Recently, many customers have asked about the maintenance of high-voltage cables. When using high-voltage cables, there may be some problems. The common problems in the production process of cable are insulation eccentricity, uneven thickness of insulation shield, impurities in insulation, protrusion of internal and external shielding, uneven degree of crosslinking, damp of cable, poor sealing of cable metal sheath, etc.
Some cases are relatively serious, which may occur in the completion test or shortly after the commissioning, and most of them exist in the form of defects in the cable system, causing serious hidden danger to the long-term safe operation of the cable.
