With the development of the power cable industry, there are many types of products
produced.
LSZH cables are one of them
.
The product has superior flame retardant performance, little smoke during combustion, no corrosive gas escape, widely used in nuclear power plants, subway stations, telephone exchanges and computer control centers, high-rise buildings, hotels, radio and television stations, important military facilities, oil platforms, etc.
, as well as places with concentrated personnel and low air density
.
Halogen-free (F, Cl, Br, I, At) and lead, cadmium, chromium, mercury and other environmental substances are made of rubber materials, because it does not emit toxic smoke (such as: hydrogen halide, carbon monoxide, carbon dioxide, etc.
) when burned, so it is also called an environmentally friendly cable
.
1 where the halogen pointer is: all halogen values≦ 50PPM (according to PREN 14582)
2 The content of hydrogen halide gas produced after combustion< 100PPM (according to the regulation EN5067-2-1)
3 PH value of hydrogen halide gas dissolved in water after combustion≧4.
3 (weakly acidic) (according to the regulation EN-50267-2-2)
4 The light transmittance of the product is ≧60% after burning in a closed container through a beam of light (according to the regulation EN-50268-2)
5 Pb<90PPM, Cd, Cr6+, Hg, PBBs, PBDEs are less than 5PPM
Use:
[1] The wire and cable products have superior flame retardant performance, little smoke during combustion, no corrosive gas escape, and are widely used in nuclear power plants, subway stations, telephone exchanges and computer control centers, high-rise buildings, hotels, radio and television stations, important military facilities, oil platforms, etc.
, as well as places with high personnel concentration and low air density
.
(1) The tensile strength is greater than that of general PVC wires: the tensile strength of general PVC wires is greater than 1.
05Kgf/mm2, while the tensile strength of LSZH wires is greater than 1.
2Kgf/mm2;
(2) Good weather resistance (-30°C~105°C);
(3) Good softness (hardness of 80-90);
(4) Non-transferable (because plasticizers are not added to the formulation of this product, there will be no transferability);
(5) No toxic black smoke will be produced when burning (a small amount of white smoke will be produced);
(6) It has high volume resistivity: PVC wire is generally 1012~1015Ω/cm3, and LSZH wire is greater than 1016Ω/cm3;
(7) It has good high-voltage resistance characteristics: PVC wire is generally resistant to more than 10KV, while low-smoke halogen-free wire is as high as 15KV or more;
(8) It has good elasticity and viscosity
.
3.
LSZH wire formula addition materials:
(1) Linear PE and elastic PE are selected as the main resins, and three kinds of metal oxides containing crystal water are selected for flame retardant materials: loss of crystal water
above 200 °C, 300 °C and 300 °C respectively.
Environmentally friendly wire and cable has the following advantages:
1, high flame retardancy:
Green fully ensures that the building requires fire protection from the cables, cables that do not burn easily on fire, and can prevent the spread of flames, in the expansion of burning and disasters
.
2, halogen-free:
Green insulation, sheath and special oxygen barrier materials not only have good electrical properties, mechanical properties, and ensure that the product does not contain halogens, solve the formation of secondary pollution during combustion, avoid traditional PVC wires and combustion to produce carcinogenic dioxins" materials
.
3, low toxin:
Lead, cadmium and other harmful heavy metals, do not use cables and dispose of soil, water pollution insulation and sheath.
Toxicity tests are required, and rats are provided for safe and sound under experimental conditions
.
4, no corrosive gas:
Hydrochloric acid and other toxic gases, environmentally friendly wire and cable environment pollution-free production of new special coating materials environmentally friendly wire and cable materials, during use and combustion will not produce very little emission of acid gas, personnel and equipment, instrument damage and more environmentally friendly characteristics
.
5, High light transmittance:
The smoke produced by cable burning is very thin, evacuation and fire extinguishing work
.
The light transmittance of the product is greater than 40%, which is much higher than the standard of light transmittance of traditional flame retardant cables below 20
%.
6, waterproof, anti-ultraviolet:
Environmentally friendly wire and cable special molecular structure to ensure ultra-low water absorption green environmental protection materials
.
Special UV absorber makes the product have good UV
protection.
To ensure the safe use of these products, the service life
is extended.
The first launch of the name "Green Line" is a Japanese company, product standard FN (environmental material) environmentally friendly cable standard, Western countries, the United Kingdom also developed advanced environmental protection cable requirements standards, and later gradually spread to the development world
.
The "green line" that is now called is actually produced
according to the cable standards of Japan Cable FN.
It should be noted that LSZH cables forcibly stopped saying that they were "green lines"
