This standard specifies the use of single copper for continuous use at a nominal voltage of 600V, a maximum frequency of 2000Hz, and a temperature below 280℃ (ambient temperature + heat generation), and for use that can withstand temperatures of 400℃ for a limited time. Specify the dimensions, conductor resistance and mass of cables made of conductors. The cable shall maintain a certain value of dielectric strength when exposed to a flame at 1100 °C for 5 minutes.
