What is YJLV Cable?
YJLV is an aluminum core power cable, with the model name: aluminum core cross-linked polyethylene insulated polyvinyl chloride sheathed power cable.
The meaning of YJLV cable is: YJ - cross-linked polyethylene insulation; The material of the wire core is aluminum. V - PVC sheath.
The working temperature of YJLV cable is 90 ℃, which is the highest rated working temperature of the conductor; The maximum temperature of the conductor short circuit shall not exceed 250 ℃, and the longest time shall not exceed 5 seconds; The installation and laying temperature is for cable installation, and the laying temperature is not lower than 0 ℃; Laid in the air at an ambient temperature of 40 ℃; Lay in soil at an ambient temperature of 25 ℃.
YJLV and YJV are both power cables. YJV is a copper core power cable, while YJLV is an aluminum core power cable. The difference lies in the conductor material.
The usage characteristics of YJLV cable: the maximum rated working temperature of the cable conductor is 90 ℃, the maximum working temperature should not exceed+70 ℃, the short circuit for 5 seconds should not exceed 160 ℃, and the ambient temperature during laying should not be lower than 0 ℃.
Characteristics of YJLV cable
The working temperature range of YJLV cable is wide, with a maximum rated working temperature of 90 ℃ for the conductor and a maximum working temperature not exceeding+70 ℃. The cable temperature should not exceed 160 ℃ within a 5-second short circuit time, and the ambient temperature during laying should not be lower than 0 ℃. In addition, YJLV cables are laid under different conditions, such as an ambient temperature of 40 ℃ in air and 25 ℃ in soil.
Application of YJLV cable
YJLV cables are suitable for high-voltage, medium voltage, and low-voltage power transmission in power systems, and can meet the needs of different voltage levels and application scenarios. Its model consists of insulation materials, conductor materials, sheath materials, and applications, such as YJLV22, YJLV32, etc. When selecting YJLV cables, comprehensive consideration should be given to factors such as actual application scenarios, usage requirements, and budget to ensure that the quality and safety performance of the cables meet national standards, in order to ensure the stable operation of the power system.
As a high-performance cable for power transmission and distribution, YJLV cable has won praise from professionals for its excellent performance and wide application. Understanding the structure, characteristics, and application of YJLV cables is an important step for professionals to enhance their professional competence and optimize power system design.
Advantages of YJLV cable
Good electrical performance: YJLV cables use cross-linked polyethylene as insulation material, which has good electrical properties such as high insulation resistance, low dielectric loss, and good corona resistance, ensuring the safety and reliability of power transmission.
Good mechanical performance: The conductor of YJLV cable is made of aluminum core material, which has good mechanical properties such as high tensile strength and good bending performance, and can adapt to different installation environments and usage conditions.
Good corrosion resistance: The sheath of YJLV cable is made of polyvinyl chloride material, which has good corrosion resistance and can adapt to different soil environments and climate conditions, extending the service life of the cable.
Economy: The price of YJLV cables is relatively low, which has good economy and can reduce engineering costs.
