Izixhobo ezisetyenziselwa ukudlulisa umbane phakathi kwamazwe okanye imimandla zibizwa ngokuba “ziintambo ezidityaniswe negridi.” Njengoko ihlabathi lisiya kuluntu olungenakhabhoni, amazwe agxile kwikamva, ezizimisele ukuseka iigridi zamandla zamazwe ngamazwe kunye nezamazwe ngamazwe ezidityaniswe njengenethiwekhi kwiindawo ezinkulu ukuze kufezekiswe uqhagamshelo lombane. Ngokuchasene nale mizila yemarike yamandla, iJapu Cables isandula ukuqalisa iiprojekthi ezininzi ezibandakanya ukwenziwa nokufakwa kwemigca edityaniswe negridi kusetyenziswa iintambo zeDirect Current XLPE.
Iingenelo zeentambo zothumelo zeDC zikwikhono lazo lokuhambisa amandla “umgama omde” kunye “nomthamo ophezulu”. Ukongeza, xa kuthelekiswa neentambo zothumelo ezifakwe kwioyile, iintambo zeDC XLPE ezifakwe kwi-polyethylene edityanisiweyo zinobuhlobo ngakumbi nokusingqongileyo. Njengenkokeli kweli candelo, iJapu Cables iqalise ukusebenza kwihlabathi liphela, ifikelela ekusebenzeni okuqhelekileyo kunye nokuguqulwa kwe-polarity ye-transmission voltage kumaqondo obushushu aphezulu angama-90°C (20°C ngaphezulu kunemigangatho yangaphambili). Olu phuculo luvumela ukuhanjiswa kwamandla aphezulu kwaye luzisa iintambo ezintsha zeHigh Voltage Direct Current (HVDC) ezikwaziyo ukutshintsha ulwalathiso lwe-voltage (ukuguqulwa kwe-polarity kunye nokutshintsha ulwalathiso lwe-transmission) ngokusekelwe ekusetyenzisweni kwemigca eqhagamshelwe kwi-DC grid.
