detailed description:
Low smoke halogen-free cable refers to a cable that does not contain halogens (F Cl、Br、I、At）、 Environmentally friendly cables made from adhesive materials that do not contain environmental substances such as lead, cadmium, chromium, mercury, etc., and do not emit toxic smoke when burned.
Reference standards: GB/T12706-2008, GB/T19666-2005 standards;
Rated voltage: 0.6/1KV;
Main technical indicators
1. The cable should withstand a power frequency voltage test of 3.5kV at ambient temperature without breakdown for 5 minutes;
2. The transmittance of the cable should meet the following requirements:
Cable outer diameter D (mm) transmittance (%) ≥ D>40705<D ≤ 105010<D ≤ 4060D ≥ 540;
3. Non flammability (flame retardant properties) of cables: They should pass the Class B bundled combustion test in GB/T19666-2005. The vertical combustion test of a single wire and cable should pass GB/T19666-2005;
4. The release amount of halogen acid gas complies with IEC754-1;
5. The pH value and conductivity of the combustion gas comply with IEC754-2, with pH ≥ 4.3 and conductivity ≤ 10 μ S/mm.
