BVR wire is a kind of soft wire for distribution cabinets, also called secondary wire. Insulated soft-wires using copper-core polyvinyl chloride, which are used in applications where flexible wiring is required. It is loved by the majority of electricians and building decoration personnel.
B series belong to the cloth wire, so the beginning with B, voltage: 300/500V;
V is PVC PVC, which is (plastic);
R is (soft) meaning, to be soft, is to increase the number of conductors;
BVR copper core PVC insulated soft wire.
Wire and cable specifications model list
First, wire and cable products are mainly divided into five categories:
1, bare wires and bare conductor products
The main features of this type of product are: pure conductive metal, non-insulating and sheathing layers, such as ACSR, copper and aluminum busbars, electric locomotive lines, etc.; the processing technology is mainly pressure processing, such as smelting, rolling, pulling System, stranding/pressing and stranding, etc.; products are mainly used in suburban areas, rural areas, user main lines, switch cabinets, etc.
2, power cable
The main features of this type of product are: Extruding (wrapping) the insulation around the conductor, such as overhead insulated cables, or strands of cores (corresponding to the phase, neutral and ground of the power system), such as over two core overhead insulated cables , Or increase the jacket layer, such as plastic / rubber sheathed wire and cable. The main process technologies include drawing, stranding, insulation extrusion (wrapping), cabling, armoring, sheath extrusion, etc. There are certain differences in the different process combinations of various products.
The products are mainly used in the transmission of electricity, electricity, electricity, electricity, electricity, electricity and electricity in high-voltage transmission lines, with large currents (tens of amps to several thousand amps) and high voltages (220V to 500kV and above).
3, wire and cable for electrical equipment
The main features of this type of product are: variety of specifications, a wide range of applications, the use of voltage in 1kV and below, in the face of special occasions continue to derive new products, such as fire-resistant cables, flame retardant cable, low smoke and halogen-free / low Smoke low-halogen cable, termite prevention, rat-proof cable, oil/cold resistance/temperature/wear resistance cable, medical/agricultural/mine cable, thin-walled wire, etc.
4. Communication cables and optical fibers (The company does not produce such products at present, so a brief introduction)
With the rapid development of the communications industry over the past two decades, the products have also been developing at an alarming rate. From the simple telephone telegraph cable in the past to the development of thousands of pairs of voice cables, coaxial cables, optical cables, data cables, and even composite communication cables.
The size of such products is usually small and uniform, and the manufacturing precision is high.
5, magnet wire (winding line) (The company does not produce such products at present, so a brief introduction)
Mainly used for various motors, instruments and meters.
Derivatives/new products of wire and cable:
The derivative/new product of wire and cable is mainly due to the requirements of different applications, different application requirements, and the convenience of equipment and the reduction of equipment costs, and the use of new materials, special materials, or changes in product structure. Huang score points fierce gap?
Use different materials such as flame-retardant cables, low-smoke and halogen-free/low-smoke and low-halogen cables, termite-proof cables, mouse-proof cables, oil/cold/heat-resistant cables, etc.;
Change product structure such as: fire-resistant cables;
Improve process requirements such as: medical cables;
Combination products such as: OPGW;
Easy to install and reduce equipment costs such as: prefabricated branch cables.
