Common questions

What construction does this series cover?

UL PV Wire. UL 4703 photovoltaic and energy-storage DC cable. The manufacturer catalogue cites UL Recognized File No. E331816, with 600 V construction data published for the listed AWG sizes.

Can you supply cut to length?

Yes. Tell us the size, colour and quantity — or send your BOM — and we quote the length you need. No prices are published on this site; every enquiry is quoted directly.

How can I verify the certification for this series?

Ask us for the available certificate or catalogue record, or search UL Product iQ, file E331816 directly. We send the document or source record rather than relying only on a summary.

UL photovoltaic cable

Confirm the UL 4703 voltage table before design approval

UL 4703 photovoltaic wire sits under a different UL file from UL 758 AWM. Published dimensional data should be checked for the exact voltage series because the 600 V, 1000 V and 2000 V constructions are not interchangeable.

  • Confirm whether the system requires the 600 V, 1000 V or 2000 V construction series.
  • Check AWG, conductor stranding, dry and wet temperature requirements.
  • Request the current UL 4703 construction table and file scope for the selected line.

Questions & answers

Frequently asked questions

Certifications, lead time, payment, shipping and MOQ — the points buyers ask about most often. If something is still unclear, send us your requirement and we will answer directly. See the full FAQ →

01 Are you a manufacturer or a trading company?

We are a wire harness manufacturer — cutting, stripping, crimping, sealing and testing are all carried out in-house at our Suzhou plant. We are also an authorised distributor of Xinya brand electronic wire, so you can source both the wire and the finished harness from one supplier.

02 What certifications do your electronic wires have?

Our electronic wires carry UL, VDE, PSE and CE approvals, together with RoHS and REACH compliance for the European market; TUV approvals are available for PV and renewable-energy wire. Certificates and test reports are issued by the manufacturer and can be supplied with your quotation on request.

03 How long is the lead time?

For electronic wire, popular styles such as UL1007, UL1015, UL1061 and UL1569 are normally available quickly; other styles, non-standard colours and cut lengths usually take around 7 days. Wire harnesses are made to order, so the schedule depends on your drawing, connector availability and quantity — we confirm it in the quotation.

04 What are your payment terms?

We commonly accept T/T (telegraphic transfer), PayPal and Western Union. Typically a 30% deposit is required before production, with the balance paid before shipment.

05 How do you ship the goods?

Samples and small orders are shipped by international express (DHL, FedEx, UPS, TNT) or by air freight. Larger orders normally go by sea to reduce freight cost. We can quote EXW, FOB, CIF or door-to-door terms and will recommend the option that best fits your budget and delivery date.

06 Do you have a minimum order quantity (MOQ)?

We keep a low MOQ to support your business. Generally the MOQ is 1 piece for standard models, although it may vary slightly for customised products. Small trial orders are welcome.

07 Can you build harnesses to our own drawing or sample?

Yes. We build to print and build to sample — send us a 2D drawing, a BOM, connector part numbers or even a photo of the part in use, and we will assemble, test and quote accordingly.

08 Can I get a sample before placing a bulk order?

Yes. We are happy to build a prototype first so that you can approve the fit, crimp and finish before committing to volume. Send the drawing and the target quantity and we will quote sample cost and lead time.

09 What information do you need to give a quotation?

For wire: the style or UL number, AWG, voltage and temperature rating, insulation, conductor, colour and length. For harnesses: the drawing or BOM, connector brand and part number, terminal and housing type, wire specification, cut length and tolerance, sleeving or tubing, label and packaging requirements, quantity and destination. If anything is unclear we will ask — or propose a construction for you.

10 Do you support OEM / ODM and private labelling?

Yes. We work with customer-specified connectors and brands as well as JST, Molex and HongXing, and can add printed markers, custom labels, printed bags and your own carton artwork for OEM and ODM projects.

11 How do you control quality?

Every order goes through incoming wire inspection, cutting and stripping checks, crimp height and terminal pull-force testing, 100% continuity and open-and-short testing, and a final dimensional and visual inspection. Inspection records can be supplied with the shipment when your project requires them.

12 Can you help with wire and connector selection?

Yes — our engineers help match wire gauge, insulation and temperature rating to your current, voltage and working environment, and select a terminal and housing combination that crimps reliably. Describe the application or send a sample and we will propose a construction.

13 Can you supply cut lengths and custom packaging?

Yes. Wire can be supplied in cut lengths, coils or spools, with PE bags, cartons, pallets and printed labels arranged to suit your warehouse or production line.

14 Do you ship worldwide, and can I visit the factory?

We ship worldwide, with regular shipments to Europe, North America, South-East Asia, the Middle East and Australia. You are welcome to visit our plant in Suzhou, and you can see our production lines in the factory videos on this site.

15 What happens if there is a quality problem after delivery?

Contact us with the order or batch number and photos of the issue. We will check it against our production and inspection records and, where the fault is confirmed on our side, arrange replacement or credit.

Need wire to a specification?

Send the style, AWG range, colour and length — or your BOM and drawing. We will come back with construction, availability and lead time. This catalogue publishes no prices; every enquiry is quoted directly.
