Concentric cable is an advanced electrical cable designed for efficient power distribution, enhanced safety, and superior electromagnetic interference (EMI) shielding. It consists of a central conductor, surrounded by a concentric layer of neutral conductors and protective insulation, ensuring reliable and uninterrupted electricity flow.
Key Features of Concentric Cable
- High Conductivity: Uses copper or aluminum for optimal energy transmission.
- Electromagnetic Shielding: Reduces interference, ensuring stable performance.
- Robust Construction: Resistant to mechanical stress, UV exposure, and environmental factors.
- Enhanced Safety: Provides better fault protection and grounding.
- Flexible Installation: Suitable for underground, overhead, and residential applications.
Types of Concentric Cable
Concentric cables are classified based on their construction and voltage ratings.
| Type | Description | Typical Applications |
|---|---|---|
| Single-Core Concentric Cable | A single conductor with a surrounding neutral layer. | Power distribution, electrical meters. |
| Multi-Core Concentric Cable | Multiple conductors with a concentric neutral. | Industrial facilities, commercial buildings. |
| Low Voltage (LV) Concentric Cable | Rated for voltages up to 1kV. | Residential and street lighting networks. |
| Medium Voltage (MV) Concentric Cable | Rated between 1kV and 35kV. | Utility grids, substations. |
How Concentric Cable Works
Concentric cables function by transmitting electrical current through the central conductor while the surrounding concentric layer serves as a neutral and protective barrier. This configuration reduces power losses, enhances efficiency, and mitigates electrical hazards.
Main Components of Concentric Cable
- Central Conductor: Made of copper or aluminum for superior conductivity.
- Insulation Layer: Protects against short circuits and leakage.
- Concentric Neutral Conductors: Provide fault protection and EMI shielding.
- Outer Sheath: Ensures durability against environmental factors.
