In our daily wiring, there's a distinction between strong and weak current. Included within weak current are RVV power cables, which are also multi-core wires. Speaking of flexible cables, we often think of RVS cables. These two types of cables will be the primary focus of our discussion. While they share some similarities in their uses, let's focus on the differences between them.
Introduction to RVV Power Cables and RVS Cables
RVV is also a type of cable, commonly known as sheathed cable. RVV cable stands for copper-core PVC insulated and sheathed flexible cable, also known as lightweight PVC sheathed flexible cable or soft sheathed cable. It's primarily used for power, control, and signal transmission lines in electrical appliances, instruments, electronic equipment, and automation devices. It can be used in burglar alarm systems and building intercom systems, among other applications.
RVV cable stands for copper-core PVC insulated twisted-pair flexible cable, also known as twisted-pair cable or "flower wire." Currently, this type of cable is primarily used in fire protection systems and is also known as "fire wire." Suitable for household appliances, small power tools, instruments, and power lighting. The dual white cores are used for direct connection to lamp sockets; the red and blue cores are used for fire protection and alarm systems; the red and white cores are used for broadcast and telephone lines; and the red and black cores are used for broadcast lines.
Differences between RVV power cables and RVS cables
RVV transmission lines are commonly used in low-voltage systems. Two or more RV lines are covered with a sheath. The inner core contains not only two cores, but also three-core, four-core, and six-core power cables.
The copper conductors of RVV power cables have the same outer sheath as RVS copper conductors, making them environmentally friendly. The copper conductors in RVV power cables are typically parallel and untwisted.
RVV cables are twisted-pair cables, consisting of two plastic-copper flexible RV cables twisted together. They are commonly used for public address systems, fire protection systems, and other applications.
When wiring, RVS cables can be used for straight lines without loops, eliminating the need to run cables through walls. RVV power cables are an alternative for trunk and multi-circuit wiring.
Today I will give you a brief introduction to the difference between RVV power cord and RVS wire.
