Insulated Overhead Cables Weaving a Greener Future

What are Insulated Overhead Cables?

Insulated overhead cables are overhead conductors that integrate an insulation layer and a protective sheath, manufactured using cross-linked cable technology. They combine the flexibility of overhead lines with the insulation properties of underground cables. Their core breakthroughs lie in:

  1. Structural Innovation:

The single-core design supports various conductor configurations, such as hard aluminum and steel-core reinforced, adapting to different voltage levels (1kV-35kV) and application scenarios.

2. Performance Leap:

Utilizing high-temperature resistant insulating materials like cross-linked polyethylene (XLPE), they achieve long-term tolerance at 90°C and short-circuit tolerance at 250°C, significantly reducing corona discharge losses and risks of damage from external forces.

3. Intelligent Adaptation:

The design incorporates outer and inner semi-conductive shielding layers to precisely control electric field distribution, extending service life to over 30 years.
