Wirewound braking resistor / tubular ceramic / high-voltage

king resistors can be suitable for rugged applications. Two terminal extensions are fixed on both ends of a ceramic tube on whose surface winds wave-shaped alloy resistance h temperature resistant and fireproof coating are applied. The ceramic tube can function as resistance and heat radiator as well.
