Gịnị bụ ihe nke Electircal waya shield?

Ọ gụnyere polyethylene, polyethylene cross-linked, polyvinyl chloride, polypropylene, polyolefin, fluoroplastics, naịlọn, wdg.
Polyethylene bụ ihe a na-ejikarị eme ihe na plastik ugbu a.Site na data dị na tebụl, a pụrụ ịhụ na polyethylene nwere obere mfu muon, nnukwu resistivity, ike nkwụsị nke ubi, ezigbo nkwụsị ihu igwe na nhazi nhazi.Ihe mkpuchi mkpuchi.Agbanyeghị, n'ihi ọnọdụ okpomọkụ ya dị ala, a na-ejikarị ya dị ka ihe mkpuchi maka eriri nkwukọrịta.Ọkara njupụta na nnukwu njupụta polyethylene nwere ike dị elu na ike siri ike, na ike mmiri ha dị ala, a na-ejikarị ha eme ihe dị ka jaket USB.Otú ọ dị, polyethylene nwere nnukwu mwepu, ya bụ, ọ dị mfe ọkụ ma nwee nnukwu anwụrụ ọkụ ojii, ya mere ngwa ya na-eweta ọtụtụ ihe egwu zoro ezo na gburugburu ebe obibi.
Polyethylene jikọtara cross bụ ezigbo ihe mkpuchi ọkụ na-emepụta site n'ịgbakwụnye ihe na-ejikọta ya na polyethylene dị obere.Na ndabere nke iketa ọtụtụ ndị magburu onwe Njirimara nke polyethylene, ọ mma n'ibu Njirimara, ihu igwe na-eguzogide na ekwe na-arụ ọrụ okpomọkụ, si otú na-aghọ ndị kasị mma mkpuchi ihe maka ike cables ugbu a.
A na-emepụta usoro njikọ dị iche iche n'ihi ihe dị iche iche na-ejikọta ọnụ.Njikọ kemịkalụ atọ a na-ejikarị eme ihe, njikọta mmiri ọkụ, yana njikọ radieshon.Kemịkalụ cross-linking bụ tumadi eji maka ọkara na elu voltaji cables (dị ka 10KV na n'elu);A na-ejikarị eriri mmiri na-ekpo ọkụ na-ejikọta na njikọ irradiation maka eriri obere voltaji (1kV na n'okpuru).
Njirimara mkpuchi nke polyethylene na-ejikọta ya na njikọ chiri anya na ịdị ọcha ya.The mkpuchi nke elu voltaji na ultra-elu-voltage cables n'elu 35KV ga-eji ultra-dị ọcha cross-njikọ polyethylene, nke ọ bụghị nanị na-achọ elu ịdị ọcha nke akụrụngwa, ma na-achọkwa elu ịdị ọcha nke cross-njikọ usoro akụrụngwa na gburugburu ebe obibi, na usoro kwụsiri ike na ntụkwasị obi.
Ekwesịrị ịkọwapụta nke ọma na ihe mkpuchi mkpuchi nke polyethylene na polyethylene cross-linked nwere "quirk", ya bụ, ha dị mma maka mkpuchi AC, ma ọ bụghị maka mkpuchi DC, karịsịa DC voltaji dị elu ga-ebelata ndụ mkpuchi ha.Ya mere, mkpuchi nke eriri DC na-abụkarị ihe mkpuchi rọba ma ọ bụ mkpuchi mmanụ-akwụkwọ.Ọzọkwa, polyethylene na cross-linked polyethylene mkpuchi nwere "hydrophobia", na mmebi ya na-ejikọtakarị na ọnụnọ mmiri, ya bụ, nhazi nke "alaka mmiri" n'okpuru nnukwu voltaji, na-akpata mmebi mkpuchi.Ya mere, mgbe a na-eji polyethylene na cross-linked polyethylene eme ihe maka mkpuchi nke eriri eletrik na ultra-high-voltage, ha na-abụkarị "mmiri na-eguzogide" n'oge nhazi ha, nchekwa na njem na mkpuchi mkpuchi, na mkpuchi mkpuchi eriri USB. kwesịrị inwe usoro mgbochi mmiri, dị ka jaket ígwè.
