Yuzhan holds IATF 16949 certification and follow the ISO 9001 quality control system as well as ISO 14001. Our specialized technology ensures safety, durability, and strict compliance with all applicable industry standards

We have long been dedicated to the rail transit wiring harness sector, and currently deliver integrated solutions that combine high quality, excellent value, and exceptional reliability to seating systems, thermal management systems, security inspection systems, and core equipment manufacturers.

Manufacturing Capabilities​

Yuzhan combines cutting-edge technologies with premium craftsmanship to deliver precisely engineered solutions customized to your requirements.

Services

We offer turnkey solutions, including:

  • Full-scope engineering and material procurement solutions
  • Cut and shrink tubing
  • In-line engineering and assembling
  • Molding and overmolding
  • Testing and quality assurance
  • Tinning and soldering
  • Wire crimping and braiding
  • Value-added services, such as quote response within one day, customized wire codes, product testing, and visual inspection
Technical Specifications

The wiring harnesses we produce have the following features:

  • Material Quality:We guarantee no low-quality or counterfeit materials. Compliance documents available for all materials.
  • Precision manufacturing:Extremely high requirements are placed on cutting tolerances, crimping processes, etc., to ensure dimensional accuracy and connection reliability. Wire diameter deviations must be controlled within standard limits.
  • Comprehensive protection:Shielded layers or twisted pairs are used for signal lines susceptible to interference. Corrugated tubes or tape protect the areas where the wiring harness contacts the vehicle body. Heat-shrink tubing secures the branch points. High-voltage harnesses also require stringent sealing design.
  • Clear identification:Clear model numbers, specifications, and production lot numbers are marked on both wires and connectors to ensure traceability.
  • System certification:Yuzhan strictly implement IATF 16949 and follow the ISO 9001 quality control system as well as ISO 14001.
Safety Testing

Yuzhan adheres to globally recognized quality management and testing systems—from raw materials to final verification—guaranteeing long-term reliability of our automotive wiring harnesses under extreme conditions and meeting our “zero defect” quality objective.

  • Mechanical performance testing:The structural strength and connection durability of the wiring harness are verified through tests such as vibration, tensile strength, and insertion/withdrawal cycle life
  • Electrical performance testing:Ensures that parameters such as insulation, withstand voltage, voltage drop, temperature rise, and electromagnetic compatibility (EMC) meet the requirements.
  • Environmental adaptability:Tests including thermal cycling, damp heat aging, salt spray corrosion, chemical solvent immersion, and water/dust protection (e.g., IP67/IP6K9K) ensure that the wiring harness is capable of withstanding a wide range of harsh environments.
Process

Utilizing state-of-the-art facilities, our skilled technicians deliver superior products adhering to the highest standards of quality, hygiene, and durability.

Design review → materials preparation → assembly documentation → inbound inspection → prototyping → production → volume → assembly test

Certifications

Frequently Asked Questions

Is Yuzhan certified under the IRIS (ISO/TS 22163) railway quality management system?

We are currently in the process of obtaining IRIS certification and expect to complete it by 2027. In the meantime, our quality management system is fully aligned with ISO 9001,IATF16949 and all railway projects follow IRIS‑based process controls.

Can Yuzhan provide full traceability docs (material batches, in-process checks, final test reports)?

Absolutely. Traceability is standard for us – material lots, in‑process checks, and final test reports are all documented and available per project.

Can Yuzhan manufacture the harness if I send a photo of a vintage wire harness?

Sorry, but no. We are a B2B wire harness manufacturer, accepting and manufacturing orders in bulk. We do not manufacture a single-wire harness.

How long does it take to ship my custom wire harness?

Typical lead times range from 2 to 6 weeks, based on order quantity and the level of customization. Expedited options are available for urgent requests to accommodate specific delivery schedules.
