The field of underground power transmission is constantly evolving, driven by the need for higher capacity, improved efficiency, and enhanced reliability. Some of the most significant advancements include:

• Cross-Linked Polyethylene (XLPE) Cables: XLPE is now the industry standard for solid dielectric insulation, replacing older fluid-filled systems. These cables are more reliable, require less maintenance, and are easier to install.

• High-Voltage Direct Current (HVDC) Cables: HVDC technology is gaining traction for long-distance underground transmission. It offers a significant advantage over AC lines by eliminating charging current issues, which limit the length of AC underground cables, and by reducing energy loss.

• High-Temperature Superconducting (HTS) Cables: Although still a developing technology, HTS cables have the potential to carry far more power than conventional cables with virtually no energy loss, all within a smaller footprint.

• Integrated Monitoring Systems: Modern cables are being integrated with fiber optic sensors and other monitoring technologies to provide real-time data on temperature, pressure, and potential faults. This allows for proactive maintenance and quicker fault location, mitigating one of the key disadvantages of underground systems.

At Ningbo Changshi, we are committed to providing the tools and equipment needed to handle these next-generation technologies. Our products are designed to support the specialized installation and maintenance requirements of today's most advanced underground cable laying projects.
