WDZN-YJVR22 Low Smoke Zero Halogen Flame Retardant Cable 3x240+1x95 is **a type of cable**, which means:

* WDZN: This is a composite symbol representing low smoke, halogen-free, flame-retardant, and fire-resistant. WD indicates flexibility, ZN signifies fire resistance, W stands for halogen-free, and Z for flame-retardant.
YJVR22: This is a cross-linked polyethylene insulated, sheathed copper wire braided double-core flame-retardant cable.
3x240+1x95: Indicates 3 wires of 240 square millimeters and 1 wire of 95 square millimeters.

Low-smoke, halogen-free materials refer to the insulation of this cable being made from such material. This material emits less toxic gases when burned, does not produce thick smoke, and does not emit black smoke containing halogen impurities upon combustion. Halogen-free means that no halogen-containing substances are present during the material manufacturing process, and no harmful gases are produced upon combustion.

Therefore, for cables requiring high comprehensive properties such as flame-retardant, low-smoke, and halogen-free, the WDZN-YJVR22 low-smoke halogen-free flame-retardant flame-retardant cable 3x240+1x95 is a suitable choice. The WDZN-YJVR22 low-smoke halogen-free flame-retardant flame-retardant cable 3x240+1x95 is a **flame-retardant cable** with characteristics of flame-retardant, low-smoke, low-halogen, non-toxic, and flame-retardant. It is suitable for rated voltage 330V, with a long-term operating temperature of 90 degrees Celsius and a short-term operating temperature of 130 degrees Celsius. The cable model consists of three parts: WDZN: halogen-free low-smoke flame-retardant flame-retardant, which is the cable's characteristic code; YJVR22: cross-linked polyethylene insulated polyethylene sheath copper wire braid flame-retardant cable; 3x240+1x95: indicates the number of cores and cross-sectional area of the cable, where 240 represents the cross-sectional area of the wire is 240 square millimeters, and 95 represents the cross-sectional area of the cable wire is 95 square millimeters. **Flame-retardant cable - WDZN-YJVR22 low-smoke halogen-free flame-retardant flame-retardant cable 3x240+1x95 is a model for two cables, namely 3x240+1x95 copper-core flame-retardant low-smoke halogen-free polyolefin insulated wire and 2x240+1x95 copper-core flame-retardant low-smoke halogen-free polyolefin insulated cable**.
The former has a rated voltage of 750V or above, while the latter depends on the flame-retardant, halogen-free, low-smoke rating, such as the cable ZA-WDZN-YJVR22, which is part of the flame-retardant, low-smoke, halogen-free, fire-resistant cable series. Due to its flame-retardant rating of ZA, it does not release toxic gases when burning at a smoke temperature of 750℃^[1]^.

Fire-resistant cable functions: Under fire conditions, it can operate normally, providing power supply for firefighting, communication, and lighting during fires, effectively evacuating people, and creating favorable conditions for extinguishing the fire. Low-smoke, halogen-free flame-retardant cables produce less smoke concentration when the cable catches fire, posing less harm to humans; they have excellent flame-retardant properties, can foam and expand upon contact with fire, offering good heat and fire insulation, and can also prevent the spread of flames [2].

WDZN-YJVR22 Low Smoke Halogen-Free Flame Retardant Fire Resistant Cable 3x240+1x95 is a **power cable** that features low smoke, low halogen, flame retardant properties, and meets fire resistance requirements, suitable for indoor installation and use.
