SWB cable, that is to say, galvanized steel wire braided cable, It is a type of special cable widely used in energy fields, communications and industrial automation. Its unique galvanized steel braided wire armor layer not only provides strong mechanical protection to the cable, but also gives it excellent electromagnetic shielding performance.. Below is a more detailed analysis of SWB cables.
I. SWB cables structure composition
The structure of cables SWB It is mainly composed of the following parts:
Conductor: It is usually made of bare copper wire, that meets the relevant standards of the International Electrotechnical Commission (the) and other relevant standards to ensure good electrical conductivity. Conductor material and specifications depend on the specific use and design requirements of the cable.
Isolation: It wraps around the outside of the conductor and serves to prevent current leakage and short circuits.. Insulation layer materials are mainly polyvinyl chloride (PVC), polyethylene (PE) and other polymeric materials, with good electrical insulation and heat resistance.
Galvanized Steel Wire Braided Armor Layer: It is the central part of the SWB cable, consisting of several galvanized steel wires tightly wound around the outside of the insulating layer in a specific braided shape. This armor layer not only improves the mechanical resistance of the cable, allowing you to withstand external pressures, animal blows and bites, but also provides excellent electromagnetic shielding, effectively reducing the effect of external electromagnetic interference on internal cable signals.
External cover: located outside the shielding layer, serves to protect the entire cable structure from the external environment. The outer sheath material is also usually PVC, PE and other polymeric materials, with excellent wear resistance, to corrosion and weathering.
2. In second place, The performance characteristics of SWB cables
High resistance: galvanized steel wire braid armor layer makes SWB cable have very high tensile strength and compressive strength, which can withstand large external loads without being easily damaged.
Good shielding: The mesh structure formed by the steel wire braiding layer can effectively shield external electromagnetic interference signals and protect the signals transmitted within the cable from being affected.
Abrasion resistance: The double protection of the outer sheath and the shielding layer gives SWB cables excellent abrasion resistance, allowing them to be used for a long time in difficult environments without easily wearing out.
Flexibility: Despite the robust layer of armor, SWB cables maintain a certain degree of flexibility, making installation and wiring in complex environments easier.
Weather resistance: The outer shell material has good weather resistance and maintains stable performance in various weather conditions..
3.Scope of application Cable SWB
SWB cables are widely used in the following fields:
Industrial automation: In robots, automation equipment, production lines and other occasions requiring frequent movement and bending, SWB cables can provide reliable power and signal transmission guarantee.
electrical system: In the electrical system, SWB cables can be used in control lines, distribution lines and other occasions to ensure the stability and safety of power transmission.
Communications industry: in communications base stations, data centers and other applications requiring high reliability and anti-interference capability, SWB cables can protect signal transmission from external interference.
Special environments: In special environments with corrosive gases or liquids, like oil, the chemical industry, mining, etc., SWB cables can resist erosion and destruction of cables by harsh environment.
4. SWB cable use precautions
Warp radio: In the process of installation and use, It should be noted that the bending radius of the cable should not be less than the minimum value specified in the product specifications to avoid damage to the cable due to excessive bending..
Avoid damage: in the handling and installation process, The cable must be prevented from being scratched or pinched by sharp objects., so as not to damage the insulation layer or armor.
Periodic inspection: The cable must be inspected and subjected to periodic maintenance to detect and solve possible problems in time., in order to ensure the normal operation and service life of the cable.
Fourthly, the future development trend of SWB cable.
- Environmental protection
With the growing global awareness of environmental protection, The cable industry also faces increasingly stringent environmental requirements. In the future, SWB cables will pay more attention to the application of environmentally friendly materials and waste recycling to reduce the impact on the environment. - Intelligent
With the rapid development of the Internet of Things, big data and other technologies, the cable industry will also usher in a wave of intelligent transformation. In the future, SWB cables will incorporate more smart elements, like intelligent monitoring, remote control and other functions, In order to improve the intelligent level and operational efficiency of the cable system. - Personalization
