Towel rack heating time

The heating time is under the test voltage, and the time for the element to rise from the background temperature to the test temperature should be more than 15 minutes. The power of some companies is very accurate, for example: Taizhou Jiayi single-ended electric heating tube factory; here in Yancheng area, some companies can achieve +5% to -5%, and the resistance value deviation is only 1Ω, such as An Nai electric heating . For components with a rated power greater than 100W, it is +5% to -10% or 10W, whichever is greater.
