Many people can't tell what is a power cable and what is a control cable. To introduce you to what is a power cable.
Power cable is 0.6/1kv such as VV, YJV
The control cable is 450/750v such as KVV, KVVP
General power cables are generally used for strong electricity within 5 cores
There are more control cable cores, and sometimes customer requirements are different, generally to 37 cores, but there are also more cores.
Commonly used cable classification is divided into five categories:
(A) wire and bare inner conductor products: refers to only conductors, without insulation and other structures. Such as: copper, aluminum and various composite metal single wire; Various structures for overhead transmission of twisted wire, flexible wire, profile and profile, etc.
(2) Electromagnetic wire: in the form of winding in the magnetic field cutting magnetic field line induction to generate current, or through the current to generate magnetic field action wire called electromagnetic wire. Such as enamelled wire, fiber wrapped wire, inorganic insulated wire and so on.
(3) Power cable: wire products used to transmit and distribute high-power electrical energy in the backbone line of the power system, known as power cables. Such as: various voltage levels of plastic force cables, oil-impregnated paper cables and non-dripping and so on.
(4) Communication cable: transmission of audio and audio above a variety of telecommunications information used cables. Such as: local telephone cable, long-distance symmetrical communication cable, coaxial communication cable, telephone equipment cable and data cable and so on.
(5) Wire and cable for electrical equipment: wire and cable used for connecting the power supply of various electrical equipment and appliances directly from the distribution point of the power system. Such as: various industrial and agricultural equipment in the electrical connection and control signals of wire and cable. Such products are widely used and have a wide variety, and most of them must be combined with the characteristics of the equipment used and the environmental conditions used to determine the structure and performance of the product. Therefore, in addition to a large number of general purpose products, there are many special and specialty products. Such as: general insulated wires, installation wires, rubber sheathing flexible cables, control cables, signal cables, aircraft, automobiles, tractors special cables, electrical and motor cables, rolling stock cables, radio equipment with wires, mining cables, Marine cables, agricultural cables, oil and mining and detection cables, field work cables, various HVDC equipment with wires, flexible cables and so on.
The power cable is used to transmit and distribute large functional electric energy in the main trunk line of the power system, and the control cable transfers the electric energy directly from the distribution point of the power system to the power supply connection line of various electrical equipment and appliances. The rated voltage of power cables is generally 0.6/1kV and above, and the control cables are mainly 450/750V. When the power cable and control cable of the same specification are produced, the insulation and sheath thickness of the power cable is thicker than that of the control cable.
