The generalized wire and cable is also referred to as the cable. The cable in the narrow sense refers to the insulated cable. It can be defined as an assembly consisting of the following parts, one or more insulated cores, and their respective possible cladding, overall protective layer and outer protective layer. The cable may also have additional uninsulated conductors. Wire and cable are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion.


The important role of wire and cable in social development, u wire and cable are everywhere, u wire and cable is the blood vessel of the industry, the nerve of the society, and the heart of the motor. u The 21st century will be the world of wire (wire and cable).


UL 3271 Cable classes are classified by their use

  • Bare wires
  • Winding wire
  • Power cables
  • Communication cables and communication optical cables
  • Wires and cables for electrical equipment


The basic structure of wire and cable

  1. Conductor: an object that conducts current, and the specifications of wires and cables are represented by the cross-section of the conductor.
  2. Insulation: The outer insulating material is rated according to its withstand voltage.


Similar to UL 3271 Cable common cable types


  • BV: Indicates single copper core PVC ordinary insulated wire without sheath. It is suitable for wires and cables for power devices, household appliances, instruments and telecommunication equipment with AC voltage of 450/750V and below.
  • BVR: Indicates polyvinyl chloride insulation, copper core (soft) cloth wire, often referred to as flexible wire. Because the wire is relatively soft, it is often used in the connection of electric drag and motor and the occasion where the wire often moves slightly.
  • BVV: Indicates copper core PVC insulated PVC round sheathed cable, copper core (hard) cloth wire. Often referred to as sheathed wire, single-core is round, double-core is flat, often used for surface-mounted wires.
  • BVVB: Indicates copper core PVC insulated PVC flat sheathed cable. It is suitable for applications requiring high mechanical protection and humidity. It can be applied in the open or in the dark.
  • SYV: Solid polyethylene insulated RF coaxial cable. Applicable to closed-circuit monitoring and cable TV projects.
  • RG stands for Physically Foamed Polyethylene Insulated Cable, which is commonly used in the transmission of data analog signals in the coaxial optical fiber hybrid network (HFC), as well as video transmission, communication systems and signal control systems.
  • SYWV: Physically foamed polyethylene insulated cable TV system cable, video (RF) coaxial cable (SYV, SYWV, SYFV) is suitable for closed-circuit monitoring and cable TV projects.
  • RVV: Indicates copper core PVC insulated PVC sheathed round connection flexible cable. Applicable to building intercom, anti-theft alarm, fire protection, automatic meter reading and other projects.
  • RVVP: Indicates soft copper core stranded round PVC insulated PVC sheathed flexible wire. Applicable to building intercom, anti-theft alarm, fire protection, automatic meter reading and other projects.
  • BVVP: Indicates hard copper core flat PVC insulated PVC sheathed, copper mesh shielded wire.
  • RVS: Indicates copper core PVC stranded connection wire. Commonly used in household appliances, small power tools, instrumentation, control systems, broadcast audio, fire protection, lighting and control lines.

The difference between power cable and ordinary wire in structure


1. The difference between materials


Ordinary wire is a conductive metal wire used to carry current. It has the form of solid, stranded or foil braided. UL 3271 Cable category consists of one or more insulated conductors placed in a sealed jacket. The difference between wires and cables is that wires are generally smaller in size and simpler in structure, but cables are sometimes classified as generalized wires.

2. The difference in use


The bare wire does not cover any insulating layer or protective layer of the wire. In addition to being used as a wire for transmitting electrical energy and information, it can also be used to manufacture components and connecting wires for motors and electrical equipment. Generally, copper, aluminum, copper alloys, and aluminum alloys are used. . Cables are used to transmit, distribute electrical energy or transmit electrical signals. According to their uses, cables can be divided into power cables, communication cables and control cables. New energy cables are UL3271Cable.


3.Structural differences


The main difference between power cables and ordinary wires is that the cables are larger in size and more complex in structure. Conductive core of the cable: Made of highly conductive material. Insulation layer: The insulating material used for the cable should have high insulation resistance, high breakdown electric field strength, and the cable is usually classified according to the insulating material.
