The full name of RVV wire is copper core PVC insulated PVC sheathed flexible wire, also known as lightweight PVC sheathed flexible wire, commonly known as soft sheathed wireSheath wireOne of them. Mainly used for power lines, control lines, and signal transmission lines in electrical appliances, instruments, electronic equipment, and automation devices. Specifically, it can be used for anti-theft alarm systems, building intercom systems, etc.

RVVB is a copper core PVC insulated sheathed flat power cord, suitable for connecting wires in household appliances, lighting, security monitoring, etc.

RVVP is a soft conductor PVC insulated wire with an additional shielding layer and PVC sheathcableCopper core PVC insulated shielded PVC sheathed flexible cable, also known as electrical connection anti-interference flexible cable, rated voltage 300/300V, commonly used core number is 2-24, commonly used core diameter: 0.12 square, 0.2 square, 0.3 square, 0.4 square, 0.5 square, 1.0 square, 1.5 square, etc

The purpose of RVB and RVVB is equivalent

RVB is a flat unsheathed flexible wire

RVVB is a flat sheathed flexible wire

RVVB has an additional layer of protective sheath compared to RVB

Difference from RVS

RVSRVS

RVVB is a flat parallel sheathed wire

RVS is unsheathed twisted pair cable

Difference from RVV

RVVRVV

RVVB and RVV are both sheathed wires and have similar purposes.

The difference is that RVVB is flat and RVV is circular.

Meanwhile, RVVB generally only has a 2-core sheathed wire, while RVV has a range of 2-24 cores.

PVC insulated PVC sheathed flexible cable.

The meaning represented by letters

The letter R represents a flexible cord

The letter V represents insulation polyvinyl chloride (PVC)

RVV wire is a commonly used cable in weak current systems, with an indefinite number of core wires, two or more, and an outer PVC sheath. The arrangement between the core wires is not fixedThe function of the protective sheath

For example, rvv2 * 0.5 refers to two wires with an area of 0.5 square millimeters and an outer sheath. The purpose of the sheath is to

1. Protect the inner protective layer of the cable from mechanical damage and chemical corrosion;

2. Enhance the mechanical strength of the cable.

Inspection requirements

RVV refers to multi strand copper core flexible wire, which looks like the markings on the wire and the thickness of the skin compared to the core The cortex is usually made of polyvinyl chloride material The copper core is twisted into 19 strands The specifications generally include 1, 1.5, and 2.5 square millimeters When looking at the length of the line (100 meters per circle), the national standard line is 95-100 meters, and the non-standard line is about 90 meters.
