Low-smoke halogen-free cables for overhead insulated conductors refer to environmentally friendly materials that do not contain halogens (F, Cl, Br, I, At) and lead, cadmium, chromium, mercury and other environmental substances. Type cable.
1. Cable extra voltage UO / U: 450 / 750V, AC polyolefin UO / U is 0.6 / 1KV
2.Temporary task temperature of the cable: -20 ℃ －90 ℃, -40 ℃ －105 ℃
3. Recommended bending radius: unarmored cables should be no less than 6 times the outer diameter of the cable, and cables with armor or copper tape shielding should be no less than 12 times the outer diameter of the cable.
This product is suitable for places with high requirements for cable flame retardant properties, such as subways, high-rise construction, shopping malls, theaters, power stations, chemical factories, city squares and other public utilities with AC and extra voltages of 450 / 750V and below. The halogen-free, low-smoke, low-halogen and low-smoke characteristics of the cable, when the fire breaks out, the spreading speed is slow, the smoke concentration is low, the visibility is high, and the amount of harmless gas release is small, which is convenient for personnel to evacuate. The extinguishing gas is less corrosive, and also prevents damage to the equipment. The low halogen and halogen-free characteristics make the cable materials greatly improved in aging resistance, ultraviolet resistance and other radiation functions, thereby extending the service life of the cable.
(1) Tensile strength is greater than ordinary PVC wires: ordinary PVC wires have a tensile strength greater than 1.05Kgf / mm2, and low-smoke halogen-free wires have a tensile strength greater than 1.2Kgf / mm2;
(2) Good weather resistance (-30 ℃ ~ 105 ℃);
(3) Has good softness (hardness is 80-90);
(4) non-moving (because it is not necessary to add plasticizers in this product formula, there will be no shape-shifting);
(5) No toxic black smoke will occur when it is extinguished (a large amount of white smoke will occur);
(6) Has a high volume resistivity: PVC wires are generally 1012 ~ 1015Ω / cm3, and low-smoke halogen-free wires are greater than 1016Ω / cm3;
(7) Good high voltage resistance: PVC wires are generally resistant to more than 10KV, and low-smoke halogen-free wires are more than 15KV;
(8) It has good elasticity and viscosity.
This product has excellent flame retardancy, little smoke when extinguished, and no corrosive gas escapes. It is widely used in nuclear power stations, subway stations, telephone exchanges and computer control centers, high-rise buildings, hotels, broadcast television stations, important military equipment, Oil platforms, etc., as well as places with concentrated personnel and low air density.
