Frequently Asked Questions
What is the minimum order quantity for custom harnesses?
The MOQ for standard products is 1000pcs, small trial orders can be as low as 100-200pcs. It is recommended to request samples for quality confirmation for the first cooperation.
What terminal types and wire gauges are supported?
Supports full series terminal crimping (JST/Molex/TE/Hirose, etc.), wire gauge from AWG12 to AWG32, customizable length, color, and strip size.
What are the quality inspection standards for wire harnesses?
Implemented according to UL 486A standard, including continuity test, insulation withstand voltage test, pull force test, visual inspection, and provides full inspection shipping report.
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.
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 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.
Can the color of the wire harness be customized?
Any color can be customized; usually provide a Pantone color number or color swatch for color matching. Common stock colors: black, white, red, blue, yellow, green (shipped within 24~48 hours). Custom color MOQ depends on specifications (usually from 1000 meters), lead time extended by 3~5 working days. Printing/marking service: model, LOGO, certification mark, etc. can be printed on the wire harness surface as required; both heat transfer printing and inkjet coding processes are supported. Please provide a printing draft before confirming the printing content to avoid errors.
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.
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.
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 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.
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.
