EHL series air core reactor products are used to limit short-circuit current, reactive power compensation and inductive high-voltage electrical appliances with equal displacement in the power system. The magnetic flux forms a loop through the air, so it is called air core reactor. High quality epoxy resin is used for vacuum impregnation and high temperature curing. The product features energy saving, good inductance linearity, accurate reactance value, uniform coil temperature rise distribution, and high dynamic and thermal stability. Strong short-circuit and overload resistance. Good insulation strength and electromagnetic field uniformity. Low loss and temperature rise. Long service life, basically maintenance free. Low noise. Flame retardant, pollution-free, small size, light weight and easy installation and use.
