Anhui Tianming Cable Co., Ltd. -- WDZ-KYJY33钢丝铠装电缆, Low Smoke, Halogen-Free, Flame Retardant Cable, produced in accordance with Chinese National Standards GB/T18380, GB/T19216, GB/T17651, and GB/T17650, as well as international standards.
WDZ-KYJY33 Wire Armored Cable - Low Smoke, Halogen-Free, Flame Retardant Cable; This cable is difficult to ignite and has the ability to prevent or inhibit flame spread. Moreover, once ignited, it exhibits halogen-free, low smoke, non-toxic, and non-corrosive properties. Suitable for applications such as high-rise buildings, hotels, hospitals, subways, nuclear power plants, tunnels, power plants, mines, oil, and chemical industries.

Low-smoke, halogen-free, fire-resistant cables not only meet the characteristics of low-smoke, halogen-free, flame-retardant cables but also maintain circuit power supply under fire conditions. They are mainly used in applications requiring fire resistance, such as fire alarms, firefighting equipment, smoke exhaust systems, emergency exit lighting, and other emergency power supply lines.

Two, flame-retardant rating and product performance of low-smoke halogen-free cables:
According to the test conditions specified in GB/T18380.3-2002, flame-retardant low-smoke halogen-free cables are classified into four grades: A, B, C, and D.

Wire Armored Cable WDZ-KYJY33 Low Smoke Halogen-Free Flame Retardant Cable, rated voltage 600/1000V, cross-linked polyethylene insulation, polyolefin sheath, flame retardant B class low smoke halogen-free cable, 3 cores, 240mm².
WDZB-YJY 600/1000V 3*240 Q/TEC16.05-2005

1. The rated voltage U of the control cable. / U is 450/750V.
2. The cable is designed for long-term operation at temperatures not exceeding 90°C.
3. The installation environment temperature should not be lower than 0℃.
4. Minimum Bend Radius for Cable Installation
Low-smoke zero halogen flame-retardant, fire-resistant control cables: The cable without armor layer should not be less than 6 times the cable outer diameter, and the cable with armor or copper tape shielding structure should not be less than 12 times the cable outer diameter.
B. Low-smoke zero-halogen flame-retardant, minimum bending radius for fire-resistant power cables. See the table below: (Outer diameter of D cable)

Three, Cable Structure:

Conductor: Bare copper wire or tin-plated copper wire, solid-core, multi-core braided, or fine-strand braided into bundles, conforming to GB/T 3956 and IEC 60228 *** Class (Class A), Class 2 (Class B), or Class 5 (soft structure).

Insulation: Poly (PE), Cross-linked Poly (XLPE).

Armored Sheath: Double steel strip or galvanized steel wire armor, galvanized steel wire braid armor, or copper wire braid armor (the braid density of the layer is not less than 65%).

Shielding Layer: Braided bare copper wire or tin-plated copper wire, wrapped with copper-plastic or aluminum-plastic composite tape, or a combination of braided copper wire with aluminum-plastic composite tape shielding.

Housing: Low smoke, halogen-free flame-retardant polyolefin.

Core Wire Marking: Color marking or white numbering printed on black core wire.
