Frequently Asked Questions
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 depends on the insulation material: silicone rubber insulation -60°C~+200°C (short-term peak 250°C), PVC insulation -20°C~+105°C. In high-temperature environments (such as automotive engine compartments, industrial furnace surroundings, inside new energy vehicle battery packs), silicone rubber material harnesses must be used; PVC material will accelerate aging and cause insulation cracking in such scenarios. For low-temperature environments (such as outdoor polar regions) and high-low temperature cycling situations, silicone rubber harnesses are also recommended.
How to judge the quality of a wiring harness?
3 methods to quickly identify wiring harness quality: ① Visual inspection — the insulation surface is smooth without burrs, bubbles, color difference, or eccentricity;
② Bending test — after repeated bending 100 times, the insulation layer shows no cracks (silicone rubber) or obvious whitening (PVC);
③ Combustion test — high-quality harness self-extinguishes within ≤30 seconds after removing the flame (UL VW-1/FT2 standard), while inferior harnesses continue burning with dripping. Additionally, measure insulation thickness (whether it meets 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 minimum order quantity for custom harnesses? How is the sample fee calculated?
The minimum order quantity (MOQ) for standard wiring harness products is 1000 meters/specification; for simple customization (such as color or 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), and the sample fee will be refunded after the batch order is placed. Batch order delivery time is usually 7~15 working days (depending on quantity and complexity). Rush orders can be arranged for production insertion (rush fee approximately 15%), compressing delivery to 3~5 working days.
Will the wiring harness age after long-term use? How to extend its service life?
Under normal use conditions, the service life of silicone rubber material harnesses is 10~15 years, and PVC material harnesses is 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 — use high-flexibility harnesses in frequent bending scenarios (bending life ≥10 million cycles);
③ Environmental factors — UV, ozone, and chemical solvents accelerate aging of the silicone rubber outer layer. Suggestions to extend lifespan: leave a 20% margin in operating temperature, avoid contact with chemical solvents, add protective sleeves for fixed wiring, and regularly check if the terminal crimping area is heating up.
What certifications does this wiring harness have? Can certification reports be provided?
This wiring harness has UL (USA) and CE (EU) certifications, and complies with RoHS environmental and REACH regulatory requirements. The UL certification number is traceable, and CE declaration documents are complete. For bulk purchases, the following can be provided simultaneously: UL certification copy, Material Declaration Sheet (MDS), SGS environmental test report, and product flame retardancy test report. For customers with special certification requirements (such as VDE, CCC, PSE, KC, etc.), please inform in advance, and separate certification applications can be arranged.
Can the wiring harness be processed with terminals? What terminal types are supported?
Yingna Technology provides wiring 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 automatic crimping machines, with crimp pull force meeting UL 486A standards. Customer-supplied materials (wire + terminals) or specified brand and model terminals are both acceptable. After terminal crimping, adding heat shrink tubing or insulation sleeves can further improve insulation performance and mechanical strength.
Can this wiring harness be used in medical equipment? What standards must it meet?
This standard wiring harness is not recommended for direct use inside medical equipment. Medical equipment wiring harnesses must meet 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 cleanroom, free from ionic contamination. Yingna Technology can customize medical-grade harnesses (including EN60601 certification), requiring advance communication of technical parameters and certification requirements, with separate production arrangements.
What is the flame retardancy rating of the wiring harness? Does it meet the UL VW-1 standard?
The flame retardancy rating of this wiring harness reaches UL VW-1 (vertical flame test), which is the minimum flame retardancy requirement of the UL 758 electronic wire standard. Higher flame retardancy options are available: UL VW-1+vertical flame, UL FT2 (horizontal flame), UL VW-1+FT2 dual certification. Significance of the flame retardancy standard: Harnesses passing VW-1, in the vertical flame test after 5 times of 15-second burning, self-extinguish within 60 seconds, do not ignite the cotton below, and have 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 harnesses with higher flame retardancy ratings.
What is the difference between national standard wiring harnesses and American standard wiring harnesses?
Key differences between Chinese standard (GB/T 5023) and US standard (UL 758/AWM): ① Nominal cross-section – Chinese standard uses mm² (e.g., 0.5/0.75/1.0mm²), US standard uses AWG (e.g., 22/20/18AWG);
② Testing methods – Chinese standard focuses on conductor resistance and insulation resistance, US standard focuses on mechanical properties (bending/tension/impact);
③ Certification labels – US standard wire harnesses require UL/AWM numbers, Chinese standard wire harnesses require CCC certification numbers;
④ Customer base – UL certification is required for export to the US/Canada, CCC certification is required for domestic sales. Winna Technology wire harnesses comply with both Chinese and US standards, with traceable UL certification numbers.
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-induced damage within the warranty period is eligible for free repair or replacement. 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 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.
What is the insulation material of this wire harness? Does it meet environmental requirements?
The insulation material for this machine is silicone rubber or PVC, selected according to the model and specification. Silicone rubber withstands temperatures from -60°C to 200°C, while PVC withstands temperatures from -20°C to 105°C. The entire series of wires complies with RoHS 10-item testing and REACH SVHC screening, free of lead, mercury, cadmium, and other harmful substances, with third-party SGS test reports available. Electronic wires exported to North America must meet UL VW-1/FT2 flame retardant ratings, and those exported to Europe must meet the CE Low Voltage Directive.
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, far less than the 10 times requirement for ordinary PVC wires. Due to the multi-strand ultra-fine tinned copper wire stranded structure, the harness offers excellent flexibility, allowing flexible wiring in tight spaces such as mobile phones, sensors, car door panels, and LED lamps, with resistance to core breakage even under frequent bending. For applications requiring a smaller bending radius (e.g., robot drag chains), a high-flexibility drag chain-specific wire harness is available.
