During factory acceptance testing, partial discharge measurements verify that cable manufacturing processes have produced insulation systems free from voids, contamination, or workmanship defects that could lead to premature failure. During field commissioning after cable installation, partial discharge testing validates that termination and splicing work has been executed properly without introducing stress concentrations or gaps that would initiate discharge activity. Throughout service life, periodic partial discharge measurements enable condition-based maintenance programs that identify cables experiencing insulation deterioration before catastrophic failures occur, allowing planned replacements during scheduled outages rather than emergency repairs following unexpected breakdowns.

What are the acceptance criteria for Partial Discharge (PD) measurements on (N)TSCGEWÖU medium voltage cables (typically < 20 pC)?

NTSCGEWÖU mining cables manufactured according to DIN VDE 0250-813 specifications and operating at medium voltages ranging from six kilovolts to twelve kilovolts phase-to-phase, partial discharge testing serves multiple critical functions throughout the cable lifecycle. During factory acceptance testing, partial discharge measurements verify that cable manufacturing processes have produced insulation systems free from voids, contamination, or workmanship defects that could lead to premature failure.

Ozone resistance represents one of the most critical yet frequently overlooked material performance requirements for elastomeric power cables operating in demanding outdoor environments. This characteristic becomes particularly important for mining cables manufactured with rubber insulation and sheathing compounds, where exposure to atmospheric ozone can initiate premature degradation mechanisms that compromise both electrical performance and mechanical integrity. The DIN VDE 0472-805 standard, titled "Testing of cables, wires and flexible cords; Ozone resistance," establishes comprehensive test procedures for evaluating whether cable materials can withstand ozone exposure without developing the characteristic surface cracking that signals material breakdown.
