Frequently Asked Questions
What is the minimum order quantity for custom harnesses?
The MOQ for standard products is 1000pcs, but small trial orders can be as low as 100-200pcs. It is recommended to request samples for quality confirmation on the first cooperation.
What terminal types and wire gauges are supported?
Full series terminal crimping is supported (JST/Molex/TE/Hirose, etc.), with wire gauges from AWG12 to AWG32, and customizable length, color, and strip size.
What are the quality inspection standards for harnesses?
Compliance with UL 486A standards, including continuity testing, insulation withstand voltage testing, pull force testing, and visual inspection, with full inspection reports provided upon shipment.
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.
How is the wiring harness waterproofed when used outdoors?
The insulation layer of this machine's wiring harness itself is water-resistant (both silicone rubber/PVC do not absorb water), but for outdoor exposed use, it is recommended to combine the following solutions to enhance waterproofing: ① Use IP67/IP68 waterproof connectors; ② Add waterproof heat-shrink tubing (with hot melt adhesive) at the crimp; ③ Cover the cable with a PVC or PE protective sleeve to enhance mechanical protection; ④ Use potting compound (epoxy resin or polyurethane) at the connection to achieve permanent waterproofing. Combined with the above solutions, long-term underwater connection (10 meters water depth) can be achieved, suitable for scenarios such as LED underwater lights, sewage treatment equipment, and marine wiring harnesses.
What is the flame retardant rating of the wire harness? Does it comply with the UL VW-1 standard?
The flame retardant rating of this wire harness reaches UL VW-1 (vertical burn 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 burn, UL FT2 (horizontal burn), UL VW-1 + FT2 dual certification. Significance of flame retardant standards: For a wire harness that passes VW-1, in the vertical burn test, after 5 times of 15-second burning, the flame self-extinguishes within 60 seconds, does not ignite the cotton cloth below, and has no burning drips. For applications with high fire protection requirements (such as inside new energy vehicle battery packs and medical devices), it is recommended to select a wire harness with a higher flame retardant rating.
What is the insulation material of this wire harness? Does it meet environmental protection requirements?
The insulation material of this harness uses silicone rubber (Silicone Rubber) or PVC, with the corresponding material selected according to different model specifications. Silicone rubber withstands temperatures from -60℃ to 200℃; PVC withstands temperatures from -20℃ to 105℃. The entire series of wires complies with RoHS 10-item testing and REACH SVHC screening, contains no lead, mercury, cadmium, or other harmful substances, and third-party SGS test reports can be provided. Electronic wires exported to North America must meet the UL VW-1/FT2 flame retardant rating; those exported to Europe must meet the CE Low Voltage Directive.
What is the conductor material of this wire harness? Bare copper or tinned copper?
This product uses stranded tinned copper wire conductors, balancing conductivity and corrosion resistance. Bare copper conductivity is approximately 101%IACS, and tinned copper is approximately 98%IACS (difference only about 3%). Advantages of tinning: oxidation resistance is 3~5 times stronger, solderability is better (avoiding solder non-wetting issues), and corrosion resistance is significantly improved. For scenarios requiring high reliability such as new energy vehicles and outdoor equipment, it is recommended to prioritize tinned copper wire harnesses.
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 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.
How to judge the quality of wire harnesses?
3 methods to quickly identify wire harness quality: ① Visual inspection — the insulation surface is smooth with no marks, no bubbles, and no color difference or eccentricity; ② Bending test — after repeated bending 100 times, the insulation has no cracks (silicone rubber) and no obvious whitening (PVC); ③ Flame test — for high-quality wire harnesses, self-extinguishing time after removal from flame is ≤30 seconds (UL VW-1/FT2 standard); inferior wire harnesses continue burning with drippings. Also measure insulation thickness (whether it meets UL standard) and conductor resistance (≤ UL specified maximum). Before bulk purchasing, it is recommended to require the supplier to provide samples for comprehensive quality confirmation.
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.
