Tight ... WebTherefore it is important to keep losses as low as practical. There are two sources of losses in the CICC – intrastrand losses and interstrand or cabling losses. The intrastrand losses are determined by the strand design, while the cabling pattern and the interstrand resistances determine the cabling losses.
