Use characteristics of medium voltage cable
The product is suitable for the AC rated voltage 35KV and below the power transmission and distribution. The maximum working temperature of the cable conductor is 90 degrees, short circuit (the longest time is not more than 5S), and the maximum temperature of the cable conductor is not more than 250 degrees.
The cause of the manufacturing of the cable body
Generally, in the process of cable production, the problems often occur in the process of cable production, such as insulation eccentricity, uneven thickness of insulation shielding thickness, impurities in insulation, penetration of internal and external shielding, uneven crosslinking degree, cable dampness, and poor sealing of cable metal sheath. It exists in the cable system in the form of defects, causing serious hidden danger to the cable's long-term and safe operation.
