What WDZN-RYJS DOES :
During a fire, this cable will:
Continue conducting electricity for 90+ minutes (IEC 60331)
Emit NO toxic halogen gases – safe for people (IEC 60754)
Produce LOW smoke – evacuation visibility (IEC 61034)
Self-extinguish – prevent fire spread (IEC 60332-1)
Carry higher current – 90°C XLPE rating
Length per roll: 100 meters
Automated production, precision testing, and strict QC ensure every product meets standards for reliable quality and delivery.
You should consider the application (indoor/outdoor), voltage rating, current load, environmental conditions (temperature, moisture, chemicals), and local safety standards (like IEC or GB). If unsure, share your project details with us, and we’ll recommend the best solution.
Our cables are manufactured to meet major international standards including IEC, and comply with Chinese national standards (GB). Certifications are available upon request.
Yes. We offer full customization on cable length, conductor size, insulation material, jacket color, and packaging to meet your specific project or branding needs.
MOQ varies by product type. For standard cables, we have low MOQs; for custom orders, MOQs are flexible. Contact us with your requirements for details.
Standard orders usually take 7–15 working days. Custom orders take 15–30 working days, depending on specifications and quantity. Delivery time also depends on your location and shipping method.
We accept T/T (Telegraphic Transfer), L/C (Letter of Credit), and other terms by negotiation. Our standard terms are 30% deposit, 70% balance before shipment.
Every batch of cables goes through strict quality control, including raw material inspection, production process checks, and final performance testing (electrical, mechanical, and environmental tests). We can provide test reports for your order.
Yes, we provide free small samples for quality testing (you only cover the shipping cost). Bulk order samples can also be arranged based on your requirements.
Our cables come with a standard warranty against manufacturing defects. The warranty period varies by product type, usually 1–3 years under normal use conditions.
