YJLV aluminum core power cables are laid indoors, in trenches and pipelines, and can also be buried in the soil of loose, insulated PVC sheathed power cables, which cannot withstand external forces. When the YJLV cable is laid underground, it can withstand the mechanical external force, but it can not withstand large tensile force. Then let's talk about the knowledge of YJLV cable in detail.

YJLV Aluminum core power cable: aluminum core crosslinked polyethylene insulated polyvinyl chloride sheathed power cable.

The meaning of YJLV cable is: YJ- cross-linked polyethylene insulation; L-core material is aluminum. V-polyvinyl chloride sheath.

YJLV cable operating temperature is rated conductor operating temperature 90℃; Conductor short-circuit temperature temperature shall not exceed 250℃, the time shall not exceed 5 seconds; The installation and laying temperature of the cable shall not be lower than 0℃; The ambient temperature in the air is 40 ℃; The ambient temperature in the soil is 25℃.

YJLV and YJV are power cables, YJV is a copper core power cable, YJLV is an aluminum core power cable, the difference is the conductor material.

The operating characteristics of YJLV cable: the rated working temperature of the cable conductor is 90 ° C, the working temperature shall not exceed +70 ° C, the short circuit shall not exceed 160 ° C for 5 seconds, and the ambient temperature shall not be lower than 0 ° C when laying.


In addition, YJLV cables have excellent weather resistance and can operate normally in a variety of climatic conditions, whether it is cold winter or hot summer. Its insulation materials and outer protective layer are resistant to chemical corrosion, and can resist the erosion of chemical substances to a certain extent, ensuring the long-term stable operation of the cable. At the same time, YJLV cables usually have good flame retardant performance, which can slow down the spread of fire in the event of a fire and ensure the safety of personnel and equipment.



What is the YJLV cable model and application range?

YJLV: Aluminum core crosslinked polyvinyl chloride insulation polyvinyl chloride sheathed power cable. Fixed laying in indoor, tunnel and pipeline, cable can not withstand mechanical external force.

ZA(B, C, D) -YJLV: Aluminum core crosslinked PVC insulation PVC sheathed flame retardant A(B, C, D) Class O power cable.

YJLV 22: Aluminum core crosslinked polyvinyl chloride insulated polyvinyl chloride steel tape armored polyvinyl chloride sheathed power cable. Because it is laid indoors, in tunnels and in pipelines, the cable can withstand mechanical external forces.

ZA(B,C,D) -YJLV 22: Aluminum core crosslinked PVC insulated PVC steel tape armouring PVC sheathed flame retardant A(B,C,D) class power cable.

The above is about the YJLV aluminum core cable to explain, I believe that everyone has some understanding of it. Aluminum core cable repeated bending is easy to break, copper is not easy, elastic indicators, copper core is also 1.7 to 1.8 times higher than aluminum core. So it can't withstand external forces. Therefore, it is fixed in the indoor, tunnel and pipeline.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
