| WDZN-BYJ |
| The full name of WDZN-BYJ cable is "Low Smoke, Halogen-Free, Flame Retardant and Fire-resistant Copper Core Cross-linked Polyethylene Insulated Wire", which is a high-end electrical wiring product with the triple functions of environmental protection, flame retardancy, and fire resistance. Its structure is centered on a high-purity oxygen-free copper conductor, and is sequentially covered by multiple layers of fire-resistant mica tape (providing a continuous power supply capacity of 90 minutes at temperatures ranging from 800 to 1000°C) and an irradiated cross-linked polyethylene (XLPE) insulation layer. The latter achieves molecular chain cross-linking through electron beam irradiation technology, raising the long-term working temperature to 90°C, increasing the current-carrying capacity by approximately 20% compared to traditional PVC insulated wires, and releasing smoke concentration lower than 1/3 of that of ordinary flame-retardant cables. It contains no halogens (HCL release is ≤ 5mg/g), complies with GB/T 19666 "General Principles for Flame Retardant and Fire-Resistant Wires and Cables" and GB12666.6 Fire Resistance Test Standards, and has passed CCC + S certification. This cable has a rated voltage of 450/750V and is suitable for scenarios with extremely high fire safety requirements in the AC power system, such as fire control rooms in super high-rise buildings, emergency circuits in hospitals' ICU, emergency lighting systems in subway tunnels, and core power supply lines in data centers. Its unique advantages are: 1 Fire resistance reliability: Using a double-layer mica tape winding process, it meets the Class A fire resistance requirements (maintaining power supply under a 950°C flame) as per GB/T 19216.21 standards; 2 Environmental safety: The smoke production during combustion complies with GB/T 17651.2 standards, with a light transmittance >60%, no toxic hydrogen chloride gas release, and meeting the environmental protection needs of modern green buildings; 3 Long-term performance: The XLPE insulation layer has an anti-aging life of 50 years, which is 20 years longer than that of PVC insulation, and its acid and alkali corrosion resistance is enhanced by 3 times, suitable for complex industrial environments. Compared with traditional NH-BV (fire-resistant polyvinyl chloride insulated wire), WDZN-BYJ has a 50% reduction in smoke density and a 15% increase in current-carrying capacity under the same fire resistance level. It is particularly suitable for concealed wiring in densely populated areas. Compared with ordinary WDZ-BYJ (only flame-retardant and halogen-free), its additional fire-resistant layer makes it a "double insurance" choice for power supply of fire equipment and is the core material for building an inherently safe electrical system in modern intelligent buildings. |

(1).When can I get the price?
We usually quote within 6 hours after we get your inquiry. If you are very urgent to get the price, please call us or tell us in your e-mail so that we will regard your inquiry priority.
(2).How can I get a sample to check your quality?
After price confirmation, you can require for samples to check our quality. Sample is free, but the freight charge should be paid.
(3).How long can l expect to get the sample?
After you pay the freight charge and send us confirmed files, the samples will be ready for delivery in 3-7 days. The samples will be sent to you via express and arrive in 3-5 days. You can use your own express account or prepay us if you do not have an account.
(4).What about the lead time for mass production?
Honestly, it depends on the order quantity and the season you place the order. The best record we keep is delivering 10 kilometers cable within a week. Generally speaking, we suggest that you start inquiry two months before the date you would like to get the products at your country.
