The (N)TSCGEWÖU cable, designed specifically for demanding reeling and unreeling operations in mining and heavy industry, must demonstrate exceptional flex endurance to ensure reliable power transmission throughout its service life. This technical document examines how the standardized two-pulley flexing test according to BS EN 50396 and IEC 60245 standards accurately simulates real-world cable life cycles and validates the mechanical durability of these critical power transmission components.

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.
