Frequently Asked Questions
What certifications does this harness have? Can certification reports be provided?
This harness has UL (USA) and CE (EU) certifications, complies with RoHS environmental and REACH regulatory requirements. The UL certification number is traceable, and CE declaration documents are complete. For bulk purchases, we can simultaneously provide: UL certification copy, Material Declaration Sheet (MDS), SGS environmental test report, and product flame retardant test report. For customers with special certification requirements (e.g., VDE, CCC, PSE, KC), please inform us in advance so that separate certification applications can be arranged.
What is the temperature range of the harness? Can it be used long-term in high-temperature environments?
The temperature range of this harness depends on the insulation material: Silicone rubber insulation: -60℃~+200℃ (short-term peak 250℃); PVC insulation: -20℃~+105℃. In high-temperature environments (e.g., automotive engine compartments, industrial furnace surroundings, inside new energy vehicle battery packs), silicone rubber material harnesses must be used. PVC material in such scenarios will accelerate aging and cause insulation cracking. For low-temperature environments (e.g., extreme outdoor cold regions) or high-low temperature cycling situations, silicone rubber harnesses are also recommended.
How to judge the quality of a harness?
3 methods to quickly identify harness quality: ① Visual inspection – The insulation surface should be smooth without burrs, bubbles, color differences, or eccentricity;
② Bend test – After 100 repeated bends, the insulation should have no cracks (silicone rubber) or significant whitening (PVC);
③ Burn test – High-quality harnesses self-extinguish within ≤30 seconds after removing the flame source (UL VW-1/FT2 standard), while inferior harnesses continue to burn and have dripping. Additionally, measure insulation thickness (meeting UL standards) and conductor resistance (≤UL specified maximum). Before bulk purchasing, it is recommended to request samples from the supplier for comprehensive quality confirmation.
What is the flame retardant grade of the harness? Does it meet the UL VW-1 standard?
The flame retardant grade of this harness reaches UL VW-1 (vertical flame test), which is the minimum flame retardancy requirement of the UL 758 electronic wire standard. Higher flame retardant grades are optional: UL VW-1 + vertical flame, UL FT2 (horizontal flame), UL VW-1 + FT2 dual certification. Significance of flame retardant standards: Harnesses passing VW-1, in a vertical flame test with 5 applications of 15-second flames, will self-extinguish within 60 seconds, not ignite the cotton pad below, and have no burning drips. For applications with high fire protection requirements (e.g., inside new energy vehicle battery packs, medical equipment), it is recommended to choose harnesses with higher flame retardant grades.
Can the color of the harness be customized?
Any color can be customized; usually, providing a Pantone color number or color swatch is sufficient for color matching. Common stock colors: Black, white, red, blue, yellow, green (24-48 hour shipping). Custom color MOQ depends on the specification (usually 1000 meters minimum), with delivery extended by 3-5 working days. Printing/marking service: Model numbers, LOGOs, certification marks, etc., can be printed on the harness surface as required, supporting both thermal transfer and inkjet printing processes. Please provide a draft of the printing content before confirmation to avoid errors.
What is the conductor material of this harness? Bare copper or tinned copper?
This product uses a multi-strand tinned copper wire conductor, balancing conductivity and corrosion resistance. Bare copper conductivity is approximately 101% IACS, while tinned copper is approximately 98% IACS (a difference of only about 3%). Advantages of tinning: Oxidation resistance is 3-5 times stronger, solderability is better (avoiding non-wetting issues), and corrosion resistance is significantly improved. For high-reliability scenarios such as new energy vehicles and outdoor equipment, it is recommended to prioritize tinned copper wire harnesses.
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, much smaller than the 10 times wire diameter requirement for ordinary PVC wires. Due to the 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 lights, with low risk of core breakage even with 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.
Will the harness age after long-term use? How to extend its service life?
Under normal usage conditions, the service life of this harness is 10-15 years for silicone rubber material and 5-8 years for PVC material. Factors affecting lifespan: ① Operating temperature – Long-term operation at the rated temperature upper limit will accelerate aging (halving the lifespan);
② Bending frequency – For frequent bending applications, choose high-flexibility harnesses (bending life ≥10 million cycles);
③ Environmental factors – UV rays, ozone, and chemical solvents will accelerate the aging of the silicone rubber outer layer. Suggestions for extending lifespan: Leave a 20% margin in operating temperature, avoid contact with chemical solvents, add protective sleeves for fixed wiring, and periodically check the terminal crimping points for heat generation.
Can terminals be processed on the harness? What types of terminals are supported?
Winna Technology provides wire 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, spade terminals, etc. Terminal crimping is performed using fully automatic crimping machines, with crimp pull force meeting UL 486A standards. Processing of customer-supplied materials (wire + terminals) or designated brand and model terminals is available. After terminal crimping, applying heat shrink tubing or insulating sleeves can further enhance insulation performance and mechanical strength.
Can this wire harness be used in medical equipment? What standards must it meet?
This machine's 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 wire harness leakage current ≤0.5mA, medical-grade ≤0.1mA;
② Biocompatibility—insulation layer and terminal materials must pass ISO 10993 biocompatibility testing;
③ High isolation voltage—reinforced insulation, isolation voltage ≥4000V;
④ Cleanliness—manufactured in a dust-free workshop with no ionic contamination. Winna Technology can customize medical-grade wire harnesses (including EN60601 certification), requiring prior communication of technical parameters and certification requirements, with separate production arrangements.
What after-sales services are available after purchasing the wire harness?
Winna Technology wire 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 time and repair completion within 7 working days; overseas customers can arrange repair via DHL/FedEx. Products beyond the warranty period are eligible for paid repair services (cost approximately 30~50% of new product price). 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.
What is the minimum order quantity for customized wire harnesses? How is the sample fee calculated?
The minimum order quantity (MOQ) for standard wire harness products is 1000 meters per specification; for simple customization (e.g., color, printing), the MOQ can be as low as 500 meters. For first-time cooperation, sampling can be arranged: sample length 1~5 meters, sample fee 200~500 RMB (including UL certification label). The sample fee is refunded upon batch order placement after sample approval. Batch order delivery typically takes 7~15 working days (depending on quantity and complexity). Rush orders can be accommodated with priority production scheduling (rush fee approximately 15%), compressing delivery to 3~5 working days.
