High Voltage Cables: Unleash Uninterrupted Power for Critical Infrastructure
Product Overview
High Voltage (HV) Cables are the indispensable backbone of modern electrical grids, designed to efficiently and reliably transmit electrical energy at voltages typically ranging from 69 kV up to 500 kV and beyond. Engineered for superior performance in demanding environments, our HV cables ensure the secure and continuous flow of power over long distances, connecting generation sources to load centers, and supporting the robust infrastructure required by utilities, industrial complexes, and renewable energy projects worldwide.
Our premium HV cables are meticulously manufactured using state-of-the-art materials and advanced production techniques, ensuring unparalleled reliability, minimal energy losses, and an extended operational lifespan.
Key Features
Robust Conductor Materials:
Available in high-purity, compacted, and stranded Copper (Cu) or Aluminum (Al) conductors.
Designed for maximum conductivity, excellent current-carrying capacity, and reduced resistance losses.
Offers superior dielectric strength, thermal stability, low dielectric loss, and excellent resistance to water treeing.
Precision Extruded Semi-Conducting Shields:
Both conductor shield and insulation shield layers are precisely extruded over and under the insulation.
Ensures uniform electric field distribution, prevents partial discharges, and enhances long-term insulation integrity.
Integrated Metallic Screen/Sheath:
Comprising copper wire screens, copper tape shields, corrugated aluminum, or lead alloy sheaths.
Provides a safe ground return path, contains the electric field, mitigates electromagnetic interference (EMI), and offers radial water blocking.
Durable Outer Jacket:
Constructed from robust materials such as MDPE (Medium-Density Polyethylene), HDPE (High-Density Polyethylene), PVC (Polyvinyl Chloride), or LSZH (Low Smoke Zero Halogen) compounds.
Offers superior resistance to abrasion, moisture ingress, UV radiation, chemicals, and mechanical impact. LSZH options ensure enhanced fire safety in sensitive areas.
Water Blocking Technology:
Incorporates longitudinal and radial water blocking elements (e.g., swellable tapes, semi-conductive compounds) to prevent water ingress and migration along the cable, crucial for underground and submarine installations.
Optional Armoring:
Available with galvanized steel wire armoring (GSWA) or steel tape armoring (STA) for enhanced mechanical protection in direct burial, submarine, or rugged industrial applications.
Customizable Designs:
Offered in various conductor sizes, voltage ratings, core configurations, and construction types to meet specific project requirements and international standards.
Benefits
Exceptional Reliability: Engineered for long-term, stable operation, significantly reducing downtime and ensuring continuous power supply.
High Transmission Efficiency: Minimized power losses due to advanced conductor and insulation materials, leading to lower operating costs and a reduced carbon footprint.
Extended Lifespan: Constructed with high-quality, durable materials that resist aging, environmental degradation, and electrical stress, providing decades of maintenance-free service.
