At Jiangxi Zhongtebang Cable Co., Ltd., one of our key high-voltage cable products is the YJLHV82 cable, designed to meet the growing demands of modern power transmission and distribution networks. To help customers better understand its functionality and advantages, it is essential to first clarify the meaning behind its model designation and the structural design that defines its superior performance.

Meaning of the Model Designation

The name YJLHV82 cable is not arbitrary—it follows a systematic standard that reflects its material composition and design features:

• YJ: Stands for cross-linked polyethylene (XLPE) insulation. This insulation material provides excellent electrical performance, high thermal resistance, and long service life.

• L: Indicates the use of aluminum conductors, which are lightweight, cost-effective, and widely used in power transmission.

• HV: Refers to high-voltage application, showing that this cable is engineered to handle medium and high-voltage power distribution safely and reliably.

• 82: Represents the structural type, specifically steel tape armoring with PVC sheath. This construction ensures high mechanical strength, enhanced protection against external damage, and resistance to moisture and corrosion.

By analyzing its designation, users can immediately identify that the YJLHV82 cable is a robust solution for demanding environments where both electrical efficiency and mechanical durability are required.

Typical Structural Composition

The performance of the YJLHV82 cable is a direct result of its carefully engineered multi-layered structure:

1. Conductor – Made of high-quality aluminum strands, the conductor provides excellent conductivity while reducing overall cable weight compared to copper.

2. Insulation Layer – The cross-linked polyethylene insulation ensures superior dielectric properties, stable performance under high temperatures, and resistance to electrical breakdown.

3. Inner Sheath – This protective layer separates the insulation from the armor, ensuring mechanical integrity and additional safety.

4. Steel Tape Armoring – A layer of galvanized steel tape wraps around the inner sheath, providing outstanding protection against compression, impact, and other mechanical stresses during installation or operation.

5. Outer Sheath (PVC Jacket) – The polyvinyl chloride outer layer enhances resistance to moisture, chemicals, and environmental corrosion, making the cable suitable for underground, tunnel, or industrial applications.

This combination of layers ensures that the YJLHV82 cable not only delivers reliable electrical transmission but also withstands harsh installation conditions and long-term operational challenges.

The YJLHV82 cable offered by Jiangxi Zhongtebang Cable Co., Ltd. is a carefully engineered product that integrates advanced insulation technology, lightweight aluminum conductors, and strong protective armoring. Its definition and structure make it an ideal choice for power transmission projects that demand both performance and durability. By understanding its designation and internal design, customers can make informed decisions when selecting high-voltage cables for critical applications.
