I. Product Introduction
This flame-retardant, Class B1, low-smoke, halogen-free cable utilizes a high-resistance, compact construction process. The insulation layer uses cross-linked polyethylene to enhance the cable's electrical performance. The armored cable features an oxygen barrier, significantly improving its flame retardancy and fire resistance. The sheath is constructed from low-smoke, halogen-free, high-resistance, environmentally friendly polyolefin, further enhancing the cable's flame retardancy, fire resistance, and mechanical properties.
In the event of a fire, this cable effectively prevents the spread of fire. It burns without releasing toxic halogen gases and significantly reduces smoke emissions. This is extremely beneficial for fire rescue operations, effectively minimizing casualties and property losses.
Scope of Application:
It is suitable for distribution networks or industrial installations with rated voltages of 0.6/1kV and below in industrial and residential buildings. It is particularly well-suited for fire protection systems in construction projects, such as subways, airports, train stations, shopping malls, hotels, schools, hospitals, convention centers, data centers, transportation hubs, high-rise buildings, and other densely populated areas and locations requiring special protection.
Implementation Standard:
GB 31247-2014
GB/T 12706.1-2020

III. Product Characteristics
Excellent Performance:
This flame-retardant, Class B1, low-smoke, halogen-free cable offers excellent flame retardancy, fire resistance, low smoke levels, and low toxicity.
It overcomes the drawbacks of traditional halogen-containing polymers, which produce large amounts of smoke and corrosive gases when burned.
Applications:
Particularly suitable for use as flame-retardant building cables.
Compliant Standards:
The flame retardant performance of WDZB1-YJY, WDZB1-YJY23, WDZB1N-YJY, and WDZB1N-YJY23 cables meets the requirements of GB/T 31248-2014, "Test Method for Flame Propagation, Heat Release, and Smoke Generation Characteristics of Electrical or Optical Fiber Cables Subjected to Fire," including tests for charring height, heat release, and smoke generation.
