Frequently Asked Questions
What is the minimum order quantity for custom harnesses? How are sampling fees calculated?
The standard minimum order quantity (MOQ) for regular harness products is 1000 meters per specification; for simple customization (such as color or printing), the MOQ can be as low as 500 meters. For initial cooperation, samples can be arranged: sample length 1~5 meters, sampling fee 200~500 RMB (including UL certification label), and the sampling fee will be refunded after the sample is approved for batch orders. Delivery time for batch orders is typically 7~15 working days (depending on quantity and complexity). Rush orders can be arranged for expedited production (expediting fee approximately 15%), with delivery time compressed to 3~5 working days.
Can terminals be processed on the harness? What terminal types are supported?
Yingna Technology provides 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, spade terminals, etc. Terminal crimping uses fully automated crimping machines, with crimp pull force meeting UL 486A standards. Processing of customer-supplied materials (wire + terminals) or specified brand and model terminals is acceptable. Adding heat shrink tubing or insulating sleeves after terminal crimping can further enhance insulation performance and mechanical strength.
What after-sales services are provided after purchasing the harness?
Yingna Technology harness products come with a standard 2-year warranty. Non-human 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 new product price). Lifetime technical support is provided, including harness selection consultation, terminal processing solutions, and quality issue diagnosis. Customers with annual framework agreements enjoy value-added services such as priority production scheduling, free samples, and factory inspection support.
What is the minimum bending radius of the harness? Can it be used for wiring in tight spaces?
The minimum bending radius of this harness is 5 times the wire diameter, much smaller than the 10 times wire diameter requirement for ordinary PVC wires. Due to the use of a multi-strand ultra-fine tinned copper wire stranded structure, the harness has excellent flexibility and can be flexibly routed in tight spaces such as mobile phones, sensors, car door panels, and LED lamps, and is not prone to core breakage even with frequent bending. For applications requiring an even smaller bending radius (such as robot drag chains), high-flexibility drag chain-specific harnesses can be selected.
Will the harness age after long-term use? How can its service life be extended?
Under normal use conditions, the service life of silicone rubber material is 10~15 years, and PVC material is 5~8 years. Factors affecting lifespan: ① Operating temperature – long-term operation at the rated temperature limit will accelerate aging (halving lifespan);
② Bending frequency – for frequent bending applications, choose high-flexibility harnesses (bending life ≥10 million cycles);
③ Environmental factors – UV, ozone, and chemical solvents can accelerate aging of the silicone rubber outer layer. Suggestions for extending lifespan: maintain a 20% margin below the operating temperature limit, avoid contact with chemical solvents, install protective sleeves for fixed wiring, and regularly check terminal crimping points for heat generation.
How to judge the quality of a harness?
Three methods for quickly identifying harness quality: ① Visual inspection – the insulation surface should be smooth without burrs, bubbles, color differences, or eccentricity;
② Bending test – after 100 repeated bends, the insulation layer should show no cracks (silicone rubber) or significant whitening (PVC);
③ Burn test – a quality harness should self-extinguish within ≤30 seconds after the flame source is removed (UL VW-1/FT2 standard), while inferior harnesses will continue to burn and have dripping material. Additionally, insulation thickness (whether it meets UL standards) and conductor resistance (≤UL specified maximum) can be measured. Before bulk purchasing, it is recommended to request samples from the supplier for comprehensive quality confirmation.
What is the flame retardant rating of the harness? Does it comply with the UL VW-1 standard?
The flame retardant rating of this harness reaches UL VW-1 (vertical flame 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 flame, UL FT2 (horizontal flame), UL VW-1+FT2 dual certification. Meaning of flame retardant standard: A harness passing VW-1, in a vertical flame test, after 5 applications of 15-second flame, the flame will self-extinguish within 60 seconds, will not ignite the cotton pad below, and will 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 retardant ratings.
What is the conductor material of this harness? Bare copper or tinned copper?
This model uses a multi-strand tinned copper wire conductor, balancing conductivity and corrosion resistance. Bare copper conductivity is approximately 101% IACS, while tinned copper is approximately 98% IACS (difference of only about 3%). Advantages of tinning: 3~5 times stronger oxidation resistance, better solderability (avoiding poor soldering issues), and significantly improved corrosion resistance. For high-reliability applications such as new energy vehicles and outdoor equipment, it is recommended to prioritize tinned copper wire harnesses.
What is the temperature range of the harness? Can it be used for long periods in high-temperature environments?
The temperature resistance range of this machine's wiring harness 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, industrial furnace surroundings, and inside new energy vehicle battery packs), silicone rubber wiring harnesses must be used. PVC material will accelerate aging and cause insulation cracking in such scenarios. For low-temperature environments (such as outdoor extreme cold regions) and high-low temperature cycling conditions, silicone rubber wiring harnesses are also recommended.
Can the color of the wiring harness be customized?
Any color can be customized. Typically, providing a Pantone color number or color swatch is sufficient for color matching. Common stock colors: Black, White, Red, Blue, Yellow, Green (24~48 hours delivery). The MOQ for custom colors depends on specifications (usually 1000 meters minimum), with delivery extended by 3~5 working days. Printing/logo marking service: Model numbers, LOGOs, certification marks, etc., can be printed on the harness surface as required, supporting both thermal transfer and inkjet processes. Please provide a draft of the printed content before confirmation to avoid errors.
What certifications does this wiring harness have? Can certification reports be provided?
This machine's wiring harness is certified with UL (USA) and CE (EU), 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 Data Sheet (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 in advance, and separate certification applications can be arranged.
What is the insulation material of this wiring harness? Does it meet environmental requirements?
This machine's insulation material uses silicone rubber or PVC, selected according to the model and specifications. Silicone rubber withstands -60℃~200℃, PVC withstands -20℃~105℃. The entire series of wires complies with RoHS 10-item testing and REACH SVHC screening, free of harmful substances such as lead, mercury, and cadmium, and a third-party SGS test report can be provided. 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.
