The meaning of 450/750v is: 450 refers to the phase voltage, also known as the rated voltage, 750 refers to the line voltage, also known as the peak voltage, that is, the normal working voltage of the wire is 450V, and the maximum voltage of the wire is 750V Rated voltage refers to the optimal voltage for electrical equipment to operate normally for a long period of time, also known as the nominal voltage. When the working voltage of electrical equipment is higher than the rated voltage, it is easy to damage the equipment, and when it is lower than the rated voltage, it will not work properly, such as abnormal light emission of bulbs and abnormal operation of motors What is the testing fee The cost of testing 450/750V PVC insulated flexible cables is determined based on factors such as testing items and laboratory qualifications.
