Low Smoke Halogen-Free Cable
Product Details
- Low smoke halogen-free cable flame retardant performance is superior, combustion smoke is very little, no corrosive gas escape.
- It is widely used in nuclear power plants, subway stations, telephone switches and computer control centers, high-rise buildings, hotels, radio and television stations, important military facilities, oil platforms, as well as places with relatively concentrated personnel and low air density.
Insulation Requirements of Low-smoke Halogen-free Cables:
(1)Low-smoke Halogen-free Fuel
The temperature resistance grade of low-smoke halogen-free cable flame retardant sheath has 70℃, 90℃, generally requires the product oxygen index of more than 32, has good mechanical performance and processing performance, can be widely used in power cable, communication cable, control cable, Marine cable and another sheath layer.
(2)Low-smoke Halogen-free Cable Flame Retardant Insulating Material
The properties of low-smoke halogen-free flame-retardant insulating materials are similar to those of low-smoke halogen-free sheathing materials, and the insulation performance requirements are higher. It can be used for the insulating layer of power cables, communication cables, and electronic wires.
(3)Low-smoke Halogen-free Flame Retardant Cable Flame Retardant Oxygen Barrier
The material is used for the inner sheath layer of power cables with high flame retardant requirements, which can improve the overall flame retardant effect of the cable and appropriately reduce the flame retardant requirements for the cable insulation sheath layer.
Low Smoke Halogen-Free Cable
Product Details
- The low-smoke halogen-free organic flame retardant is added to the silane cross-linked polyethylene insulating material, which is much better than the traditional inorganic flame retardant.
- It has excellent electrical properties and anti-aging properties, long service life, and excellent flame retardant properties.
- It can reach the low-smoke halogen-free level, which is safer and more environmentally friendly.
The cable structure is as follows:
① Rare earth high iron aluminum alloy conductor material;
②Refractory mica tape;
③Low-smoke halogen-free flame retardant silane cross-linked polyethylene insulation;
④Flame-retardant glass fiber wrapping tape;
⑤Aluminum alloy belt interlocking armor;
⑥ Polyolefin sheath.
Power frequency rated voltage Uo/U: 0.6/1kV.
The allowable long-term working high temperature of the cable conductor: 90℃.
Product Standards
This product is produced according to GB12706 “Rated Voltage 1kV~35kV Extruded Insulated Power Cables and Accessories” standard, and can also be produced according to the requirements of users according to the recommended standards of the International Electrotechnical Commission IEC, British standards, German standards and American standards.
Scope of Application
This product is suitable for fixed installation in distribution networks or industrial installations with power frequency rated voltage of 0.6/1kV and below.
Use Features
Power frequency rated voltage Uo/U: 0.6/1kV.
The allowable higher temperature of the cable conductor during short circuit (longer duration does not exceed 5s): 250℃.
The ambient temperature should not be lower than 0°C during cable laying.
The bending diameter of the multi-core cable is not less than 15 times the outer diameter of the cable, and the bending diameter of the single-core cable is not less than 20 times the outer diameter of the cable.
Low-smoke halogen-free cables have excellent flame retardant properties, little smoke when burning, and no corrosive gas escapes. They 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 a high concentration of people and low air density.
Differences in The LSZH Cable
In contrast to PVC sheath, LSZH cables use sheath materials made of thermoplastic materials that produce no halogens or caustic acids, produce little or no smoke, and significantly reduce flame spread, all of which allow people are able to escape from fire areas more easily, reducing hazardous work for firefighters.
LSZH compounds are usually based on polyolefins and incorporate hydrated minerals, resulting in only less intense white fumes.
Over the years since the LSZH cable was introduced, other compound materials have been referenced, with better results, while maintaining the electrical properties necessary for the cable.
Polymer materials that are not inherently flame retardant incorporate additives such as inorganic hydrates (aluminum or magnesium hydroxide) to optimize flame retardant properties.
Such heavy doping often degrades some physical properties, so the cable industry has developed various methods using different compounds to reduce or eliminate their effects.
