Why Top EV Harness Assemblers Choose Our Charging Cables: Compliance, Easy Stripping & Superior Thermal Control

Q1: What international standards and certifications do your raw bulk cables comply with?

A: Our bulk EV charging cables fully comply with key global standards, including EN 50620 / IEC 62893 (for European markets), UL 62 / UL 2263 (for North America), and GB/T 33594. We provide complete CB reports, CE declarations, UL file numbers, and RoHS/REACH compliance documentation with every batch to ensure zero clearance hurdles.

 

Q2: How do your cables perform during automated assembly and terminal crimping?

A: Designed specifically for wire harness assemblers, our cables feature precise outer diameter (OD) tolerances and easy-stripping outer jackets. The concentricity exceeds 85%, preventing blade damage to inner insulation during automatic stripping. High-purity fine-copper conductor stranding ensures stable crimping resistance and high pull-out force.

 

Q3: How do you address thermal management for high-power / fast-charging applications?

A: We use 99.99% oxygen-free copper (OFC) to minimize internal resistance. Combined with high-thermal-grade TPU/TPE insulation materials, our cables demonstrate exceptionally low temperature rise (Delta T) even under continuous 32A/63A AC charging or high-current DC fast-charging conditions, preventing thermal throttling.

 

 

Q4: Can your cable jacket materials withstand extreme environmental conditions?

A: Yes. We offer premium TPU and cross-linked TPE jackets engineered for harsh outdoor deployments. They feature superior resistance to UV radiation, ozone, oil, hydrolysis, and microbial attack. Our cables maintain structural flexibility without cracking in temperatures ranging from -40°C to +105°C.

 

Q5: Do you offer custom conductor configurations or liquid-cooling channels?

A: We provide full OEM/ODM options for raw cable constructions. This includes adding auxiliary signal wires (CP/PP), customized shielding layers (braided or aluminum foil), specialized jacket colors/marking, and advanced liquid-cooling cable architecture for ultra-fast DC charging systems.

 

Q6: What is your typical MOQ and delivery lead time for bulk cable orders?

A: Standard cable specifications are available with an MOQ starting at 1,000 meters per specs. Production lead time is typically 15–20 business days after sample approval. We support full drum packaging (e.g., 500m/1000m wooden spools) ready for automatic processing lines.
