YJLV is an aluminum-core power cable, also known as a cross-linked polyethylene insulated, PVC-sheathed power cable. It is designed for indoor installation, trenches, and ducts, and can also be buried in loose soil. It cannot withstand external forces. When laid underground, YJLV cables can withstand mechanical forces but not significant tensile forces. Below, we will explain in detail about YJLV cables.
What is a YJLV cable?
YJLV is an aluminum-core power cable, also known as a cross-linked polyethylene insulated, PVC-sheathed power cable.
YJLV cable means:
YJ = Cross-linked polyethylene insulation;
L = Aluminum core material.
V - PVC sheath.
YJLV cable operating temperature: The conductor's maximum rated operating temperature is 90°C. The conductor's short-circuit temperature must not exceed 250°C, with a maximum duration of no more than 5 seconds. The installation and laying temperature must be no less than 0°C. The ambient temperature for laying in air is 40°C, and the ambient temperature for laying in soil is 25°C.
Both YJLV and YJV are power cables. YJV is a copper-core power cable, while YJLV is an aluminum-core power cable. The difference lies in the conductor material.
YJLV cable features: The cable conductor has a maximum rated operating temperature of 90°C, a maximum operating temperature not exceeding +70°C, a 5-second short-circuit temperature not exceeding 160°C, and an ambient temperature of no less than 0°C during installation.
What are the YJLV cable models and applications?
YJLV: Aluminum-core, cross-linked polyvinyl chloride insulated, polyvinyl chloride sheathed power cable. Designed for fixed installation indoors, in tunnels, and in ducts. The cable cannot withstand mechanical forces.
ZA(B, C, D) - YJLV: Aluminum core, cross-linked PVC insulated, PVC sheathed, flame-retardant Class A(B, C, D)O power cable.
YJLV 22: Aluminum core, cross-linked PVC insulated, PVC steel tape armored, PVC sheathed power cable. Because it is installed indoors, in tunnels, and in ducts, the cable must withstand mechanical forces.
ZA(B, C, D) - YJLV 22: Aluminum core, cross-linked PVC insulated, PVC steel tape armored, PVC sheathed, flame-retardant Class A(B, C, D) power cable.
The above is an explanation of YJLV, and I believe you have a good understanding of it. Aluminum core cables are prone to breaking after repeated bending, while copper core cables are less prone to breaking. In terms of elasticity, copper core cables are 1.7-1.8 times higher than aluminum core cables. Therefore, they cannot withstand external forces. Therefore, they are designed for fixed installation indoors, in tunnels, and in ducts.
