Made of pure copper clad aluminum, high purity, anti-aging, high conductivity, strong current load capacity, lower resistance, fast and stable transmission. High-quality environmentally friendly PVC insulation, made of high-quality plastic material, with the characteristics of wear resistance, acid and alkali resistance, fire resistance, oil resistance, frost resistance, etc., and longer service life. Built-in tensile hemp rope The wire has built-in hemp rope, which fills the gaps between the wires and increases the tensile strength and toughness of the wires.
The raw material is PVC, which is safe, flame-retardant and more durable. The high-density polyvinyl chloride protective cover refuses to recycle old materials. It has good stability and impact resistance, is not easy to crack, and can be used with confidence. High flexibility, bending resistance, long service life, high flexibility, wear resistance, bending resistance, not easy to break, no fear of harsh environment wiring construction, safe to use. Low eccentricity, anti-breakdown, uniform sheath thickness, low eccentricity, not easy to heat up after long-term use, effectively preventing current breakdown and sparking.
BV single-core single-strand hard wire is generally used in fixed occasions and is a common model in household wiring.
Specifications above 10 square meters are composed of 7 copper wires and are mostly used in fixed buried environments. BVR single-core multi-strand soft wire is made of 7 or more copper wires twisted together. Because the wire is softer, it is mostly used in mobile power places and temporary power places. It is easy to install, drag and drop, and move. BVVB flat hard sheathed wire is made of 2 or more BV wires and is mostly used as decorative exposed wires.
Differences between flame-retardant wires and ordinary wires
1. Flame-retardant wires are mostly used in industrial and mining enterprises and hotels. They are not easy to ignite and extinguish immediately after leaving the fire.
2. According to the flame retardant level, they are divided into ZA, ZB, and ZC (ZR). Choose ZR and ZC specifications for home use.
