Izinto ezisetshenziselwa ukudlulisa ugesi phakathi kwamazwe noma izifunda zibizwa ngokuthi “imigqa exhunywe kwigridi.” Njengoba umhlaba uphokophele emphakathini ongasekho, izizwe zigxile ekusaseni, zizibophezele ekusunguleni amagridi kagesi aphesheya naphakathi kwezifunda axhumeke njengenethiwekhi ezindaweni eziningi ukuze kufinyelelwe ekuxhumekeni kukagesi. Ngokumelene nesizinda salezi zitayela zemakethe yamandla, i-Japu Cables isanda kwenza amaphrojekthi amaningi ahilela ukukhiqizwa nokufakwa kwezintambo ezixhunywe kugridi zisebenzisa izintambo ze-Direct Current XLPE.
Izinzuzo zezintambo zokudlulisa i-DC zisemandleni azo okudlulisa amandla "ibanga elide" kanye "nomthamo omkhulu". Ukwengeza, uma kuqhathaniswa nezintambo ezifakwe uwoyela ezifakwe uwoyela, izintambo ze-DC XLPE ezifakwe i-polyethylene exhunywe ngokuphambana zinobungani bemvelo. Njengomholi kulo mkhakha, i-Japu Cables isungule ukusebenza emhlabeni jikelele, ifinyelela ukusebenza okuvamile kanye nokuguqulwa kwe-polarity ku-voltage yokudlulisa emazingeni okushisa amakhondatha adlulele angu-90°C (20°C ngaphezu kwamazinga adlule). Le ntuthuko inika amandla ukudluliselwa kwamandla aphezulu futhi yethula izintambo ezintsha ze-High Voltage Direct Current (HVDC) ezikwazi ukushintsha indlela kagesi (ukuhlehla kwe-polarity kanye nokushintsha indlela yokudlulisa) ngokusekelwe ekusetshenzisweni kwemigqa exhunywe kugridi ye-DC.
