I. BV/BVR/RV Wire Usage:
General purpose single-core hard or multi-stranded conductor without sheath wire, suitable for AC voltage 450/750V and below power devices, daily appliances, instruments and telecommunications equipment with cable wire. With acid and alkali resistance, oil resistance, moisture, mold and other characteristics.
Second, the wire model and name:
1. Classification and use is used to distribute the current with, belongs to the cloth wire class, with the letter “B”;
2. conductor material is copper, with the letter “T”, copper core conductor omitted from the cloth wire;
3. Insulation material is polyvinyl chloride, with the letter “V”;
4. cloth wire structure is simple, in addition to the above three points, some have a sheath, sheath material for the PVC is also expressed in the letter “V”; sheath material for the rubber is expressed in the letter “X”. There is no sheath and the back of no need to indicate.
Such as BVV copper core PVC insulated PVC sheathed round wire.
Third, the common BV wire diameter:
Common BV wire diameter: 0.12 square, 0.20 square, 0.30 square, 0.35 square, 0.50 square, 0.75 square, 1 square, 1.5 square, 2.5 square, 4 square, 6 square, 10 square, 16 square, 25 square, 35 square, 50 square, 70 square, 95 square, 120 square, 150 square, 185 square, 240 square and so on. Square, etc.
Fourth, what is the cloth wire? Cloth wire specifications and applications
Electric wires are categorized into electromagnetic wires and general-purpose insulated wires according to their use. Insulated wires are also known as cloth wires.
Insulated wire (cloth wire) is the wire covered with insulation, including all kinds of connection and installation wires.
Before we talk about the cloth wire specification number, let's recognize the meaning of the letters in the cloth wire specification number:
B (B) - the first letter indicates wiring, the second letter indicates glass wire preparation.
V (V) - the first letter denotes polyethylene (plastic) insulation, the second letter denotes polyethylene jacket.
L (L) - aluminum, without L means copper
F (F) - composite
R - flexible wire
S - twisted
X - insulated rubber
