JB/T6213.1-6213.6 is a series of standards for motor lead wires. It specifies the standard and specific requirements for special lead wires under different motors and different working conditions. Each motor manufacturer should follow the actual selection and correct use of the motor to prevent it. Quality problems caused by improper selection and use of lead wires. JB/T6213.1 is a general requirement for cables for electric machines, while others are special requirements for different insulation levels or different working conditions.
