YJLV cable is a commonly used power cable, widely used in power systems. The following is a basic introduction to the models, names, uses, features, risks, application scenarios and technical parameters of YJLV cables.

YJLV:

This is the model of the cable, where "Y" stands for polyethylene insulation, "J" stands for cross-linked polyethylene (XLPE) insulation, "L" stands for aluminum conductor, and "V" stands for polyvinyl chloride (PVC) sheath. Therefore, YJLV cables can be understood as power cables with cross-linked polyethylene insulation, aluminum conductors, and polyvinyl chloride sheaths.

USE：
YJLV cable is mainly used for fixed laying in the power system, as a transmission line of electric energy, suitable for industrial and mining enterprises, civil buildings, power stations and other places of power transmission and distribution.

Peculiarity:
Heat resistance: The crosslinked polyethylene insulation material has good heat resistance and can work stably at higher temperatures for a long time.
Aging resistance: The material used has good aging resistance, can resist the influence of ultraviolet light, ozone and other factors, and extend the service life.
Mechanical strength: Aluminum conductor has certain flexibility and mechanical strength, suitable for overhead or underground laying.
Fire retardant: Polyvinyl chloride sheath has a certain fire retardant effect, which can prevent the spread of flame to a certain extent.

Risk：
Electrical safety: If improperly installed or poorly maintained, it may lead to electrical safety accidents such as short circuit and leakage.
Environmental impact: PVC releases harmful gases when burned, posing a potential threat to the environment and human health.
Physical damage: The normal function of the cable may be affected if the cable is hit or cut by external forces..

Usage scenario：
It is widely used in many fields such as urban power grid, industrial distribution, and residential area power supply.

Technical parameter：
Rated voltage: common 0.6/1kV, 3.6/6kV, 6/10kV and so on.
Conductor cross-section: Select different conductor cross-sectional areas according to actual needs, such as 16mm², 25mm², 35mm², 50mm², etc.
Bending radius: The minimum bending radius of the cable is generally more than 10 times its outer diameter.
Temperature range: long-term operating temperature up to 90℃, short-term overload temperature up to 130℃.
Installation method: It can adopt a variety of installation methods such as direct burial, pipe row, bridge, etc.

Select the right cable type according to the actual requirements and environmental conditions, and install and maintain the cables in accordance with relevant standards and specifications.
