Characteristics of arc protection clothing

1. Permanent arc protection: the raw material fiber has flame retardancy and permanent protection performance, and it will not reduce the protective performance due to repeated washing.

2. It will not be ignited by heat and will continue to burn and melt.

3. High temperature resistant, no deformation or other physical changes when encountered high temperature.

4. High tear resistance, good abrasion resistance, stable size and no cracking.

5. When the arc explosion or flame is encountered, the arc protection clothing fiber can expand thickening, close the gap of the cloth surface, produce protective barrier and isolate the body from heat to minimize the degree of damage.

The damage of the arc to the human body

Arc injury, usually refers to the electric arc heat caused by the arc heat generated by the ionized air produced by the ambient electric environment without contact current, and the other electrical damage is caused by the direct contact between the human body and the power supply, and sometimes causes the destruction of the internal and external body tissues. Generally speaking, people know more about accidental electric shocks, but in fact, the more dangerous part of the power industry is hidden arc damage. Unlike other electrical injuries, the damage of the arc is often unintentional, it is not directly touched, it is easy to be neglected and difficult to avoid, and direct contact with light clothes can cause serious burns or death of the workers.

Measurement of arc strength

The unit of arc magnitude is Cal/cm2 (calorie per square centimeter); it refers to the total energy per unit area, which is used to detect the intensity of the arc. The exposure of 1 Cal/cm2 is equivalent to a lighted cigarette butt on the fingertip for 1 seconds, and 1-2 Cal/cm2 will cause skin 2 grade burns.

According to the American NFPA Association, it is known that the arc injury is mainly caused by the enormous heat generated by the arc explosion, which causes the human body to burn. Therefore, the standard of using the arc energy is the grade standard for measuring the possible damage caused by the arc, that is, Cal/cm2.

The greater the ATPV value of arc protection clothing, the better the arc proof performance of arc protection clothing.
