| No. | Layer | Key Materials/Requirements | Function |
|---|---|---|---|
| 1 | Conductor | Copper or Aluminum as ASTM Standard | Current-carrying core for power transmission |
| 2 | Conductor Shield (Inner Semi-conductive Layer) | Extruded semi-conductive material | Smooths the electric field at the conductor surface; prevents discharge at conductor-insulation interface |
| 3 | Insulation | TR-XLPE or EPR | Primary dielectric for voltage withstand; 90°C continuous (250°C short-circuit) |
| 4 | Insulation Shield (Outer Semi-conductive Layer) | Semi-conductive tape or extruded semi-conductive layer | Smooths the electric field on the outer surface of the insulation |
| 5 | Metallic Shield | Copper tape, Copper wire+copper tape, copper neutral wire, Longitudinally applied corrugated tape or Lead sheath | Carries fault current; provides electromagnetic shielding |
| 6 | Jacket | LLDPE, PVC, PP,HDPE,XLPE | Mechanical protection; weather and corrosion resistance |
| Insulation Level | Core Definition & Fault Clearing Time | Typical Application System | Relative Insulation Thickness |
|---|---|---|---|
| 100% Level | Fault cleared within 1 minute . Applicable where protection systems operate quickly and reliably. | Solidly Grounded Systems | Baseline (minimum thickness) |
| 133% Level | Fault clearing time exceeds 1 minute but does not exceed 1 hour . Applicable where faults cannot be cleared immediately but will eventually be isolated. | Impedance-Grounded Systems, or systems with delayed protection operation | Thicker than 100% level |
| 173% Level | Fault clearing time is not fixed; faults may persist for extended periods. Designed for the most severe applications, providing maximum insulation protection. | Ungrounded Systems, Resonant Grounded Systems | Thickest (highest dielectric stre |
| Jacket Material | Characteristics | Recommended Installation Environment |
|---|---|---|
| PVC (Polyvinyl Chloride) | General purpose, lower cost | Conventional indoor / outdoor |
| LLDPE (Linear Low-Density Polyethylene) | Excellent flexibility, UV resistance, and good crack resistance | Direct burial, outdoor exposure |
| HDPE (High-Density Polyethylene) | High hardness, high strength, excellent low-temperature impact resistance | direct burial or duct installation in cold regions |
| XLPE (Cross-linked Polyethylene) | Superior heat resistance | High temperature operating environments |
