In daily life, control cables play a pivotal role in the electrical industry. Control series cables are mostly used in control system lines. Depending on the place of use, the structure, material and model of the cable are also different.
1.Control cables are suitable for industrial and mining enterprises, energy and transportation departments, and are used for control of AC rated voltage below 450/750 volts, adjacent to and protecting lines. PVC insulated and PVC sheathed control cables.
2.Control cables have high fire resistance. Within a certain period of time, they will not short-circuit or short-circuit faults when directly burned by flames.
3.They are suitable for various occasions with high fire hazards and high importance of fire safety, and are used as connecting wires between electrical equipment and control systems.
4.The control cable has low smoke exhaust when heated, and it is composed of thermoplastic or thermosetting materials that do not contain halogens. It is suitable for use as a control connecting wire in places with dense personnel and low air density.
Control cables are widely used in life, covering many fields from household electricity, communication networks to urban infrastructure.
In family life, cables are the bridge connecting power supply and electrical equipment. For example, power cables are the core part of the home electrical system, used to distribute electricity from the power supply to various electrical equipment. Weak current cables, such as network cables, telephone cables, and TV coaxial cables, are used to transmit data and signals. For high-power electrical appliances, such as air conditioners, water heaters, etc., special high-temperature resistant cables, such as RVV cables, are required to effectively carry high current loads and ensure electricity safety.
With the popularization of the Internet and the rapid development of information technology, the role of cables in communication networks has become increasingly important. Fiber optic cables transmit data with optical signals, with the advantages of high speed, large bandwidth and low latency, and are widely used in home broadband, data centers and long-distance communications. Coaxial cables and twisted pair cables are also widely used in Ethernet to support LAN connections. Their structural design effectively reduces electromagnetic interference and improves the stability of network transmission.
Cables also play a vital role in urban infrastructure. Modern cities’ power supply mostly adopts underground cable laying, which beautifies the urban environment and reduces the risk of power lines being affected by the external environment. The public lighting systems of urban roads, parks and squares all rely on cables for power transmission. Reliable lighting cables can ensure nighttime lighting in public places and provide citizens with a safe travel environment.
In summary, the application of control cables in homes, communication networks and urban infrastructure reflects its indispensable role in modern life. From power distribution to data transmission to urban lighting, they are inseparable from the support of control cables.

Overhead cables are composed of two or two groups of transmission lines, and transmission lines are what we call cables.
The number of cable cores is selected based on comprehensive consideration of multiple factors to ensure the rational use of the cable.
Copper core cables have excellent electrical conductivity, thermal conductivity and good mechanical strength.
