In China's wire and cable industry, we have always been committed to the research and production of safe, more environmentally friendly, and more durable products. The WDZ (N) - GYJS (F)/125 wire represents. This wire fully complies with the standard of JG/T 441-2014 "Double layer co extruded insulated irradiation cross-linked halogen-free low smoke flame-retardant wires with rated voltage of 450/750 and below". Due to its excellent performance, it is widely used in various types of construction and industrial equipment.

This type of wire adopts the cable process and technology used in nuclear power plants, with a double-layer insulation structure and irradiation cross-linking process, making it excellent in mechanical and physical properties, electrical properties, and flame retardancy. At the same time, its service life has reached over 70 years, synchronized with the lifespan of buildings, truly achieving high performance and long lifespan.
Its working temperature range is wide, with long-term allowable temperatures of 90 ℃, 105 ℃, 125 ℃, and a working temperature of up to 250 ℃ during short circuits. When the ambient temperature is below 0 ℃, it is not recommended to lay cables. If construction is required in a low-temperature environment, corresponding heating measures should be taken.
When laying, attention should be paid to the bending radius of the cable. For single core cables without armor, it is 20D, and for cables with armor, it is 15D; The multi-core cable is 15D without armor and 12D with armor.
The main characteristics of WDZ (N) - GYJS (F)/125 wires are halogen-free, low smoke, flame retardant, fire-resistant, long service life, high operating temperature, and high current carrying capacity. Its advantage lies in the double-layer insulation structure design and irradiation cross-linking process, which synchronize its lifespan with the building, reaching over 70 years. When it burns, it does not release halogenated acids and other toxic and harmful gases, does not produce harmful substances such as dioxins, and does not cause secondary pollution. The cable does not contain heavy metals, making it an environmentally friendly product.
This type of wire is suitable for distribution networks or industrial installations with a rated voltage of 0.6/1kV or below. It is mainly used for fixed installation in densely populated and highly mobile buildings such as schools, hospitals, shopping malls, hotels, residential areas, transportation hubs, and public places with high safety requirements. Specially suitable for use as flame-retardant building wires.

In general, WDZ (N) - GYJS (F)/125 wire has become the representative of high-performance long-life wire and cable due to its excellent safety performance, energy saving performance, environmental protection performance, stable anti-aging performance, and long service life.
