What are the common low-smoke halogen-free flame retardant cable materials in wire and cable?
Several common low-smoke halogen-free flame retardant cable materials
Low-smoke halogen-free cables have high-quality flame retardant properties, combustion, and no corrosive gas emissions. They are widely used in nuclear power plants, subway stations, telephone exchanges, computer control centers, high-rise buildings, large hotels, radio and television stations, important military facilities, and oil platforms. etc., a space where people are concentrated and the air density is low.
1. Plastic low-smoke halogen-free fuel
The low-smoke halogen-free flame retardant protective sleeve has a temperature resistance level of 70°C and 90°C, and the oxygen index of the general standard product reaches more than 32. It has excellent machining performance and can be widely used in power cables, communication cables, and low-smoke halogen-free cable materials. Protective jacket for control cables, marine cables.
2. Irradiation cross-linking of special low-smoke halogen-free cable materials
Irradiation cross-linked low-smoke halogen-free special cable materials are generally used in special places such as electric locomotives, oil exploration, and ships. Generally, standard cables have oil resistance and high temperature resistance. Solar photovoltaic cables not only require high temperature resistance, but also have excellent heat resistance. Nuclear power plant cables require excellent radiation resistance and thermal aging resistance.
3. Thermoplastic low-smoke halogen-free flame retardant insulating material
The performance of the low-smoke halogen-free flame retardant insulating material is similar to that of the low-smoke halogen-free protective sleeve, and the insulation performance standard is higher, and it is suitable for the insulating layer of power cables, communication cables, and electronic wires.
4. Soft low smoke halogen free flame retardant elastic material
Soft low-smoke halogen-free refers to elastic materials whose hardness standard is in the range of 75 to 85 (shoreA) (the hardness standard of ordinary halogen-free materials is about 95. With the reduction of material hardness, the physical and mechanical properties of the product, thermal deformation resistance and Flame retardant performance will be affected to a certain extent. Mainly it is more suitable for soft requirements such as elevator flat cable, large square car wire, and electronic wire with high flexibility requirements.
5. Thermoplastic low-smoke halogen-free flame retardant oxygen barrier
The inner protective sheath of the power cable adopts this material, which has high requirements on flame retardancy, which can improve the overall flame retardancy effect of the cable, and appropriately reduce the flame retardancy standard of the cable insulation sheath.
6. Low-smoke halogen-free flame retardant cable material for photovoltaic cables
Photovoltaic low-smoke halogen-free cables are a branch that has developed rapidly in recent years. At this stage, domestic products mainly meet the needs of the Rhine River with two standards, TUV and UL. Its product features are heat aging, acid and alkali resistance, water resistance, high temperature resistance, and good flame resistance.
7. Low-smoke halogen-free flame-retardant cables are used for nuclear power cables
Nuclear power is one of the development directions of new energy technology. The cables more suitable for nuclear power plants can be divided into insulation and sheath. The material used in the cable requires good radiation resistance, especially excellent heat resistance and aging resistance. In addition, nuclear power cables generally need a thermal life of 40 or 60 years. The cables have excellent flame retardancy. Cables of various specifications should be burned vertically or in bundles of Class A and Class B.
8. Oil-resistant low-smoke halogen-free flame retardant cable
At this stage, many occasions such as locomotive cables, oil platform cables, marine cables, and oil seals require materials to have high temperature resistance, oil resistance and flame resistance. The prerequisites for oil resistance mainly refer to oil resistance, diesel resistance, and heat resistance grades generally requiring 105°C to 150°C, and flame retardancy generally requires single combustion.
