Product Description

Product Description

The combined wire is a winding wire made of several copper/ aluminum rectangular wires arranged in accordance with the specified requirements and wrapped by specific insulating materials. It is mainly used in the windings of oil-immersed transformers, reactors and other electrical devices. Budweiser Electric specializes in the production of copper and aluminum conductor paper-wrapped wires and combined wires, with accurate product shape, moderate wrapping tightness.

FAQ

Q1: What is combination wire, and why is it used in transformers?
A: A specialized winding wire combining copper and aluminum rectangular strands wrapped with insulating materials (paper/film). It's ideal for oil-immersed transformers, reactors, and electrical devices where thermal stability and cost efficiency are critical. Copper's high conductivity paired with aluminum's lightweight properties optimize performance.
Q2: What are the key dimensions and specifications of your combination wire?
A: 

• Axial arrangement:
  • Width: 4mm × 12.5mm
  • Thickness: 2.5mm × 8mm
  • Width-to-thickness ratio: 6:1 (single conductor)
• Radial arrangement:
  • Width: 4mm × 12.5mm
  • Thickness: 4mm × 9mm
  • Width-to-thickness ratio: 13.5:1 (single conductor)
• Harness size: Width 8mm × 35mm, Thickness 13mm

Q3: How does your combination wire improve transformer efficiency?
A: Reduces eddy current losses by separating copper (high conductivity) and aluminum (lightweight) layers. The moderate wrapping tightness ensures optimal heat dissipation, extending transformer lifespan in high-voltage environments (e.g., power grids, industrial reactors).
Q4: What insulation materials do you use, and why?
A: Options include:

• Paper-clad copper/aluminum tape (for traditional oil-immersed systems).
• Film-wrapped copper/aluminum tape (enhanced dielectric strength for modern HV/LV transformers).
  Both meet IEC 60085 and GB/T 11293 standards.

Q5: Can you customize the wire dimensions or conductor ratios?
A: Yes! We adjust:

• Strand numbers (e.g., 2, 3, or 4 conductors).
• Width-to-thickness ratios (e.g., 6:1 axial, 13.5:1 radial).
• Insulation types (paper, polyester film).
  Contact us for specs beyond standard ranges (e.g., non-standard widths or thicknesses).

Q6: Why choose combination wire over single-metal windings?
A: 

• Cost savings: Aluminum reduces material costs vs. pure copper.
• Weight reduction: Lighter than copper-only designs, easing installation.
• Thermal management: Aluminum's lower thermal expansion minimizes stress in oil-immersed systems.

Q7: What industries or applications suit this wire?
A: 

• Power grid infrastructure: Step-up/step-down transformers.
• Renewable energy: Wind/solar farm inverters.
• Industrial machinery: Reactors, rectifiers, and high-voltage motors.

Q8: How do you ensure quality compliance?
A: Every batch undergoes:

• Dielectric strength testing (≥35kV).
• Thermal aging simulation (150°C for 240 hours).
• Dimensional checks via laser micrometers (tolerance ±0.05mm).
  Certified to CCC, CE, and ISO 9001:2015.

Q9: What's the lead time for bulk orders?
A: 

• Standard orders: 15-20 days (MOQ 500kg).
• Custom designs: 25-30 days (with engineering consultation).
• Rush service: 10 days (+20% surcharge).

Q10: Why buy combination wire from a Made in China supplier?
A: 

• 40% lower cost vs. EU/US suppliers.
• Localized manufacturing for fast prototyping.
• Global certifications (supplying Siemens-tier OEMs).
