I. Conductor
The "L" in YJLV indicates that the conductor is made of aluminum. Aluminum is chosen as the conductor material because it has certain cost advantages and its conductivity can meet the requirements of medium - voltage power transmission. In medium - voltage power - transmission application scenarios, the aluminum conductor can effectively conduct electric current. Although the resistivity of aluminum is slightly higher than that of copper, by rationally designing parameters such as the cross - sectional area of the conductor, efficient power transmission can still be achieved. For example, in some medium - voltage transmission lines that are cost - sensitive and of moderate distance, the use of aluminum conductors can reduce material costs while ensuring the basic requirements of power transmission.
II. Insulation
The "YJ" in YJLV stands for cross - linked polyethylene (XLPE). Cross - linked polyethylene is a high - quality insulating material widely used in cable manufacturing.
Electrical Properties
It has a high dielectric strength. This means that it can withstand a relatively high electric - field intensity without insulation breakdown, thus effectively isolating the conductor from the outside world, preventing current leakage into the surrounding environment, and ensuring the safe and stable transmission of electrical energy inside the cable.
In a medium - voltage environment, the insulating property of cross - linked polyethylene is particularly important. For example, in medium - voltage cables with a rated voltage of 6 kV - 35 kV, XLPE can stably maintain an insulated state. Even in cases of some over - voltage in the system, it can provide reliable insulation protection.
Thermal Properties
Cross - linked polyethylene has good thermal stability. During the operation of the cable, heat will be generated as the current passes through the conductor, and XLPE can keep its physical and chemical properties unchanged within a certain temperature range. It can withstand the working temperature during the normal operation of the cable and can also withstand a relatively high overload temperature for a short time without being damaged. For example, it can work continuously in a relatively high - temperature environment, and in the case of occasional temperature rises due to overload current, it can still maintain its insulating performance and ensure the normal operation of the cable.
III. Sheath
The "62" represents the type of sheath of this cable.
Protection Function
The outer sheath plays a crucial role in protecting the cable. It can protect the conductor and insulation layer inside the cable from mechanical damage, such as scratches and squeezes that may be encountered during cable laying. When the cable is laid underground, it can prevent hard objects such as stones underground from damaging the cable; when the cable is laid overhead, it can resist the impact of external objects.
The sheath can also prevent moisture from entering the cable. Once moisture enters the cable, it may damage the insulating performance of the insulation layer, causing leakage or even short - circuit faults. In addition, it can resist the influence of other environmental factors, such as chemical corrosion, ultraviolet radiation, etc. In some special environments, such as near chemical industrial parks or by the sea, the sheath can protect the cable from corrosive chemical gases or high - humidity, high - salinity air, extending the service life of the cable.
Material and Characteristics
The sheath material of the YJLV62 cable usually has a certain degree of flexibility and strength. The flexibility makes the sheath not easy to break during the bending and laying process of the cable, which is convenient for installation operations; the strength ensures that the sheath can remain intact when subjected to external pressure and tension. These characteristics make the YJLV62 cable suitable for multiple laying methods, such as direct - burial laying, pipe laying, overhead laying, etc., and can effectively protect the internal structure of the cable in different laying environments, ensuring the reliable operation of the cable in the medium - voltage power distribution system.
