Symbols and uses of armored aluminum core cables

　　The symbols and uses of armored aluminum core cables are detailed as follows:

　　Detailed explanation of symbols

　　The type of armored aluminum core cable is usually composed of multiple parts, each of which represents a different meaning. Here are some common symbols and their interpretations:

　　YJ: indicates the use of cross-linked polyethylene insulation material. Cross-linked polyethylene is a high-performance insulating material with excellent electrical properties and heat resistance, suitable for high voltage, high current and other occasions.

　　LV: Represents aluminum conductor. In cable models, L usually stands for aluminum conductor, while T (although omitted in most cases) stands for copper conductor. Therefore, YJLV stands for XLPE insulated aluminum conductor cable.

　　V: In some models, V may denote PVC sheath, but in armored cables, it is more often used as part of the model number, combined with other characters to denote a specific cable type.

　　Numbers: such as 22, 32, 42, etc. These numbers usually indicate the type and construction of the cable armor. For example, 22 indicates steel belt armor, 32 indicates thin wire armor, and 42 may indicate steel belt or wire rope armor (depending on the manufacturer and industry standards).

　　Other characters: such as L (aluminum core), T (copper core, but usually omitted), D (no drip), P (dry insulation), etc. These characters are used to further describe the characteristics or uses of the cable.

　　Second, common models and uses

　　Here are some common types of armored aluminum cable and their uses:

　　YJLV22: XLPE insulated steel strip armored aluminum core power cable. This cable has excellent electrical properties and mechanical strength, and is suitable for power tranSMission and distribution in indoor, tunnel, cable trench and pipeline.

　　YJLV32: Cross-linked polyethylene insulated fine steel wire armored aluminum core power cable. Compared with YJLV22, this cable has higher mechanical strength and tensile strength, and is suitable for high voltage, high current, large span and occasions that require greater external force.

　　VLV22: PVC insulated steel strip armored aluminum core power cable. Although the insulation material is different, this cable also has excellent mechanical strength and electrical properties, suitable for general power transmission and distribution occasions.

　　III. Detailed explanation of uses

　　Armored aluminum core cables are widely used in various applications due to their excellent electrical properties, mechanical strength, and corrosion resistance.

　　Power transmission and distribution: Armored aluminum core cables can be used for power transmission and distribution in urban power grids, rural power grids, industrial and mining enterprises, and other occasions.

　　Building wiring: In high-rise buildings, commercial complexes, residential quarters, and other buildings, armored aluminum core cables can be used for indoor power wiring to provide a stable and reliable power supply.

　　Industrial applications: In the fields of petroleum, chemical industry, metallurgy, machinery, etc., armored aluminum core cables can be used for power connection and control of various equipment.

　　Special occasions: such as underwater, shaft, tunnel and other special occasions, armored aluminum core cable is widely used for its excellent tensile strength and waterproof performance.

　　In short, armored aluminum core cable has become an important power transmission and distribution equipment because of its unique performance and wide application field. When selecting and using, the appropriate cable type and specification should be selected according to the specific occasion and needs.
