Scenario: A cable buried in thick thermal insulation might have its capacity slashed in half (factor of ). The "Magic" of the Calculation

In some standards, grouping nine cables together can reduce the individual capacity of each cable by 50%. 3. Depth of Laying ( Kdepthcap K sub d e p t h end-sub derating factor of cable

Not all dirt is created equal. Dry, sandy soil is a poor heat conductor compared to moist, compacted clay. If the soil cannot pull heat away from the cable quickly, the cable must be derated to compensate for the "thermal bottleneck." 5.
