High Voltage XLPE Power Cables (66kV – 500kV)
Engineered for High-Capacity Power Transmission Critical Infrastructure
TBEA High Voltage XLPE Power Cables are designed to deliver safe, stable, and efficient power transmission for modern electrical networks. Built using advanced cross-linked polyethylene (XLPE) insulation technology, these cables are suitable for long-distance, high-load transmission systems where reliability and performance are critical.
With a voltage range from 66kV to 500kV, these cables are extensively used in national grids, industrial power systems, transportation infrastructure, and large-scale energy projects worldwide.
Precision Manufacturing with Advanced Technology
Each High Voltage XLPE Cable is manufactured using Vertical Continuous Vulcanization (VCV) technology, ensuring uniform insulation thickness, excellent dielectric strength, and superior long-term stability.
Advanced production processes help reduce electrical losses, enhance thermal endurance, and maintain consistent performance even under continuous high voltage operation. These cables are engineered to operate reliably for a minimum service life of 30 years, making them a cost-effective solution for long-term infrastructure investments.
