Please explain in detail the difference between BVR and RVV cables and what cable to use under any circumstances! Please.
BVR cable: B refers to wires classified as wiring; V refers to PVC and polyvinyl chloride, also known as "plastic"; R means soft, which is made soft by increasing the number of conductors.
RVV cable: r stands for flexible cord; V stands for insulator polyvinyl chloride (PVC).
2. Rated voltage:
BVR cable: Rated voltage: the wire is immersed in water 1 hour, and it will not break down after being tested by AC 50Hz2500V(450/750V) and 2000V for 5 minutes.
RVV cable: rated voltage 300 V/500 V; There are 450/750V and 600/ 1000VRVV cables with higher rated voltage.
3. Working temperature:
BVR cable: the maximum working temperature shall not exceed 70℃, the maximum working temperature of BVR- 105 shall be 105℃, and the laying temperature of conductor shall not be lower than 0℃.
RVV cable:-30 degrees Celsius to-70 degrees Celsius.
4, the use of occasions:
BVR cable: special cord for power distribution cabinet, which is used in occasions where flexibility is needed when fixing wiring. It is suitable for AC power supply, household appliances, instruments and telecommunications equipment with rated voltage of 450/750V and below, and is mostly used in various flexible mechanical equipment.
RVV cable: sheath line, which is used for power line, control line and signal transmission line of electrical appliances, instruments, electronic equipment and automation devices. It is especially suitable for burglar alarm system and building intercom system. It is mainly used in flexible places such as light and medium mobile appliances, instruments and meters, household appliances and power lighting. It can transmit control signals and power signals, and is also suitable for laying in bridges and hoses. RVV cable products (high and low temperature resistance, corrosion resistance, cutting resistance, etc. ) is used in other special places.
