Application of power cable

It is suitable for places with rated voltage of 450/750V and below, with halogen-free, low smoke, flame retardant requirements and high safety and environmental protection requirements. Such as high-rise buildings, stations, subways, airports, hospitals, large libraries, gymnasiums, villas, family houses, hotels, hospitals, office buildings, schools, shopping malls and other densely populated places.

Advantages of Irradiation Cross-Linked Low Smoke Halogen Free Flame Retardant Wires

The traditional PVC (polyvinyl chloride) wire, in the event of a fire, the PVC mixture is easily decomposed after being heated, and a large amount of highly toxic and corrosive HCL (hydrogen chloride) gas is released, and a large amount of highly toxic smoke is generated, causing major lives. and property damage, and bring great difficulties to rescue work (such as the South Korean subway fire). In order to avoid and reduce the secondary damage caused by fire and fire as much as possible, after more than ten years of research, it has been found that changing the outer material and process used in the product can effectively solve the problem.

The main feature of halogen-free low-smoke flame-retardant wire and cable is that all materials do not contain halogen, and the amount of smoke released during combustion is very small.

The toxicity of halogenated cables in fire is terrible. If the toxicity of the gas concentration that can cause death in 30 minutes is determined as 1, then the toxicity index of polyvinyl chloride is 15.01, and the toxicity index of halogen-free polymer is 0.79. During the fire, the strong and diffuse smoke made the victims confused, thus prolonging the time spent in the fire.

According to relevant information, when the light transmittance is 70%, the ability of human naked vision to distinguish objects is only about 5m. The light transmittance of the smoke emitted by the burning of PVC is less than 15%, that is, the naked visual distance of a person in this thick smoke is only about 2m.

Another feature of the thick smoke is that it spreads very rapidly with the hot air, and the speed can reach more than 20m/min. It can be seen that the use of halogen-free low-smoke wire and cable is essential to ensure safety. --This paragraph is quoted from Shanghai Engineering Construction DGJ08-93-2002 J10166-2002) "Code for Fire Protection Design of Wires and Cables in Civil Buildings".

To this end, the world's advanced countries have introduced halogen-free low-smoke flame retardant materials to replace the same PVC, and formulated relevant standards. Europe, the United States, and Japan have comprehensively promoted them in civilian wires. Our country has also formulated corresponding standards. For example, the country has formulated GB/T19666-2005 "General Rules for Flame Retardant and Fire Resistant Wires and Cables", and the Ministry of Public Security of the People's Republic of China has formulated GA306.1-2001 "Flame Retardant and Fire Resistant Cables: Plastic Insulation, Flame Retardant and Classification and Requirements for Fire-Resistant Cables", Ministry of Machinery Industry formulated JB/T 10491-2004 "Rated Voltage 450, 750V and Below Cross-Linked Polymer Insulated Wires and Cables", Shanghai Municipal Engineering Construction Code DGJ08-93-2002 J10166- 2002) series of standards such as "Fire Protection Design Regulations for Wires and Cables in Civil Buildings", low-smoke halogen-free flame-retardant wires have been widely used in airports, subways, large buildings, and government projects.
Adhering to the tenet of "returning the society with science and technology", we use the company's high-tech advantages to launch a new type of high-performance environmentally friendly wire through the innovation of halogen-free low-smoke flame retardant technology.

It solves the shortcomings of PVC decoration wires very well. It is halogen-free, low-smoke, flame-retardant and has excellent short-circuit load capacity. It is a wise choice for decoration.

We believe that with the improvement of people's living conditions, health, safety, More and more attention is paid to environmental protection, and the day when new high-performance environmentally friendly cloth wires will completely replace traditional PVC wires is just around the corner.
