The Advantages of Low-smoke Halogen-free Cables over Ordinary Power Cables

1. What is the use of low-smoke halogen-free cables?

Low-smoke halogen-free flame-retardant wires and cables have excellent flame-retardant functions, with less smoke during combustion and no corrosive gas escape. It is widely used in nuclear power plants, subway stations, telephone exchanges and computer control centers, high-rise buildings, hotels, broadcasting and television stations, important military facilities and oil channels, etc., as well as places with relatively concentrated personnel and low air density.

2. Features of low-smoke halogen-free cables:

(1) The tensile strength is higher than that of general PVC cable: the tensile strength of general PVC wire is greater than 1.05Kgf/mm2, and the tensile strength of low-smoke halogen-free cable is greater than 1.2Kgf/mm2;

(2) Outstanding weather resistance (-30℃~105℃);

(3) Outstanding softness (hardness 80-90);

(4) Not removable (because no plasticizer is added to the product formula, there will be no shape change);

(5) No toxic black smoke will occur during combustion (a small amount of white smoke will occur);

(6) High volume resistivity: PVC wire is generally 1012~1015Ω/cm3, and low-smoke halogen-free cable is greater than 1016Ω/cm3;

(7) Excellent high-voltage characteristics: PVC wires are generally greater than 10KV, and low-smoke and halogen-free wires are as high as 15KV;

(8) Excellent elasticity and viscosity.
