Wirewound resistors WIREWOUND POWER RESISTORS
These units feature an open helical wire element wound around a grooved porcelain core. This type of open element will take considerably more overload than enameled type resistors and also cool much quicker as each turn of the wire is exposed to the cool ambient air.
