In modern power systems and industrial projects, MV-105 cables have become one of the most common and reliable medium-voltage cables in the North American market. With a rated operating temperature of 105°C, excellent electrical properties, and superior mechanical strength, they are widely used in distribution networks, substations, industrial parks, infrastructure projects, and large motor power supply systems.
This article will give you an in-depth overview of the structural features of MV-105 cables, the differences between single-core and multi-core designs, typical voltage ranges, and the choice between copper and aluminum conductors-helping you make the right selection at a glance.
Basic Structure of MV-105 Cables
Whether single-core or multi-core, the typical construction of an MV-105 cable includes:
Conductor: Copper (CU) or Aluminum (AL), available in compact round, stranded, or compressed forms
Insulation Layer: XLPE, TR-XLPE, or EPR, providing excellent heat and electrical resistance
Conductor Shield & Insulation Shield: Ensures uniform electric field distribution and enhances safety
Metallic Shield: Copper tape or copper wires to suppress electromagnetic interference
Outer Jacket: PVC, CPE, or LSZH, offering resistance to weathering and chemical corrosion
Single-Core MV-105 Cables
Single-core cables are the most common type of MV-105 cable, especially suitable for high-current transmission and trunk lines.
Typical Voltage Ratings: 5kV, 8kV, 15kV, 25kV, 35kV
Applications:
Substation feeder lines
Large industrial motor power supply
Main trunk distribution circuits
Advantages: High ampacity, flexible installation, and excellent heat dissipation
Multi-Core MV-105 Cables
Multi-core cables (commonly 2-core or 3-core) are designed for applications requiring multi-circuit power supply or compact installation.
Typical Voltage Ratings: 5kV, 8kV, 15kV, 25kV, 35kV
Applications:
Industrial distribution circuits
Motor and control equipment connections
Urban underground cable installations
Advantages: Space-saving, compact wiring, ideal for multi-load distribution

| 3/C CU 15kV MV-105 XLPE/CTS/PVC | 15kV | 3 cores | Copper | XLPE insulation + copper tape shield + PVC jacket | Industrial parks, distribution networks |
| 2/C AL 15kV MV-105 XLPE/CPE | 15kV | 2 cores | Aluminum | XLPE insulation + CPE jacket | Cost-effective distribution projects |
| 3/C CU 25kV MV-105 EPR/CTS/LSZH | 25kV | 3 cores | Copper | EPR insulation + copper tape shield + LSZH jacket | Underground cables, green engineering |
Voltage Ratings & Application Reference
| Voltage Rating | Typical Structures | Applications |
|---|---|---|
| 5kV / 8kV | Single-core, Multi-core | Industrial distribution, motor control |
| 15kV | Single-core, Multi-core | Most common engineering voltage, urban distribution & transmission |
| 25kV | Primarily single-core, some multi-core | High-voltage trunk lines, regional distribution |
| 35kV | Mainly single-core | High-voltage, large-capacity transmission |
Choosing Between Copper and Aluminum Conductors
Copper (CU)
Advantages: Excellent conductivity, strong flexibility, corrosion resistance
Best for: Space-limited or high-reliability projects
Aluminum (AL)
Advantages: Lightweight, cost-effective, easier installation
Best for: Large-scale distribution networks, long-distance transmission
