BX wire and cable

BX refers to electric wire, which refers to copper core rubber insulated wire. Where "B" means wiring; "X" is the first letter of the Chinese pinyin of "rubber". The maximum operating temperature is 65 ℃, which is applied indoors.

Bx wire application range

Power system: The wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables (plastic cables, oil-paper power cables, which are basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables, branch cables (replacing some bus wires), electromagnetic wires and electrical equipment wires and cables for power equipment. Information transmission system: wires and cables used for information transmission system mainly include local telephone cable, television cable, electronic cable, radio frequency cable, optical fiber cable, data cable, electromagnetic cable, power communication or other composite cables. Mechanical instrument system: almost all other products except overhead bare wires are used in this part, but mainly power cables, electromagnetic cables, data cables, instrument cables, etc.

Main classification of bx wires

Bare wire body products: The main characteristics of this type of products are: pure conductor metal, without insulation and sheath layer, such as steel-cored aluminum stranded wire, copper aluminum bus, electric locomotive wire, etc; The processing technology is mainly pressure processing, such as melting, rolling, drawing, stranding/compression stranding, etc; The products are mainly used in suburban areas, rural areas, user mainlines, switch cabinets, etc. Power cable: This type of product is mainly characterized by extruding (winding) the insulation layer outside the conductor, such as overhead insulated cable, or twisting several cores (corresponding to the phase line, zero line and ground wire of the power system), such as overhead insulated cable with more than two cores, or adding a sheath layer, such as plastic/rubber sheathed wire and cable. Wire and cable for electrical equipment: The main characteristics of this type of products are: a wide variety of specifications, a wide range of applications, and a wide range of operating voltages of 1kV and below. In the face of special occasions, new products are constantly derived, such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free/low-smoke halogen-free cables, anti-termite, anti-mouse cables, oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables, medical/agricultural/mining cables, thin-walled wires, etc. Communication cable and optical fiber: with the rapid development of the communication industry, from the simple telephone and telegraph cable in the past to thousands of pairs of telephone cable, coaxial cable, optical cable, data cable, and even combined communication cable. The structural dimensions of these products are usually small and uniform, and the manufacturing accuracy requirements are high. Winding wire: winding wire is a kind of conductive metal wire with insulating layer for winding the coil or winding of electrical products. When it works, the magnetic field is generated by the current, or the induced current is generated by cutting the magnetic line of force to realize the conversion of electric energy and magnetic energy, so it is also called electromagnetic line.
