The utility model relates to a resistor technical field, concretely relates to high -power wire resistor ware of cooled, its structure includes that first end plate, second end plate, at least two are used for wire -wound insulating tube, and the first end of each insulating tube is installed at first end plate together, and the second of each insulating tube end is installed at the second end plate together, and each thoroughly does away with intraductal the confessions cooling fluid of reason and flows past, thus each insulating tube feeds through and forms fluid passage, and the structure that each insulating tube feeds through includes: have two insulating tubes to locate the intercommunication and locate not feed through at the second end plate at first end plate, this resistor not only has great power, and has advantage small, that the radiating effect is good.
