What are the differences between explosion-proof cable and armor?

　　Explosion-proof fiber optic cables and armor are significantly different in several ways. Here is a detailed comparison of the two:

　　I. Definition and purpose

　　explosion-proof cable

　　Explosion-proof fiber optic cable is a type of fiber optic communication cable specifically designed for use in potentially explosive environments.

　　Uses: Widely used in hazardous locations in petroleum, chemical, aerospace, coal mining, automotive manufacturing, and medical equipment, for real-time monitoring, data tranSMission, and communication to ensure the stability and safety of communication transmission in these environments.

　　armor

　　Definition: Armor usually refers to a form of cable protection in which one or more layers of metal or non-metallic materials are added to the outside of the cable to enhance the mechanical strength and electrical properties of the cable.

　　Purpose: It is mainly used for cable protection in special environments such as underground and underwater, and plays the role of mechanical protection and electrical insulation. Armored cables are also often used to prevent rats and termites from biting and protect cables from external mechanical forces.

　　Structure and material

　　explosion-proof cable

　　Structure: generally includes core wire, insulating layer, filler, copper protective layer (or shielding layer), sheath and other components.

　　Material:

　　Core: Fiber optics.

　　Insulation layer: High-grade materials such as fluoroplastics are often used, which have the characteristics of high temperature resistance, corrosion resistance, and good chemical resistance.

　　Fillers: generally use mineral powders or special chemicals, which can play a role in fire and explosion prevention.

　　Sheath: generally use wear-resistant, corrosion-resistant, flame-retardant and other functional materials.

　　armor

　　Structure: mainly including core wire, insulation layer, armor layer, sheath and other components.

　　Material:

　　Core wire: Depending on the type of cable, it can be made of conductive materials such as copper and aluminum.

　　Insulation layer: Depending on the type and purpose of the cable, different insulation materials are used.

　　Armor layer: steel strip, copper strip, aluminum alloy strip and other materials are often used to withstand mechanical impact and tension.

　　Sheath: Commonly used sheath materials include PVC, PE, LSZH, etc.

　　III. Performance characteristics

　　explosion-proof cable

　　Explosion-proof performance: The use of explosion-proof materials and structural design can effectively prevent the generation of arcs, sparks, etc., and does not cause or spread fire in an explosive environment.

　　High-temperature resistance: Able to operate normally in high-temperature environments, ensuring the stability and reliability of communication systems.

　　Corrosion resistance: the use of corrosion-resistant materials and processes, capable of resisting chemical substances, acid and alkali corrosion.

　　Tensile strength: It has good tensile strength and wear resistance, and can adapt to complex installation environments and external forces.

　　armor

　　Mechanical protection: The armor layer can enhance the mechanical strength of the cable and prevent it from being damaged by external forces.

　　Electrical insulation: The armor layer can also provide electrical insulation, protecting the core wires inside the cable from external electrical interference.

　　Flame retardant and fire resistant: The armor layer can improve the flame retardant and fire resistant level of the cable and reduce the risk factor of fire.

　　IV. Application scenarios and purchase suggestions

　　application scenario

　　Explosion-proof fiber optic cable: suitable for communication and monitoring systems in petroleum refining, storage and transportation, the chemical industry, coal mines, automotive production lines, and medical equipment.

　　Armored cable: suitable for cable protection in special environments such as underground and underwater, as well as in situations that require mechanical impact and tension.

　　Buying suggestions

　　When selecting explosion-proof fiber optic cables, it is necessary to choose the corresponding explosion-proof grade and materials according to the actual use environment, temperature requirements, and the presence of chemical substances.

　　When selecting an armored cable, it is necessary to choose according to factors such as the cable's operating environment, mechanical strength requirements, and electrical performance requirements.

　　In summary, explosion-proof cables and armor are significantly different in terms of definition and use, structure and material, performance characteristics, application scenarios and purchase recommendations. When purchasing, you need to choose according to actual needs to ensure the normal operation and safety of the cable system.
