In this standard, usually the nominal value of the extended value of the test in considering the specified tolerance test. 3.2 Median medianvalue When the numerical values obtained by testing are arranged in ascending (or descending) order, if the number of values is an odd number, the value in the middle is Yes; if the number of values is even, the average of the two values is. 3.3 Rated voltage ratedvoltage Cable design, use and electrical performance test with the reference voltage. Note. In the AC system, the rated voltage U0/U said. U0 represents the distance between any of the main insulated conductors and "ground" (metal shield, ferrule, or surrounding medium) Voltage RMS; U is the RMS voltage between any two conductors in a multi-core cable or single-core cable system. The rated voltage of the cable is at least equal to With the nominal voltage of the cable system, this condition applies to both U0 and U values. In the DC system, the rated voltage U0 said, U0 conductor and screen The effective voltage between the shield. System operating voltage is not greater than 1.1 times the system nominal voltage. 3.4 Routine test routinetests The manufacturer performs tests on all manufactured lengths of finished cable to verify that all cables meet the specified requirements. 3.5 Sampletests The test on the finished cable sample by the manufacturer on the required frequency, or on some parts taken from the finished cable, Cable meets the requirements. 3.6 Type test typetests According to the general commercial principle of this standard contains a type of cable before the test carried out to prove that the cable has to meet Expected conditions of use of good performance. Note. The test is characterized by the fact that unless the cable material, design or manufacturing process changes may change the characteristics of the cable, or do not need to redo the test after doing so. 3.7 Electric car electricvehicles Including pure electric vehicles and hybrid (electric) cars. Pure electric vehicles are motors driven by the motor, the motor drive power from the car rechargeable battery or other energy storage Devices; hybrid (electric) vehicles are vehicles that are capable of powering at least two types of onboard energy storage. consumable fuel and renewable Charge energy/energy storage device. 3.8 Charging charging Adjusting the AC or DC power supply (power supply) to a standard voltage/current to power the EV battery pack can also be Car electrical equipment supply.
