Power cables are used to transmit and distribute large-scale electrical energy in the main lines of the power system. Control cables directly transmit electrical energy from the distribution points of the power system to the power connection lines of various electrical equipment. The rated voltage of power cables is generally 0.6/1kV and above, and the control cables are mainly 450/750V. When power cables and control cables of the same specification are produced, the insulation and sheath thickness of the power cable is thicker than that of the control cable.

First of all, control cables are cables for electrical equipment, and power cables are two of the five major categories of cables.

The standard for control cables is 9330 and the standard for power cables is GB12706

The color of the insulated core of control cables is generally black with white characters, and low-voltage power cables are generally color-coded.

The cross-section of control cables generally does not exceed 10 square meters. Power cables are mainly used to transmit power and generally have large cross-sections.

Due to the reasons mentioned above, the specifications of power cables can generally be larger, as large as 500 square meters (the range that conventional manufacturers can produce). There are relatively few manufacturers that can make larger cross-sections, while the cross-section of control cables is generally Smaller, larger generally no more than 10 square meters.

In terms of the number of cable cores, power cables generally have 5 cores according to the requirements of the power grid, while control cables are used to transmit control signals and have a larger number of cores. According to the standard, most have 61 cores, but they can also be produced according to user requirements. .

What are the common types of mobile cables on the market?

(1) Wires and bare inner conductor products: refers to only conductors without insulation layers and other structures. Such as: copper, aluminum and various composite metal single wires; various structures of overhead transmission stranded wires, soft wiring, profiled wires and profiles, etc.

(2) Electromagnetic wires: Wires that cut magnetic lines of force in a magnetic field in the form of windings to induce current, or use current to generate a magnetic field are called electromagnetic wires. Such as enameled wire, fiber wrapped wire, inorganic insulated wire, etc.

(3) Power cables: Wire products used to transmit and distribute high-power electric energy in the main lines of the power system are called power cables. Such as: plastic cables of various voltage levels, oil-impregnated paper cables and non-drip cables, etc.

(4) Communication cables: Cables used to transmit audio and various telecommunications information above audio. Such as: local telephone cables, long-distance symmetrical communication cables, coaxial communication cables, telephone equipment cables and data cables, etc.

(5) Wires and cables for electrical equipment: Wires and cables for power connection that directly transmit electrical energy from the distribution point of the power system to various electrical equipment and appliances. Such as: wires and cables for electrical connections and control signals in various industrial and agricultural equipment. Such products are widely used and come in many varieties, and most of them must combine 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 also many special and specialty products. Such as: general insulated wires, installation wires, rubber-sheathed flexible cables, control cables, signal cables, special cables for aircraft, automobiles, and tractors, lead wires for motors and electrical appliances, mobile cables, cables for rolling stock, wires for radio devices, and mining cables , marine cables, agricultural cables, data cables, oil mine and detection cables, cables for field work, various high-voltage DC equipment wires, flexible cables, etc.
