Product information "Electric cable"

Single core cable H07VK with seawater resistant PVC insulation according to VDE 0281 part 3. Rated voltage 450/750V. PVC self-extinguishing according to VDE0482-332-1-2, DIN EN 60332-1- 2/IEC 60332-1 (corresponds to DIN VDE 0472 part 804 test type B) Temperature range -40°C to +70°C. Copper, bare, finely stranded class 5 How is the optimum cable cross-section determined? To keep voltage loss and cable heating as low as possible, it is necessary to calculate the required cross-section. This requires the conductance of the copper (56) and the maximum permissible voltage loss. This is specified as 5% of the vehicle electrical system voltage for position lights (5% of 12V vehicle electrical system = 0.6V) or 7% for other consumers (7% of 12V vehicle electrical system = 0.84V). Formula: Cross-section = 2 x cable length x amperage (A) / 56 x voltage loss For a 25W / 12V position lamp with 12m cable length, the following equation results: 2 x cable length (12) x 2.1A (Watt / Volt) / 56 x 0.6V (5% on-board voltage).
