Overview of Low Smoke Halogen-Free Cables:
Low smoke halogen-free cables are suitable for applications with a high requirement for flame retardancy, such as subways, high-rise buildings, shopping malls, theaters, power plants, chemical factories, urban squares, and other public utilities, with an AC rated voltage of 450/750V and below. The halogen-free and low smoke characteristics of these cables ensure that during a fire, the spread rate is slow, smoke concentration is low, visibility is high, and the release of harmful gases is minimal, facilitating personnel evacuation. The corrosiveness of the combustion gases is low, which also avoids damage to instruments and equipment. The low halogen and halogen-free characteristics significantly enhance the aging resistance, UV resistance, and other irradiation performance of the cable materials, thus extending the cable's service life.
Standards for Low Smoke Halogen-Free Cables:
Low smoke halogen-free cables comply with the GB9330-88 Q/WTL11-2003 standards.
Usage Characteristics of Low Smoke Halogen-Free Cables:
1. Cable rated voltage UO/U: 450/750V, AC polyolefin UO/U is 0.6/1KV.
2. The long-term working temperature of the cable is: -20℃ to 90℃, -40℃ to 105℃.
3. Recommended bending radius: unarmored cables should not be less than 6 times the outer diameter of the cable, and armored or copper tape shielded cables should not be less than 12 times the outer diameter of the cable.
Main Technical Indicators of Low Smoke Halogen-Free Cables:
1. The cable should withstand an AC voltage test of 3kV for 5 minutes without breakdown at the environmental temperature.
2. The light transmittance of the cable should meet the following table:
Cable outer diameter D (mm) Light transmittance (%) ≥ Cable outer diameter D (mm) Light transmittance (%) ≥
D > 40 705
10
3. The non-flammability (flame retardant characteristics) of the cable: should pass the B-class bundle burning test in GB12666.5-90. The vertical burning test for a single wire and cable should pass GB12666.2-90.
4. The release of halogen acid gas should comply with IEC 754-1.
5. The pH value and conductivity of the combustion gas should comply with IEC 754-2, pH ≥ 4.3, conductivity ≤ 10μS/mm.
