First, copper sheathed wire

BVV hard sheathed wire is a kind of sheathed wire, the difference with RVV soft sheathed wire is a hard wire, RVV is a soft wire.

The following are the parameters of the BVV hard sheathed cable

Full name: copper (aluminum) core PVC insulated PVC sheathed round hard sheathed wire, commonly known as hard sheathed wire.

Structure: BVV wire is composed of conductors, insulation and sheathing, of which the conductor is composed of copper conductor and aluminum conductor, generally copper conductor is used more, the edge and sheathing are polyvinyl chloride (PVC), to put it simply, that is, multiple strands of BV wire are composed of a layer of sheathing.

Standard: GB/T 8734-1998

Rated voltage: 450/750V

Temperature: Normal operating temperature 65℃

Color: Red/yellow/blue/green/black/white/yellow/green

Application: Suitable for AC voltage 450/750V and below power plant, daily appliances, instruments and telecommunications equipment for cable and wire, but also used for open wire.

Specifications: The commonly used BVV wire cores are single core, 2 core, 3 core, 4 core, etc., including 0.5mm2, 0.75 mm2, 1 mm2, 1.5 mm2, 2.5 mm2, 4 mm2, 6 mm2, 10 mm2. For example, the BVV2*1.5 wire is composed of two 1.5 square BV wires.

Two, soft sheath line

rvv cable is also known as sheathed cable or sheathed cable, because rvv appearance has a layer of obvious sheathed, to protect the inside of the wire, rvv cable full name PVC insulated PVC sheathed flexible cable, is an indispensable wire and cable in our lives, used in electrical, instrumentation and electronic equipment and automatic replacement devices with power lines, control lines and signal transmission lines, Specifically can be used for anti-theft alarm system, building intercom system, etc. The rvv cable we see in life is more as a power cord, that is, the power cable connected to the power supply board, and the outside layer of sheathing holds several rv flexible cables inside.
