Frequently Asked Questions
What is the minimum order quantity for custom wiring harnesses?

What are the quality inspection standards for wiring harnesses?
Implemented according to UL 486A standard, including continuity test, insulation withstand voltage test, pull force test, appearance inspection, providing full inspection shipment report.
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.
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.
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 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 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 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.
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.
