Imishini esetshenziselwa ukudlulisa ugesi phakathi kwamazwe noma izifunda ibizwa ngokuthi “imigqa exhunywe kugridi.” Njengoba umhlaba uphokophela emphakathini ongenawo umoya-mpilo, izizwe zigxile esikhathini esizayo, zizibophezele ekusunguleni amagridi kagesi aphesheya kwezilwandle naphakathi kwezifunda ahlanganiswe njengenethiwekhi ezindaweni ezinkulu ukuze kufezwe ukuxhumana kukagesi. Ngokuphambene nalezi zindlela zemakethe yamandla, iJapu Cables isanda kwenza amaphrojekthi amaningi ahilela ukukhiqizwa nokufakwa kwemigqa exhunywe kugridi kusetshenziswa izintambo ze-Direct Current XLPE.
Izinzuzo zezintambo zokudlulisa ze-DC zisekukwazini kwazo ukudlulisa amandla “ebanga elide” kanye “nomthamo ophezulu”. Ngaphezu kwalokho, uma kuqhathaniswa nezintambo ezifakwe uwoyela ezifakwe uwoyela, izintambo ze-DC XLPE ezifakwe i-polyethylene exhunywe nge-cross-linked zinobungani kakhulu nemvelo. Njengomholi kulo mkhakha, i-Japu Cables ihole imisebenzi emhlabeni jikelele, ifinyelela ukusebenza okuvamile kanye nokuguqulwa kwe-polarity kwe-voltage yokudlulisa emazingeni okushisa aphezulu omqhubi angu-90°C (20°C ephakeme kunezindinganiso zangaphambilini). Lokhu kuthuthuka kwenza ukudluliselwa kwamandla aphezulu futhi kwethula izintambo ezintsha ze-High Voltage Direct Current (HVDC) ezikwazi ukushintsha isiqondiso se-voltage (ukuguqulwa kwe-polarity nokushintsha isiqondiso se-transmission) ngokusekelwe ekusetshenzisweni kwemigqa exhunywe ngegridi ye-DC.
