Working principle and characteristics of arc flash protection coverall
Flame-resistant and arc flash protection coverall helps protect workers against burn injuries in areas with sparks, open flame, and other potential fire hazards. Also called FR clothing, this arc protective clothing resists ignition and helps insulate against heat. It includes flame-resistant garments made of materials that naturally resist burning or melting and flame-retardant garments that are chemically treated to self-extinguish. Arc flash protection coverall are a specialized FR clothing typically worn when working with or near electrical equipment where electric arcs may heat surrounding air to extreme levels that can set standard clothing on fire. Aluminized clothing reflects radiant heat to help maintain a safe body temperature.
The arc protected clothing is a high-tech protective suit made of permanent arc-proof fabric. It has many unique features. First, let's take a look at the principle of arc protected clothing, which is probably the following. Arc-flash protection clothing has a good protective effect on arc damage, mainly due to the use of high-tech materials. The material has the characteristics of permanent fireproofing, insulation, etc., such as heat resistance, flame retardant, non-combustible, non-melting and H-class electrical insulation. It will rapidly expand when the arc explosion occurs, and the fabric is carbonized to make the arc-proof clothing density. Increase and thicken, quickly form a protective layer, so that the contact damage between human skin and arc heat is minimized.
Features of arc flash protection coverall :
1. Permanent arc prevention: The raw material fiber itself has flame retardant properties and is permanently protected, so that the protective performance is not reduced due to multiple washings.
2, will not be ignited by heat and continue to burn, melt down.
3, high temperature resistance, deformation and other physical changes will not occur in case of high temperature.
4, high tear strength, wear resistance, dimensional stability, not easy to break.
5. Under the same protection level, it is lighter than other flame retardant overalls made of permanent flame retardant materials.
6, anti-arc fabric contains natural plant fiber, with high quality breathable and moisture permeability.
