Fire accidents caused casualties, the real murder is actually ordinary BV, BVR wire!
With the development of social economy, the demand for electricity for enterprises and households has increased year by year, and the probability of electrical fires has risen sharply, which seriously threatens the lives and property of the people. Among them, the cause of electrical fires, whether it is leakage, short circuit, overload, or excessive contact resistance, is often related to the performance of the wire insulation layer. When a fire breaks out, the burning wires become the main cause of casualties.
Ordinary BV, BVR wire insulation layer becomes hard, cracked, and even damaged after aging, and the temperature resistance and heat resistance are reduced. Once the current carrying capacity is increased, it is easy to cause a short circuit and fire. The insulation layer of ordinary BV and BVR wires is made of polyvinyl chloride. When burned, it will release a large amount of halogen-containing and toxic black smoke (hydrogen chloride, one of the components). Its toxicity index is 15.01, and people can only survive in this smoke. minute. In addition, in this black smoke, the visible distance is only 5-8 meters. This has made it difficult for firefighters to identify the direction, which has greatly hindered escape and rescue. In the fire, most people are trapped in smoke, poisoning and suffocation.
Ordinary BV and BVR wires have become the number one killer in electrical fires. So, how to avoid the safety hazards caused by the wire? It is the most effective method to select high-quality environmentally friendly halogen-free, temperature-resistant flame retardant and radiation cross-linked wires, because the radiation cross-linked wires are irradiated and cross-linked by high-energy electron beam generated by an electron accelerator to make insulation. The layer is changed from a linear molecular structure to a three-dimensional network structure, thereby greatly improving the temperature resistance, wear resistance, flame retardancy and the like of the wire.
The core material of Wal-Mart Rich Co., Ltd. is made of high-quality low-smoke halogen-free material (polyolefin), which is made by radiation crosslinking. It is the most advanced low-smoke and halogen-free environmentally friendly flame-retardant wire in China. The main features are as follows:
Temperature-resistant flame retardant: the insulation layer has a temperature resistance of at least 125 ° C, and the temperature is not melted at a high temperature of 250 ° C. It reaches the flame retardant grade B (the highest level of flame-retardant wires, suitable for civil buildings of any height and place), and is prevented under high load. Short circuit performance is superior.
Environmentally friendly and non-toxic: Fushe Electric Wire does not contain all kinds of plasticizers, does not contain harmful materials such as heavy metals, does not release harmful substances to human body (and ordinary BV (BVR) wires slowly release harmful substances), health and environmental protection. Even if forced combustion, the amount of smoke is only 1/10 of the ordinary BV (BVR) wire (visible distance is more than tens of meters), the release of water vapor, for the fire escape and rescue for valuable opportunities and time.
Long-lasting life: UV resistance, anti-aging, wear resistance, wire life in normal temperature environment for 100 years (and ordinary BV, BVR wire life expectancy is only 10-30 years).
