Every family needs electricity, and electricity and wires are inseparable. Wires are important objects that need to be carefully purchased for every home decoration. What type of household electrical wiring is it? What is the difference between wire and cable? Next, the editor will answer one by one for you. The difference between wire and cable. Cable: Insulated conductors consist of one or more insulated conductors placed in a hermetic sheath. It can add a protective overlay to the transmission. Distribute electrical energy or transmit electrical signals. The main difference between it and ordinary wires is that the cable size is large and the structure is complex. The cable is mainly composed of four parts: wire core. Insulation. Sealed jacket and protective cover. According to its use, it can be divided into power cables, communication cables and control cables. Tips: The wires used for circuit decoration are usually called wires and cables, and there is no strict boundary between wires and cables. Cables are generally not used for home improvement, and wires meet the requirements. Wire A wire consists of one or several flexible wires surrounded by a light and flexible sheath, a conductive metal wire for carrying current. Comes in various forms, such as solids. Twist or foil braid. According to the insulation condition, it can be divided into bare wire and insulated wire. Classification of household wires. 1. Hard wires are professionally called BV wires, mainly used for power supply, lighting, sockets, and air conditioners, and are suitable for cables and wires of power devices, household appliances, instruments, and telecommunication equipment with AC voltage 450/750V and below. The hard line has a certain hardness, and it is more convenient to straighten the corners. 2. Flexible wires are professionally called BVR wires, which are suitable for power devices with AC voltages of 450/750V and below. Household appliances. Cables and wires for instrumentation and telecommunications equipment, such as distribution boxes. The flexible wire is more complicated than the hard wire, and the flexible wire of the high-frequency circuit has a larger carrying capacity than the hard wire. 3. Hard. Soft wires (weak wires) are composed of single and several copper core wires, generally referring to network cables, wires and cables with low voltage. 4. Classification of common specifications and models of electric wires. The square of the wire refers to the size of the wire. A common size is 1.5 square. 2.5 square meters. 4 square. 6 square. 10 sq. The square of the wire is the square millimeter, which refers to the cross-sectional area of the wire and wire. .
