Our 66-500kV XLPE Insulated Power Cables offer a comprehensive range of designs to meet both technical specifications and economic requirements. They are suitable for use in diverse high-voltage transmission networks, offering flexibility in design and installation.
The key features of our cables include:
Extruded XLPE insulation: Offers excellent dielectric properties, high thermal stability, and resistance to aging.
Corrugated Aluminum Sheath: Provides enhanced mechanical protection and shielding against external damage.
Various Sheathing Options: Available with PVC or PE (Polyethylene) sheaths, ensuring protection against environmental factors such as moisture, UV exposure, and corrosion.
Water Resistance: Certain cable designs feature longitudinal water resistance (LWR) to prevent water ingress, making them ideal for installation in high-moisture environments.
The choice of conductor material is a critical factor in determining the overall efficiency and capacity of the power cable. We offer copper and aluminum conductors, each with its own set of advantages.
Copper Conductors: Known for their superior conductivity and reliability, copper conductors are ideal for high-performance applications where low resistive losses are critical. They are widely used in more demanding environments where performance is a top priority.
Aluminum Conductors: Lightweight and cost-effective, aluminum conductors are often selected for large-scale power transmission projects. They provide a lower cost alternative to copper while maintaining good electrical performance.
The conductor design can also be customized based on your needs, whether you require solid or stranded conductors for better flexibility and ease of installation.
The XLPE (Cross-Linked Polyethylene) insulation used in our high-voltage power cables is designed for exceptional electrical and mechanical properties, including:
High dielectric strength and electrical insulation resistance
Superior thermal stability, enabling the cables to operate in a wider range of temperatures
Resistance to aging and environmental stress
Our cables are equipped with either PVC or PE sheaths:
PVC Sheath: Provides excellent mechanical protection, flame retardancy, and resistance to UV radiation, making it suitable for outdoor and underground installations.
PE Sheath: Offers higher chemical resistance and durability, making it ideal for applications where the cable may be exposed to more aggressive environmental conditions.
Certain configurations also feature longitudinal water resistance (LWR), which provides an additional layer of protection against water ingress, making them suitable for use in wet or submerged environments.
Product features
