I. Ịgba akaebe mgbanwe teknụzụ: Ka XLPE siri wepụrụ ihe ọdịnala
Na mbido 1990s, eriri PVC{1} nwere mkpuchi ka na-achịkwa. Mana ka a na-enyocha ọrụ na mpaghara ndịda China dị elu-okpomọkụ, oke- mpaghara iru mmiri, ahụrụ m ntụpọ ndị dị oke egwu: PVC na-eme ka ọ dị nro ma nwee nkwarụ n'oge ogologo oge- na-arụ ọrụ ogologo oge, na-enwe nnukwu ire ere ugbu a{{6}. Echiche m gbanwere n'oge mbụ XLPE medium{8}}voltage cable project (1998, 35kV nrụnye n'okpuru ala mepere emepe):
Ngosipụta ọnọdụ okpomọkụ: N'ezie okpomọkụ na-arụ ọrụ ruru ogo 90, 40% dị elu karịa PVC
Ekwenyere ikike ibufe ibu: guzogidere mkpirisi ogo 130 -okpomọkụ okirikiri na-agbaze
Ntụnyere Lifecycle: Ngwupụta ihe mgbe afọ 15 gachara egosighi oke osisi ịka nká na mkpuchi XLPE
Ahụmahụ ubi ndị a mere ka mkpebi 2005 anyị gbanwee n'ụzọ zuru ezu na ahịrị mmepụta XLPE. Taa, na ntọala Shaanxi Jinshenghong Cable, ahịrị CCV atọ (Continuous Curing Vulcanization) na-arụ ọrụ 24/7, ọkachamara na usoro mkpuchi mkpuchi XLPE dị elu{4}.
II. Teknụzụ na-emebi emebi: Nghọta ngwa XLPE dị mkpa

Ụdị Ọpụrụiche: Ọkụ -ọkụ na-eguzogide (950 degrees / 3h), eriri rodent/ụmụ ahụhụ, eriri EV
Usoro ike ọhụrụ: TUV 2PfG 1990 maka anyanwụ, DNV{2}}GL maka ikuku
V. Nkà na ụzụ Outlook: Afọ iri na-abịa
Data sitere na 100,{1} ọrụ ụlọ ọrụ na-ekpughe usoro atọ:
1. Smart Integration: DFOS (ikesa Fiber Optic Sensing) na State Grid pilot ọrụ na-enyere ezigbo oge -nleba anya okpomọkụ onye nduzi
