Flame retardant grades of low-smoke and halogen-free cables
According to the test conditions specified in GB/T18380.3-2008, the flame retardant grades of low-smoke halogen-free cables are divided into four grades: A, B, C, and D. If the flame retardant grade is not indicated, it will be regarded as B grade.
Low-smoke halogen-free flame-retardant cable insulation is made of halogen-free cross-linked polyethylene, and the sheath is made of halogen-free polyolefin material, so all the materials that make up the cable are halogen-free, and the amount of smoke released when the cable is burned is very high. Less, it will not produce strong acid mist, toxic gas, and the toxicity is very small.Flame retardant grade

Single-core cable conductive core is round, 16mm2 and above can be pressed tightly. For multi-core cables with a cross-section of 35mm2 and below, the core should be round, and those with a cross-section of 50mm2 and above should be fan-shaped, tile-shaped or semicircular. The fourth core (neutral core) in a four-core cable can be round or fan-shaped. The neutral wire of a five-core cable can be round or tile-shaped. Those with a diameter of 6mm2 and below are allowed to be composed of a single conductor, and those with a diameter of 10mm2 and above are composed of multiple single wires. The shaped conductor (sector, tile or semicircle) should be tightly pressed.
