What is An Electric Arc? What is The Role of The Arc Protection Clothing?

Arc is a gas discharge phenomenon, refers to the body near high pressure electricity, but not contact, by the body's induction as a bridge formation of the jump, it can produce a high temperature of 29400 degrees Celsius, probably four times the sun's surface temperature, when the arc occurs, the huge energy is released in a very short time, can cause excitation Strong gas and electrical burns.

According to the type of current, it can be divided into AC arc, DC arc and pulse arc according to the state of arc, which can be divided into free arc and compressed arc, which can be divided into melting pole arc and non melting pole arc.

Knowing the arc, what harm does it do to the human body?

First and most serious, is direct death. In fact, even flame retardant clothing can not keep workers away from the risk of electric shock.

Secondly, it is the serious burns caused by the burning of the clothes. The workers do not have to be touched by the arc. The thermal radiation produced by the arc can melt the tools in a very short time, make the clothes fire, and cause injury and even fatal injury to the wearer.

Third, the serious burns caused by the clothes burrow. The explosion or shock force caused by electric arc will cause the daily clothes to crack and cause the skin of the operator to leak directly into high heat, flame or molten metal.

Finally, the fusion of synthetic fiber underwear causes serious burns. Even when the coat is not burning, the high heat produced by the arc is enough to melt the underwear made of synthetic fibers, causing serious and even fatal damage to the practitioners.

According to the OSHA statistics of the American Occupational Safety and Health Commission, more than half of the injury cases related to the arc are caused by the burning of workers' clothes. As a result, distributing appropriate and proper anti arc clothing for relevant workers has become a common safety standard in Europe and the United States.

Anti arc clothing, which is so famous, is a kind of protective clothing that can prevent the arc from damaging the human body to a certain extent. It has the functions of flame retardant, heat insulation and antistatic. It will not cause failure or deterioration due to washing.

Once the arc protection clothing is exposed to the arc flame or the heat, the internal high strength and low elongation bulletproof fiber will automatically expand rapidly, which makes the fabric thicker and the density becomes higher, forming a protective barrier to the human body.

The modern arc protection clothing has the characteristics of permanent anti arc. The raw material fiber itself has the property of flame retardant and has permanent protection. It will not reduce the protective performance because of repeated washing. It will not be ignited by heat and continue to burn and melt. It will not be deformed and other physical changes at high temperature, high tearing strength, wear resistance, and wear resistance. It is stable in size and is not easy to break. In the condition of arc explosion or flame, the fabric fiber will expand thicker, close the gap of the cloth surface, and generate the energy barrier to isolate the human body from the heat, so that the damage degree of the arc is reduced to a minimum.

Of course, the harm of arc to the human body is so great, and the protective function of the arc protection clothing is so strong. Do I have a clear regulation on the industry related to the arc? The answer is affirmative, and has "DL T 3202016 personal arc protection supplies general technical requirements" and other clear documents to do reference, only because of the current national conditions in China, arc protection clothing and other protective clothing has not been fully popularized.

As the leader of the occupational protective clothing industry, focusing on the R & D, production and sales of protective products, including arc protection clothing, flame retardant clothing, anti light cold suit, anti light raincoat suit, reflective vest, anti static clothing and other brand products, all with reference to national standard GB20 653, European standard EN471, EN343 and other industries professional standards production, and strive to create a leading brand of protective clothing industry.
