High and Extra High Voltage Cable Systems

Insulating power delivery through underground transmission cables

Power transmission utilities require years of reliable, consistent service for their customers. For both aging and new transmission infrastructure, including those that connect renewable energy sources like wind, solar, hydro and geothermal to the grid, high-quality HVAC and HVDC cables are paramount to the reliability and longevity to meet customer's demands.

At Dow, we ensure all of our underground transmission cable systems are made with quality materials– like ENDURANCE™ compounds for cable systems.   

Increased protection

Against external factors such as weather, vandalism, etc., resulting in greater reliability.

Lower visual impact

With no vegetation management versus overhead lines.

Easier installation

Smaller right of way and faster approval of applications for installation.

Lower emission

Of electromagnetic noise.

Maintenance costs

Lower short- and long-term maintenance costs than overhead lines.

Quality materials for quality cable systems

Along with advocating intelligent undergrounding, the concept for burying cable when and where it makes sense, we also believe that quality cables can only be derived from quality materials. We produce ENDURANCE™ compounds to the highest global performance standards – under the strictest quality control, handling, packaging and shipping guidelines.
