When renovating a home and purchasing electrical wiring, many people assume that the thicker the wire, the better the quality, and therefore the safer and more reliable it is. This is actually a misunderstanding. The cross-sectional thickness of the wire should be determined based on the power rating.
For home renovations, 2.5 square millimeter wire is sufficient for common switches, sockets, and lamps. However, for larger electrical appliances like air conditioner wiring, kitchen wiring, and electric water heaters, special wiring is required, and 4 square millimeter wire is required to ensure overload protection.
Household Electrical Wiring
1. PVC Insulated and Sheathed Round Cable (BVV)
BVV is the full name for copper-core PVC-insulated and polyethylene-sheathed round cable. It is also known as light PVC-sheathed cable and commonly known as hard-sheathed cable.
Scope of Application: This product is suitable for power plants and household appliances with AC voltages of 300/500 volts and below. It can also be used for surface mounting of electrical wiring.
Product Features: Long-term operating temperature: No more than 70°C. The temperature for fixed-laying cables (wires) must not drop below 0°C. BVV has one more sheath than BV. Available in standard, flame-retardant, and fire-resistant versions.
2. Copper Core PVC Insulated Flexible Wire
UHV wires are made of PVC for insulation and sheathing. Based on their performance, these products can be classified into three categories: insulating, flame-retardant, and fire-resistant. Each category has different applications.
Scope of Application: Suitable for AC rated voltages up to 450/750V. Suitable for use in flame-retardant applications for electrical equipment, instrumentation, telecommunications equipment, power plants, and fixed lighting lines.
We recommend choosing high-quality wire and cable from reputable brands, as these brands generally have professional technical R&D teams and efficient service teams. They carefully select high-quality raw materials to create high-quality home wiring, ensuring peace of mind.
