It has the characteristics of heat resistance, flame retardant, non-combustible and non-melting and other fire protection and insulation. Washing causes failure or deterioration. Once the arc protected clothing comes into contact with the arc flame or heat, the internal high-strength and low-stretch ballistic fibers will automatically expand rapidly, thereby making the fabric thicker and denser, and quickly forming a protective layer, which will cause human skin contact with the arc heat To a minimum. Arc protected clothing can only properly protect body parts other than the head, neck, hands, and feet, so in arc-prone environments, it must be used with other arc-proof equipment, such as arc protected Insulation shoes and other equipment. When entering an arc environment, be sure to wear arc protected clothing and other supporting equipment. Do not expose the skin to the outside to prevent serious accident damage through the gap when the accident occurs.
