मुख्य विशेषताएं और सेवाएं

अनुकूलन:

1. Parameter and material selection

• Conductive material: Electrolytic copper (purity ≥99.9%) or aluminum, copper foil thickness range 0.03-0.3mm, aluminum needs to meet the tensile strength ≥379N.
• Insulation material: choose polyimide (PI, temperature resistance >200°C) or polyester (PET, low cost and high CTI) according to the demand of temperature resistance, and the flame retardant grade reaches UL V0.
• Structural design: support L-type, U-type and other shaped customization, flexible busbar for dynamic scenarios (e.g. rail transit), rigid busbar for fixed installation (e.g. substation).

2. Process optimization

• Lamination parameters: Adjust temperature (160-180°C), pressure (6-10MPa), time, etc. through experimental verification, combined with vacuum pumping (≥5 minutes) to avoid air bubbles.
• Integrated design: For example, CCS integrated busbar (FPC+aluminum busbar+blister bracket) can replace the traditional wiring harness to achieve automated assembly and space optimization.

3. Special Demand Response

• High temperature/low inductance: 220°C resistant insulating material and low dielectric binder for SiC/GaN power modules.
• Intelligent monitoring: Integrated flexible circuit and thermal sensor to realize real-time monitoring of battery pack voltage and temperature.

विनिर्माण क्षमताएं:

1. Production capacity scale: Annual production capacity reaches more than 300,000 pieces of traditional composite busbars and 1,000,000 pieces of integrated busbars (upgraded to 2,000,000 pieces after newly added production lines).
2. Production process efficiency: Adopting automated hot press laminating production line, it supports the delivery of large-volume orders, and the cycle time can be shortened to 24 hours (for urgent orders

परीक्षण और गुणवत्ता आश्वासन:

अक्सर पूछे जाने वाले प्रश्नों

Q1: What are the advantages of laminated busbar over cable?
A: Laminated busbar has higher current density (up to 2-3 times that of cable) and no skin effect, which makes it suitable for high-frequency scenarios.

Q2: How to solve the air bubble problem in production?
A: Optimize the vacuum pumping time (suggested ≥5 minutes), control EVA water content ≤0.3%, and use surface embossed film to enhance the exhaust.

Q3: What is the selection basis of flexible busbar and rigid busbar?
A: Flexible busbar is suitable for dynamic environment (e.g. rail transportation), and rigid busbar is used for fixed installation scenarios (e.g. substation).

Q4：Insulation material choose PET or PI?
A: PET has low cost and high CTI (for high voltage), PI has better temperature resistance (>200°C) and is suitable for welding scenarios.

Q5: How to maintain the laminated busbar?
A: Regular infrared temperature measurement (hot spot ≤70°C), clean insulation surface, and voltage resistance retest every 5 years.
