Wirewound braking resistor, suitable for elevators and UPS systems
Wirewound braking resistors can be suitablefor rugged applications.
Two terminal extensions are fixed on both ends of aceramic tube on
whose surface winds wave-shaped alloy resistance wire and ahigh
temperature resistant and fireproof coating are applied. The
ceramic tubecan function as resistance wire skeleton and heat
radiator as well.
