These fabrics can possess properties such as flame resistance, cut resistance, chemical resistance and arc resistance
. Protective clothing made from these fabrics are used protect workers exposed to extreme heat, flame, arc flash, and molten metals on a daily basis.
To protect industry workers from the thermal hazards of an electrical arc, DuPont showcased new Nomex A[R] brand fibre-based fabrics combining very high arc resistance
with optimized wearing comfort.
Rostami, "Effect of electric arc resistance
on the transition state due to the breakers switching in substations with air insulation," in Proceedings of the 7th International Power Electronics and Motion Control Conference (IPEMC '12), vol.
Actually RES signal gives the arc resistance
at quenching moment.
The total arc voltage [u.sub.arc], is made up of three separate parts: the anode and cathode drop voltage [u.sub.a+c], the drop voltage in the arc column, which is a function of the electric field strength E and the arc length h, and the drop voltage, that depends on current i and arc resistance
The mean arc resistance
is programmed as an exponential function of the rms current i.e.
It shows good dielectric strength, low electrical conductivity and excellent arc resistance
. The product has a wide range of applications including decorative signwork and display, window glazing, automotive components, sanitaryware, skylights and partitions.
Fault resistance of a typical earth fault is composed of three parts: arc resistance
, resistance of intermediate fault path and the ground resistance.
The use of self extinguishing UL94V-0 certified material in the cover and base provides high arc resistance
as well as high insulation resistance.
The site also outlines solutions in six technical challenge areas: arc resistance
; electrical insulation; electromagnetic interference (EMI) shielding; flame-retardant technology; high-temperature performance; and miniaturization.
