Frequently Asked Questions
What is the flame retardant rating of the wiring harness? Does it comply with the UL VW-1 standard?
The flame retardant rating of this 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 optional: UL VW-1+ vertical flame, UL FT2 (horizontal flame), UL VW-1+FT2 dual certification. Significance of flame retardant standard: Wiring harnesses passing VW-1, after 5 times of 15-second burning in the vertical flame test, the flame self-extinguishes within 60 seconds, does not ignite the cotton pad below, and has no burning drips. For applications with high fire protection requirements (such as inside new energy vehicle battery packs, medical equipment), it is recommended to choose wiring harnesses with higher flame retardant ratings.
What certifications does this wiring harness have? Can certification reports be provided?
This wiring harness has passed UL (USA) and CE (EU) certifications, complying with RoHS environmental and REACH regulations. The UL certification number is traceable, and CE declaration documents are complete. When purchasing in bulk, the following can be provided simultaneously: UL certification copy, Material Declaration Sheet (MDS), SGS environmental test report, product flame retardant test report. For customers with special certification requirements (such as VDE, CCC, PSE, KC, etc.), please inform in advance, and a separate certification application can be arranged.
What is the temperature range of the wiring harness? Can it be used long-term in high-temperature environments?
The temperature range of this wiring harness varies depending on the insulation material: Silicone rubber insulation -60℃~+200℃ (short-term peak 250℃), PVC insulation -20℃~+105℃. In high-temperature environments (such as automotive engine compartments, around industrial furnaces, inside new energy vehicle battery packs), silicone rubber material wiring harnesses must be used. PVC material will accelerate aging and cause insulation cracking in such scenarios. For low-temperature environments (such as outdoor extremely cold areas) and high-low temperature cycling situations, silicone rubber wiring harnesses are also recommended.
What is the conductor material of this wiring harness? Bare copper or tinned copper?
This product uses multi-strand tinned copper wire conductors, balancing conductivity and corrosion resistance. Bare copper conductivity is approximately 101% IACS, tinned copper is approximately 98% IACS (difference is only about 3%). Advantages of tinning: Oxidation resistance is 3-5 times stronger, better solderability (avoids non-wetting issues), significantly improved corrosion resistance. For high-reliability scenarios such as new energy vehicles and outdoor equipment, it is recommended to prioritize tinned copper wire wiring harnesses.
What after-sales services are available after purchasing the wiring harness?
Winna Technology offers a standard 2-year warranty on its wire harness products. During the warranty period, non-human damage is repaired or replaced free of charge. Domestic customers enjoy a 48-hour response time and repair completion within 7 working days; overseas customers can arrange repairs via DHL/FedEx. Products beyond the warranty period are eligible for paid repair services (cost approximately 30-50% of a new product). Lifetime technical support is provided, including wire 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.
Can this wire harness be used on medical equipment? What standards must it meet?
Our standard wire harness is not recommended for direct use inside medical equipment. Medical equipment wire harnesses must comply with the IEC EN60601 standard, requiring: ① Low leakage current — standard harness leakage current ≤0.5mA, medical grade ≤0.1mA;
② Biocompatibility — insulation and terminal materials must pass ISO 10993 biocompatibility testing;
③ High isolation voltage — reinforced insulation, isolation voltage ≥4000V;
④ Cleanliness — produced in a dust-free workshop, free from ionic contamination. Winna Technology can customize medical-grade wire harnesses (including EN60601 certification), requiring advance communication of technical parameters and certification requirements, with separate production arrangements.
Can the wire harness be processed with terminals? What terminal types are supported?
Winna Technology provides wire harness terminal processing services, supporting various terminal types: pre-insulated terminals (O-type/U-type/ferrule), 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 standards. Customer-supplied materials (wire + terminals) or specified brand and model terminals are both acceptable. Adding heat shrink tubing or insulation sleeves after terminal crimping can further enhance insulation performance and mechanical strength.
How to judge the quality of a wire harness?
Three methods for quick wire harness quality assessment: ① Visual inspection — insulation surface smooth, no burrs, bubbles, color differences, or eccentricity;
② Bend test — after 100 repeated bends, no cracks in insulation (silicone rubber) and no significant whitening (PVC);
③ Burn test — high-quality harness self-extinguishes within ≤30 seconds (UL VW-1/FT2 standard), while poor-quality harness burns continuously with drips. Additionally, measure insulation thickness (meeting UL standards) and conductor resistance (≤UL specified maximum). Before bulk procurement, request samples from the supplier for comprehensive quality verification.
Will the wire harness age after long-term use? How to extend its service life?
Under normal use conditions, silicone rubber material has a service life of 10-15 years, while PVC material lasts 5-8 years. Factors affecting lifespan: ① Operating temperature — prolonged operation at the rated temperature upper limit accelerates aging (halving lifespan);
② Bending frequency — for frequent bending applications, use high-flexibility harnesses (bending life ≥10 million cycles);
③ Environmental factors — UV, ozone, and chemical solvents accelerate aging of silicone rubber outer layers. Recommendations to extend lifespan: maintain a 20% margin below operating temperature, avoid contact with chemical solvents, add protective sleeves for fixed wiring, and regularly check terminal crimping points for heating.
What are the differences between new energy vehicle wire harnesses and ordinary wire harnesses?
New energy vehicle (EV/HEV) wire harnesses must meet higher standards: ① Temperature rating — battery pack internal temperatures can reach 85-150°C, requiring silicone rubber harnesses (PVC is insufficient);
② Voltage rating — high-voltage connection harnesses withstand 600V-1000V, far exceeding the ordinary 300V;
③ EMC shielding — high-voltage harnesses require braided shielding layers 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.
What is the minimum bending radius of the wire harness? Can it be used for wiring in tight spaces?
The minimum bending radius of this wire harness is 5 times the wire diameter, much smaller than the 10 times requirement for ordinary PVC wires. Due to the multi-strand ultra-fine tinned copper wire stranding structure, the harness offers excellent flexibility, allowing flexible wiring in tight spaces such as mobile phones, sensors, car door panels, and LED fixtures, with reduced risk of core breakage even under frequent bending. For applications requiring an even smaller bending radius (e.g., robot drag chains), a high-flexibility drag chain-specific harness can be selected.
What is the minimum order quantity for custom wire harnesses? How are sample fees calculated?
The minimum order quantity (MOQ) for standard wire 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, sample fee 200-500 RMB (including UL certification label), refundable upon batch order after sample approval. Batch order lead time is typically 7-15 working days (depending on quantity and complexity). Rush orders can be scheduled for priority production (rush fee approximately 15%), with lead time compressed to 3-5 working days.
