Izixhobo ezisetyenziselwa ukuhambisa umbane phakathi kwamazwe okanye imimandla kubhekiselwa kuzo “njengeentambo eziqhagamshelwe kwigridi.” Njengoko ihlabathi lisingise kuluntu oluphelelwa yikhabhoni, izizwe zigxile kwikamva, zizibophelele ekusekeni iigridi zamandla eziphuma kumazwe ngamazwe naphakathi kwemimandla ezidityaniswe njengothungelwano kwiindawo ezininzi ukuphumeza uqhagamshelo lombane. Ngokuchasene nemvelaphi yale mizila yemarike yamandla, iJapu Cables isandula ukwenza iiprojekthi ezininzi ezibandakanya ukwenziwa kunye nokufakelwa kweentambo eziqhagamshelwe kwigridi kusetyenziswa iintambo eziNgqo kwangoku zeXLPE.
Izibonelelo zeentambo zothumelo lwe-DC zilele kwisakhono sazo "somgama omde" kunye "nomthamo ophezulu" wokuhambisa amandla. Ukongeza, xa kuthelekiswa neentambo ezifakwe kwi-oyile ezifakwe kwi-oyile, iintambo ze-DC XLPE ezifakwe kwi-polyethylene edibeneyo zihambelana nokusingqongileyo. Njengenkokeli kulo mmandla, iiCables zeJapu zisebenze njengovulindlela kwihlabathi jikelele, zifezekisa ukusebenza okuqhelekileyo kunye nokuguqulwa kwe-polarity yombane wothumelo kumaqondo obushushu obuchwephesha obungama-90 ° C (20 ° C ngaphezulu kwemigangatho yangaphambili). Olu phuculo luvumela ukuhanjiswa kwamandla omthamo ophezulu kwaye lwazisa iintambo ze-High Voltage Direct Direct Current (HVDC) ezikwaziyo ukutshintsha icala lamandla ombane (ukuguqulwa kwepolarity kunye nokutshintsha indlela yothumelo) ngokusekelwe ekusetyenzisweni kweentambo zegridi ze-DC eziqhagamshelwe.
