Frequently Asked Questions
Does Winna's warning light harness support non-standard interface customization?
Yes, we offer full customization services. Customers can provide drawings, samples, or interface definitions. The Winna engineering team will design molds and produce according to requirements, with flexible minimum order quantities.
How is the waterproof performance of the harness verified?
All harnesses undergo IP67-level waterproof testing (immersed in 1 meter of water for 30 minutes) before shipment, and test reports are provided. The connector part uses sealing rings and potting process to ensure long-term reliability.
What is the delivery cycle for bulk orders?
The delivery cycle for regular custom orders (1000-5000 sets) is 15-25 working days. Expedited orders can be negotiated. Winna's own factory and automated production lines can effectively shorten lead times.
Can wire harnesses be processed with terminals? Which terminal types are supported?
Yingna Technology provides wire harness terminal processing services and supports multiple terminal types: pre-insulated terminals (O-type/U-type/tube-type), bare terminals (OT/SC/GT), flag terminals, closed-end terminals, spade terminals, etc. Terminal crimping uses fully automatic crimping machines, and the crimp tensile strength complies with UL 486A. Customer-supplied materials (wire + terminals) processing or designated brand and model terminals are both acceptable. After terminal crimping, adding heat-shrink tubing or insulating sleeves can further improve insulation performance and mechanical strength.
Can this wire harness be used in medical devices? What standards must it meet?
The standard wire harness of this product is not recommended for direct use inside medical devices. Medical device wire harnesses must meet the IEC EN60601 standard, with requirements: ① low leakage current — ordinary wire 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, no ionic contamination. Yingna Technology can customize medical-grade wire harnesses (including EN60601 certification); technical parameters and certification requirements must be communicated in advance, and production will be arranged separately.
Will wire harnesses age after long-term use? How to extend service life?
Under normal operating conditions, this wire harness has a service life of 10~15 years for silicone rubber material and 5~8 years for PVC material. Factors affecting service life: ① Operating temperature — long-term operation at the upper limit of rated temperature will accelerate aging (service life halved); ② Bending frequency — for frequent bending applications, choose high-flexibility wire harnesses (bending life ≥10 million cycles); ③ Environmental factors — UV, ozone, and chemical solvents will accelerate aging of the silicone rubber outer layer. Recommendations to extend service life: leave a 20% margin in operating temperature, avoid contact with chemical solvents, install protective sleeves during fixed wiring, and regularly check whether the terminal crimp area is heating.
What certifications has this wire harness passed? Can certification reports be provided?
This wire harness has passed UL (United States) and CE (European Union) certification and complies with RoHS environmental protection and REACH regulatory requirements. The UL certification number is traceable, and CE declaration documents are complete. For bulk purchases, the following can also be provided: UL certification copy, material certificate (MDS), SGS environmental test report, and product flame retardant test report. For customers with special certification requirements (such as VDE, CCC, PSE, KC, etc.), please inform us in advance, and certification applications can be arranged separately.
What after-sales services are available after purchasing wire harnesses?
Yingna Technology wire harness products have a standard warranty of 2 years. During the warranty period, free repair or replacement is provided for damage not caused by human factors. Domestic customers receive 48-hour response and repair completion within 7 working days; overseas customers can arrange repair by DHL/FedEx. Products beyond the warranty period are provided 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 problem diagnosis. Annual framework agreement customers enjoy value-added services such as priority production scheduling, free samples, and factory inspection support.
What is the difference between new energy vehicle wire harnesses and ordinary wire harnesses?
New energy vehicle (EV/HEV) wire harnesses must meet higher standards: ① Temperature resistance grade — the internal temperature of the battery pack can reach 85~150℃, so silicone rubber wire harnesses must be selected (PVC cannot meet the requirement); ② Voltage resistance grade — high-voltage connection wire harnesses withstand 600V~1000V, far higher than ordinary 300V; ③ EMC shielding — high-voltage wire harnesses require an added braided shielding layer to prevent electromagnetic interference (EMC, compliant with CISPR 25 standard); ④ Flame retardant requirements — VW-1 + low smoke zero halogen (LSZH); ⑤ Vibration resistance — terminal crimping must not loosen under high-frequency vibration environments (vehicle operation); ⑥ TS16949 automotive quality management system certification. Ordinary wire harnesses do not meet the above requirements and are prohibited for use on new energy vehicles.
What is the minimum bending radius of the wire harness? Can it be used for wiring in confined spaces?
The minimum bending radius of this wire harness is 5 times the wire diameter, far smaller than the 10 times wire diameter requirement for ordinary PVC wire. Due to the stranded structure of multiple extra-fine tinned copper wires, the harness offers excellent flexibility and can be routed flexibly in confined spaces such as mobile phones, sensors, automotive door panels, and LED luminaires, and repeated bending is unlikely to break the core. If a smaller bending radius is required (such as robot drag chains), a high-flexibility drag-chain-specific wire harness can be selected.
What is the temperature resistance range of the wire harness? Can it be used long-term in high-temperature environments?
The temperature resistance range of the wire harnesses in this machine varies by 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, and inside new energy vehicle battery packs), silicone rubber wire harnesses must be selected; PVC material will accelerate aging and crack the insulation layer in such scenarios. For low-temperature environments (such as extremely cold outdoor areas) and high-low temperature cycling applications, silicone rubber wire harnesses are also recommended.
What is the difference between GB standard wire harnesses and US standard wire harnesses?
The main differences between GB standard (GB/T 5023) and US standard (UL 758/AWM): ① Nominal cross-section — GB uses mm² (such as 0.5/0.75/1.0mm²), while US standard uses AWG (such as 22/20/18AWG); ② Test methods — GB focuses on conductor resistance and insulation resistance, while US standard focuses on mechanical properties (bending/tensile/impact); ③ Certification markings — US standard wire harnesses must be printed with UL/AWM number, while GB standard wire harnesses are printed with CCC certification number; ④ Customer groups — export to the US/Canada requires UL certification, and domestic sales require CCC certification. Yingna Technology wire harnesses meet both GB and US standards, and UL certification numbers are traceable.
