Conductor molding

• Copper wire (diameter 1.5-3mm) is made into flexible copper wire by wire drawing process with tin/silver plating on the surface.
• Copper row cut to flexible connecting piece (length 0.2-0.4mm), connecting copper wire by laser spot welding

2. Insulation treatment

• Conductors are laminated and vacuum hot-pressed (2.5 hours hot pressing + 1.5 hours cold pressing) to form an elliptical cross-section.
• Wrapped semiconductor paper inner shield, filled with epoxy resin or silicone

3. Multi-layer encapsulation

• Covered with plastic/rubber insulation, outer shield and jacket (HDPE or ceramic) in sequence
• Passed short-circuit resistance test (Rittal Labs certification)

4. Testing and verification

• Test items include insulation resistance (20MΩ-∞), temperature rise, distributed capacitance/inductance, salt spray test, etc.

Product Advantages

1. Excellent electrical performance

•  Low inductance to reduce surge voltage (reduce power device voltage requirements)
• Uniform capacitance distribution inhibit electromagnetic interference (EMI/RFI reduced by more than 30%)

2. Flexible and reliable structure

• Compensate ±5mm installation error, avoiding copper row stress deformation
• No intermediate connector design, reduce failure points (life expectancy increased by 50%)

3. Environmental adaptability

• Temperature range -30℃ to 105℃ (PI material can reach 200℃)
• IP58 protection level, suitable for underground pipeline corridors, chemical and other harsh environments.

4. Economical and efficient

• Factory prefabricated length up to kilometer (reduce time consuming on-site installation by 60%)
• Support customized design (can be developed by providing drawings or environmental parameters)
