Characteristics
1.Stable Electric Field Distribution: The electric field direction of a DC cable remains constant, eliminating the "skin effect" (current concentration on the conductor surface) found in AC cables. Current can be evenly distributed across the conductor cross-section, resulting in higher conductor utilization and a smaller conductor cross-sectional area for the same current carrying capacity.
2.Special Insulation Requirements: Under DC voltage, space charge easily accumulates within the insulation material, potentially leading to insulation aging and breakdown over long-term operation. Therefore, DC cables typically use insulation materials resistant to space charge accumulation, such as cross-linked polyethylene (XLPE), polyvinyl chloride (PVC), and rubber. Furthermore, the insulation layer thickness design must consider the withstand voltage characteristics of the DC electric field.
