Frequently Asked Questions
What is the minimum bending radius of the harness? Can it be used for wiring in tight spaces?
The minimum bending radius of this harness is 5 times the wire diameter, far less than the 10 times requirement for ordinary PVC wires. Due to the use of multi-strand ultra-fine tinned copper wire stranded structure, the harness has excellent flexibility and can be flexibly routed in tight spaces such as mobile phones, sensors, car door panels, and LED lamps, without core breakage even with frequent bending. For applications requiring a smaller bending radius (e.g., robot drag chains), a high-flexibility drag chain-specific harness can be selected.
What after-sales services are provided after purchasing the harness?
Yingna Technology harness products come with a standard 2-year warranty. Non-human damage within the warranty period is repaired or replaced free of charge. Domestic customers enjoy a 48-hour response and repair completion within 7 working days; overseas customers can arrange DHL/FedEx repair by mail. Products beyond the warranty period are eligible for paid repair services (cost approximately 30~50% of new product). Lifetime technical support is provided, including harness selection consultation, terminal processing solutions, and quality issue diagnosis. Annual framework agreement customers enjoy value-added services such as priority production scheduling, free samples, and factory inspection support.
What is the conductor material of this harness? Bare copper or tinned copper?
This model uses multi-strand tinned copper wire conductors, balancing conductivity and corrosion resistance. Bare copper conductivity is approximately 101% IACS, while tinned copper is about 98% IACS (difference only about 3%). Advantages of tinning: 3~5 times stronger oxidation resistance, better solderability (avoiding soldering issues), and significantly improved corrosion resistance. For high-reliability scenarios such as new energy vehicles and outdoor equipment, tinned copper wire harnesses are recommended.
What is the difference between new energy vehicle harnesses and ordinary harnesses?
New energy vehicle (EV/HEV) harnesses must meet higher standards: ① Temperature rating—battery pack internal temperature can reach 85~150℃, requiring silicone rubber harnesses (PVC cannot meet this);
② Voltage rating—high-voltage connection harnesses withstand 600V~1000V, far higher than ordinary 300V;
③ EMC shielding—high-voltage harnesses require a braided shield to prevent electromagnetic interference (EMC, compliant with CISPR 25 standard);
④ Flame retardancy—VW-1 + low smoke zero halogen (LSZH);
⑤ Vibration resistance—terminal crimping must not loosen under high-frequency vibration (vehicle operation);
⑥ TS16949 automotive quality management system certification. Ordinary harnesses do not meet these requirements and are prohibited for use in new energy vehicles.
Will the harness age after long-term use? How to extend its service life?
Under normal use conditions, the silicone rubber material of this harness has a service life of 10~15 years, while PVC material lasts 5~8 years. Factors affecting lifespan: ① Operating temperature—long-term operation at the rated temperature upper limit accelerates aging (halving lifespan);
② Bending frequency—choose high-flexibility harnesses for frequent bending applications (bending life ≥10 million cycles);
③ Environmental factors—UV rays, ozone, and chemical solvents accelerate silicone rubber outer layer aging. Suggestions to extend life: Leave a 20% margin in operating temperature, avoid contact with chemical solvents, add protective sleeves for fixed wiring, and regularly check terminal crimping points for heating.
How to judge the quality of a harness?
3 methods to quickly identify harness quality: ① Visual inspection—insulation surface smooth, no burrs, bubbles, color difference, or eccentricity;
② Bending test—after 100 repeated bends, no cracks in insulation (silicone rubber) or significant whitening (PVC);
③ Burn test—quality harness self-extinguishes within ≤30 seconds after flame removal (UL VW-1/FT2 standard), while inferior harnesses continue burning with drips. Additionally, measure insulation thickness (meeting UL standards) and conductor resistance (≤UL specified maximum). Before bulk purchasing, request samples from the supplier for comprehensive quality confirmation.
Can the harness color be customized?
Any color can be customized; typically, a Pantone color number or color swatch is sufficient for color matching. Common stock colors: black, white, red, blue, yellow, green (24~48 hours shipping). Custom color MOQ depends on specifications (usually 1000 meters minimum), with delivery extended by 3~5 working days. Printing/logo service: Model numbers, LOGOs, and certification marks can be printed on the harness surface as required, supporting heat transfer and inkjet processes. Please provide a draft of the printing content before confirmation to avoid errors.
What certifications does this harness have? Can certification reports be provided?
This harness is certified by UL (USA) and CE (EU), and complies with RoHS environmental and REACH regulations. UL certification numbers are traceable, and CE declaration documents are complete. For bulk purchases, the following can be provided simultaneously: UL certification copy, material data sheet (MDS), SGS environmental test report, and product flame retardancy test report. For customers with special certification requirements (e.g., VDE, CCC, PSE, KC), please inform in advance for separate certification application arrangements.
Can the harness be processed with terminals? What terminal types are supported?
Yingna Technology offers harness terminal processing services, supporting various terminal types: pre-insulated terminals (O-type/U-type/tubular), bare terminals (OT/SC/GT), flag terminals, closed-end terminals, and spade terminals. Terminal crimping uses fully automated crimping machines, with crimp pull force meeting UL 486A standard. Customer-supplied materials (wire + terminals) or specified brands and models of terminals are acceptable. Adding heat shrink tubing or insulation sleeves after terminal crimping can further enhance insulation performance and mechanical strength.
What is the flame retardancy rating of the harness? Does it meet the UL VW-1 standard?
The flame retardant rating of this machine's wiring harness reaches UL VW-1 (Vertical Flame Test), which is the minimum flame retardant requirement of the UL 758 electronic wire standard. Higher flame retardant ratings are available: UL VW-1+ vertical flame, UL FT2 (Horizontal Flame), and UL VW-1+FT2 dual certification. Significance of flame retardant standards: In the vertical flame test, a VW-1 rated harness, after 5 applications of 15-second flames, self-extinguishes within 60 seconds, does not ignite the cotton pad below, and has no flaming drips. For applications with high fire protection requirements (e.g., inside new energy vehicle battery packs, medical equipment), it is recommended to choose a harness with a higher flame retardant rating.
What is the minimum order quantity for custom wiring harnesses? How are sampling fees calculated?
The minimum order quantity (MOQ) for standard wiring harness products is 1000 meters per specification; for simple customizations (e.g., color, printing), the MOQ can be as low as 500 meters. For first-time cooperation, samples can be arranged: sample length 1~5 meters, sampling fee 200~500 RMB (including UL certification label). The sampling fee will be refunded upon the bulk order after the sample is approved. Delivery time for bulk orders is typically 7~15 working days (depending on quantity and complexity). Rush orders can be accommodated with priority production (rush fee approx. 15%), compressing delivery time to 3~5 working days.
What is the difference between Chinese standard and American standard wiring harnesses?
The main differences between the Chinese standard (GB/T 5023) and the American standard (UL 758/AWM): ① Nominal cross-section – Chinese standard uses mm² (e.g., 0.5/0.75/1.0mm²), American standard uses AWG (e.g., 22/20/18AWG);
② Test methods – Chinese standard focuses on conductor resistance and insulation resistance, American standard focuses on mechanical properties (bending/tensile/impact);
③ Certification labels – American standard harnesses must print UL/AWM numbers, Chinese standard harnesses print CCC certification numbers;
④ Customer base – UL certification is required for export to the USA/Canada, CCC certification is required for domestic sales in China. Winna Technology's harnesses meet both Chinese and American standards, with traceable UL certification numbers.
