Owing to shifts in energy trends, the utilization of submarine three-core cross-linked polyethylene power cables has been on the rise, with capacities exceeding 66 kV. Recognizing the drawbacks associated with the use of J-tubes, there arose a demand for a new type of submarine cable system. This innovative system features a three-core submarine cable integrated with protective equipment, eliminating the need for J-tubes. In the new cable system, the choice of cable protection material becomes crucial, given its significant impact on material properties. the dispersion and solubility of graphene nanofiller were analyzed using different solvents (DMF, NMP, ethylene glycol, acetone, DI water) to ascertain its dispersion characteristics. Based on the dispersion results, it was observed that DMF and ethylene glycol exhibited the most effective dispersibility, while DI water displayed the least dispersibility.
