The power cable is 0.6/1kv such as VV, YJV
The control cable is 450/750v such as KVV, KVVP
General power cables are within 5 cores. Generally used for strong electricity.
There are many control cable cores, sometimes customers have different requirements, generally to 37 cores, but there are more cores.
Commonly used cable classifications are 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 of overhead transmission with stranded wire, flexible wiring, profiles and profiles.
(2) Electromagnetic wire: A wire that is in the form of a winding to cut a magnetic field line to induce a current, or a magnetic field that generates a magnetic field by a current is called a magnet wire. Such as enameled wire, fiber wrapped wire, inorganic insulated wire and so on.
(iii) Power cable: A wire product used to transmit and distribute high-power electrical energy in the main line of a power system, called a power cable. Such as: plastic cable of various voltage levels, oil-impregnated paper cable and no dripping.
(iv) Communication cable: A cable for transmitting various telecommunication information above audio and audio. Such as: local telephone cable, long-distance symmetric communication cable, coaxial communication cable, cable for telephone equipment and data cable.
(5) Wire and cable for electrical equipment: The electrical energy is directly transmitted from the distribution point of the power system to the power connection cable for various electrical equipment and appliances. Such as: wire and cable for electrical connection and control signals in various industrial and agricultural equipment. These products are widely used and widely used, 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 special products. Such as: general insulated wire, installation line, rubber sheathed flexible cable, control cable, signal cable, aircraft, automobile, tractor special cable, motor electrical lead wire, cable for rolling stock, radio device wire, mining cable, marine cable , agricultural cables, oil mines and detection cables, field work cables, various high-voltage DC equipment wires, flexible cables, etc.
The power cable is used to transmit and distribute large functional power in the main line of the power system, and the control cable directly transfers the electric energy from the power distribution point of the power system to the power connection line of various electrical equipment appliances. The rated voltage of the power cable is generally 0.6/1kV and above, and the control cable is mainly 450/750V. In the production of power cables and control cables of the same specification, the insulation and sheath thickness of the power cables are thicker than the control cables.
