Copper vs. Aluminum Power Cables
1.Prioritize Copper Core (YJV) for:
Mission-Critical Installations: Hospitals, data centers, high-rise buildings, fire protection circuits.
Applications Requiring Flexibility: Dense cable tray routing, confined spaces, or any frequent movement.
High Long-Term Reliability Needs: Substations, key power distribution loops.
Smaller Cross-Sections (≤16mm²): Where aluminum’s mechanical disadvantages are most pronounced.
2.Prioritize Aluminum Core (YJLV) for:
Large-Section, Long-Distance Power Transmission: Medium-voltage distribution, overhead lines.
Budget-Sensitive, Large-Scale Projects: Industrial parks, municipal power distribution, non-critical loads.
Long-Span Installations: Where reducing weight on poles, towers, or trays is a primary concern.
Direct Burial or Outdoor Projects: Lightweight cables ease handling and reduce installation difficulty.
Low Voltage vs Medium Voltage vs High Voltage Cables: A Complete Guide
The classification is primarily based on rated operating voltage, though specific ranges can vary slightly by regional standards.
Low Voltage (LV) Cables: These are used for the distribution of lower power levels. The standard rated voltage is 1kV and below (common standards: 0.6/1kV). They are the workhorses of everyday electrical connectivity.
Medium Voltage (MV) Cables: These cables handle medium-level power distribution. The typical voltage range is from 3kV up to 35kV (with 8.7/15kV being an extremely common rating). Note: In everyday conversation, MV cables are sometimes mistakenly called “high voltage.”
High Voltage (HV) Cables: Designed for transmitting large amounts of power, HV cables operate from 35kV up to 110kV. Systems above this (e.g., 220kV and up) are typically categorized as Extra/Ultra High Voltage (EHV/UHV).

How Power Cables Are Built
A power cable is a marvel of engineering, composed of several integrated layers, each serving a distinct protective or conductive function.
Conductor (Core): Typically made of high-conductivity copper or lightweight aluminum, the conductor is the central pathway for electrical current.
Insulation Layer: This critical layer isolates the conductor from external contact, preventing current leakage or short circuits. Common materials include PVC (Polyvinyl Chloride) and XLPE (Cross-Linked Polyethylene), prized for their durability and high-temperature resistance.
Shield Layer (for MV/HV Cables): Primarily used in medium and high-voltage cables, this layer (often a metallic tape or semiconductive material) controls the electric field, reduces electromagnetic interference, and enhances safety.
Protective Sheath & Armor: The cable’s outer defense system.
Outer Sheath/Jacket: Provides protection against moisture, chemicals, abrasion, and environmental damage.
Armor (Steel Tape/Wire): Adds mechanical strength for crush and tensile resistance, essential for direct burial, duct, or tunnel installations.
In the intricate web of a subway system, safety is paramount. Every component, down to the cables that power and control the network, plays a crucial role. For metro rail applications, Low Smoke Halogen-Free (LZSH/LSZH) cables are not merely a superior choice—they are a non-negotiable, life-saving mandate dictated by stringent global fire safety codes.
