High Voltage Cables by RRH are built to handle 35-230kV, making them essential for long-distance energy transmission across power grids, between substations, and in large-scale infrastructure projects. These cables feature advanced insulation systems—often XLPE with semi-conductive layers—to prevent electrical breakdown under high stress, while their stranded conductors (aluminum or copper) minimize energy loss over miles. Designed for both overhead and underground use, they include weather-resistant jackets for outdoor installations and moisture barriers for underground trenches. RRH’s high voltage cables undergo rigorous testing for thermal cycling and short-circuit tolerance, ensuring reliability in extreme conditions. Ideal for connecting power plants to cities or interlinking regional grids, these cables balance efficiency and durability, playing a key role in maintaining stable electricity supply for millions.
