Scope of Application: This product is suitable for power, household appliances, instruments, and telecommunication equipment with a rated AC voltage (U0/U) of 450/750V and below. Usage Characteristics: 1. The rated voltage U0/U of the cable is 300/300V. 2. The long-term allowable operating temperature shall not exceed 70°C. 3. Short-circuit temperature: In the event of a short circuit in multiple cables or multi-core cables (maximum duration not exceeding 5 seconds), the maximum conductor temperature shall not exceed 160°C. 4. When installing and laying cables, the bending radius must be greater than the specified value. For cables with an outer diameter greater than 25mm, the bending radius shall not be less than 6 times the outer diameter of the cable; for cables with an outer diameter less than 25mm, the bending radius shall not be less than 4 times the outer diameter of the cable. 5. When laying PVC insulated and sheathed cables, the ambient temperature should not be lower than 0°C. Main Performance Indicators: 1. Maximum DC resistance of the conductor at 20°C: 7.98 Ω/km. 2. Withstand AC voltage of 2000V for 5 minutes without breakdown. Specification: 60227IEC53(RVV) - 3*4 mm2 Voltage Rating: 300/500V Implementation Standard: GB/T5023-2008
