Essential information

Type: Building Wire-PVC insulated rigid cable (CU/PVC)

Conductor material: made of high purity oxygen-free copper, the copper wire is bright on the outside, low resistivity and excellent electrical conductivity.

Insulating material: PVC (PVC), environmentally friendly and safe, fire retardant, extinguish immediately away from open flame.

Specifications

nominal cross:

2.5mm², suitable for socket wire, switch wire, power line, etc.

4mm², often used for large power electrical equipment connection.

6mm², used for household bus and other occasions that require large current transmission.

10mm², used for villa entrance bus and other occasions that require large current transmission.

Conductor structure: For 2.5mm², the conductor structure is usually 1/1.78mm, that is, a single copper wire with a diameter of about 1.78mm.

Insulation thickness: 2.5mm² The insulation thickness of the wire is usually 0.8mm, and the average insulation thickness shall not be less than this value, and the insulation to the thin point shall not be lower than the specified minimum value.

Outer diameter: 2.5mm² The nominal outer diameter of the wire is about 3.3mm. The actual outer diameter may vary in production, but it will be controlled within a certain range.

Behaviour of electricity

Insulation resistance: BV line has a high insulation resistance to ensure the safety and stability of current transmission.

Physical characteristics

Color: There are usually red, yellow, blue, green and other colors to distinguish different wire functions (such as fire wire, zero wire, ground wire, etc.).

Flexibility: Single-core hard conductor, less flexible than multi-core soft wire, but has high stability in fixed wiring.

Application scenarios

Home Renovation: 1.5mm², 2.5mm², 4mm², and 6mm² wires are widely used in home renovation, especially the 2.5mm² wire, which is commonly used for wiring circuits such as sockets, switches, and lighting. The 4mm² and 6mm² wires are suitable for applications requiring higher current transmission, like connecting high-power electrical appliances.

Construction engineering: In construction engineering, it is also often used in indoor wiring and electrical equipment connection. Its excellent electrical performance and chemical stability make the power supply in buildings more safe and reliable.

Industrial field: In industrial production, it can be used to connect various equipment and machines to provide stability for the production linepowerSupply. BV lines of different sections can be selected according to specific power demand.

Public facilities: It is also widely used in public facilities such as shopping malls, hospitals and schoolsPower linesIn the laying and renovation of the project.
