Characteristics of YJLV cable: The maximum rated working temperature of the conductor of the cable is 90 ℃, and the maximum working temperature is less than or equal to+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 ℃.
YJLV cables can be laid indoors, in trenches and pipelines, or buried in loose, insulated PVC sheathed power cable soil, and cannot withstand external forces. When YJLV cables are laid underground, they can withstand mechanical external forces but cannot withstand large tensile forces.
PVC insulated power cables have good electrical performance and chemical stability. Simple in structure and convenient to use, suitable for fixed installation on transmission and distribution lines with AC 50Hz and rated voltage of 1kV and below. Among them, the five core power cable is designed to adapt to the development and safety performance needs of the distribution system. It separates the neutral and neutral lines in low-voltage distribution system engineering, making the system operation more stable and ensuring the safety of workers.

Usage characteristics
