YJV power cable is more suitable for low voltage power transportation

In high-voltage power systems, choosing the right cable is crucial. YJY cables and YJV cables, as common power cables, have attracted attention due to their excellent performance and wide range of applications. Zhengzhou Jinshui Industrial Co., Ltd. will analyze for you which cable is more suitable for high-voltage power systems from the definition, structure, performance, application, etc. of YJY cable and YJV power cable.

Overview of YJY power cable and YJV power cable

1.YJY cable

YJY cable, the full name of cross-linked polyethylene insulated PVC sheathed power cable, is a high-performance power cable. Its insulation layer is made of cross-linked polyethylene (XLPE) material, which has excellent electrical insulation properties, anti-aging properties and heat resistance. YJY cables are suitable for high-voltage power transmission and distribution systems and meet the requirements of modern power systems for high reliability, high efficiency and environmental protection.

2.YJV power cable

YJV cable, the full name is PVC insulated PVC sheathed power cable, is a common power cable. Its insulation layer and sheath layer are made of polyvinyl chloride (PVC) material, which has good electrical insulation performance and anti-interference ability. YJV cables are suitable for low-voltage power transmission and distribution systems, such as residential buildings, commercial buildings, factories and mines, etc.

Performance differences between YJY cable and YJV power cable

1. Electrical properties

YJY cable has superior electrical properties, with higher breakdown strength, lower dielectric loss and better aging resistance. In high-voltage power transmission situations, YJY cables have better performance. The electrical performance of YJV power cable is relatively low and is suitable for low-voltage transmission and distribution systems.

2.Mechanical properties

YJY cable has high tensile strength and can withstand large pulling force. But during the bending process, YJY cable is less flexible. The tensile strength of YJV cable is relatively low, but its bending performance is good, making it suitable for laying in complex environments.

3. Thermal performance

The insulation layer of YJY cable is made of cross-linked polyethylene (XLPE) material, which has good heat resistance. In high temperature environments, the performance of YJY cables deteriorates slowly. The insulation layer of YJV cable is made of polyvinyl chloride (PVC) material, which has relatively poor heat resistance.

Application occasions of YJY cable and YJV cable

YJY cable

YJY cable is suitable for high-voltage power transmission and distribution systems, such as power stations, substations, transmission lines, etc. In addition, YJY cables are also used in large engineering projects, petrochemical industries, nuclear power plants and other occasions with high reliability requirements.

YJV power cable

YJV cables are suitable for low-voltage power transmission and distribution systems, such as residential buildings, commercial buildings, factories and mines, etc. In addition, YJV cables are also used in power equipment, instrumentation, communication equipment and other fields.

Things to note when purchasing YJY cables and YJV cables

1. When purchasing, you should choose the appropriate cable specification, model and length according to actual needs.

2. Pay attention to the quality of the insulation layer and sheath layer of the cable to ensure that it has good voltage resistance, heat resistance and aging resistance.

3. Choose cables produced by regular manufacturers to ensure product quality and safety performance.

4. When purchasing, learn more about the installation, use and maintenance methods of cables from the sales staff.

YJY cables and YJV power cables have their own characteristics and are suitable for different applications. In high-voltage power systems, YJY cables are more suitable for high-voltage power transmission and distribution situations due to their excellent electrical properties, mechanical properties and thermal properties. However, in low-voltage power systems, YJV cables have good application prospects. When purchasing, you need to select the appropriate cable type based on actual needs and application situations.
