The semi-conductive layers are a critical component in these cables. These layers are placed between the conductor and the XLPE insulation and between the insulation and the copper tape screen.
Their primary function is to reduce electric field stress, ensuring a smooth distribution of the electric field along the cable. Without these layers, high-stress points could form, leading to partial discharge, which could damage the cable over time.
Electric Field Management: Ensures that the electric field is distributed evenly, reducing the risk of damage from high-voltage surges.
Partial Discharge Prevention: Helps prevent partial discharge, which can degrade insulation over time.
Increased Longevity: By reducing stress within the cable, semi-conductive layers contribute to a longer cable lifespan.
The copper tape screen is an essential feature of these armored cables. It serves as an electromagnetic shield, helping to block any unwanted interference from external sources and providing additional protection from electrical faults.
Electromagnetic Shielding: The copper tape helps protect the cable from external electrical noise, ensuring stable performance.
Fault Containment: In case of an electrical fault, the copper tape screen contains the fault, preventing it from spreading and causing further damage to the system.
Improved Safety: By containing faults and reducing electromagnetic interference, the copper screen enhances the overall safety of electrical installations.
| Component | Function |
|---|---|
| Semi-Conductive Layer | Manages electric field stress and prevents discharge |
| Copper Tape Screen | Shields against electromagnetic interference, contains faults |
The use of XLPE (Cross-Linked Polyethylene) insulation in these cables ensures high performance in even the most demanding environments. XLPE insulated cables are ideal for high-voltage applications because they can handle elevated temperatures, offer great dielectric strength, and resist chemicals and moisture.
These properties are essential for ensuring a stable power supply in power stations, substations, and industrial installations.
Thermal Resistance: XLPE can withstand operating temperatures of up to 90°C, which is critical in high-load environments.
Excellent Electrical Properties: The dielectric strength of XLPE allows it to perform well under high voltage.
Durability: Resistant to chemicals, moisture, and mechanical stress, XLPE insulation ensures that the cable has a long operational life.
| Insulation Type | Temperature Rating | Dielectric Strength | Chemical Resistance | Longevity |
|---|---|---|---|---|
| PVC | Up to 70°C | Moderate | Moderate | 20-30 years |
| XLPE | Up to 90°C | High | High | 30-40 years |
For heavy-duty applications where cables are exposed to mechanical stress, SWA (Steel Wire Armoring) offers the necessary protection. This armoring is especially useful for cables that are installed underground or in other harsh environments.
The steel wire provides a layer of protection that prevents damage from impact or external forces, ensuring the cable’s longevity.
Mechanical Protection: Shields the cable from physical damage during installation and operation.
Increased Durability: Ideal for rugged environments such as underground cable runs, industrial areas, and submarine cable installations.
Longevity: Enhances the cable’s lifespan by protecting it from external forces.
| Armoring Type | Application | Protection Level | Flexibility | Cost |
|---|---|---|---|---|
| SWA | Underground, outdoor, industrial | High | Moderate | Moderate |
| Unarmored | Indoor installations | Low | High | Lower |
The versatility of Semi-Conductive Layers and Copper Tape Screen Armored Cables makes them ideal for a wide range of applications, particularly in environments where medium- to high-voltage electricity must be transmitted efficiently and safely.
Substations: These cables are commonly used to connect transformers and distribute power to various parts of the electrical grid.
Power Stations: Used in power generation facilities to transmit power at high voltages.
Underground Installations: Their armoring and insulation make them suitable for long underground runs, providing safe and efficient power distribution.
Industrial Facilities: These cables are used in industrial sites where large machines and heavy-duty equipment require a stable, high-voltage power supply.
| Application | Voltage Range | Benefits |
|---|---|---|
| Substations | 6.35/11KV | Reliable medium-voltage power distribution |
| Power Stations | 19/33KV | High-voltage transmission, durable under stress |
| Underground | 3.8/6.6KV | Armored for mechanical protection |
| Industrial Sites | 12.7/22KV | Oil, water, and chemical-resistant design |
One of the most common issues in high-voltage power cables is partial discharge, which can degrade the cable's insulation over time and lead to failures.
The semi-conductive layers in these cables work to manage the electric field stress, reducing the risk of partial discharge and extending the cable's lifespan.
Prevents Degradation: By controlling electric field stress, these layers minimize the risk of partial discharge.
Improved Safety: Reduced partial discharge means fewer insulation failures, which translates into safer operation.
Long-Term Reliability: Ensuring consistent performance over the cable's operational life.
| Risk Factor | Cause | Mitigation |
|---|---|---|
| Partial Discharge | High electric field stress | Semi-conductive layers reduce stress |
| Insulation Failure | Overvoltage, degradation | Copper tape screen contains faults |
In conclusion, Semi-Conductive Layers and Copper Tape Screen Armored Cables are the ideal solution for demanding electrical environments that require reliable, high-voltage power transmission. With their XLPE insulation, SWA armoring, and the critical addition of semi-conductive layers and a copper tape screen, these cables provide excellent protection, durability, and performance.
Whether you're working on a project for a substation, power station, or industrial site, these cables will ensure stable and efficient power distribution. Their ability to manage electric field stress, prevent partial discharge, and withstand mechanical damage makes them the top choice for modern electrical installations.
If you need a cable that delivers both performance and durability, the Semi-Conductive Layers and Copper Tape Screen Armored Cable is your best option for projects requiring up to 33kV.
