Features of HF Litz Wires
Single wire of HF Litz Wire is coated with enamel.
HF Litz wires avoids losses due to skin effect and proximity effect.
Skin Effect is the tendency of an electric current to distribute itself within a conductor such that the current density near the surface of the conductor is greater thatn at its core. The higher the frequency, the larger the impact of skin effect. HF Litz wire counteract this effect by increasing the surface area without significant increase in the size of conductor.
Eddy currents which are generated through the fields of adjacent conductors also effect the performance of the single conductor. This is called proximity effect.
HF litz wires consists of bunched enameled wires.
The enamel insulations can be of temperature class 155, 180 , 200 , 220 or 2400C.
The enamel insulation on wires can be of Grade 1, Grade 2 or Grade 3 according to the customer requirement.
The HF litz wires can be provided with the additional insulations, in the form of yarns or tapes, which increases the electrical and mechanical values.
HF litz wires can be round or profiled (rectangular).
