Lithapo tse phahameng tsa motlakase bakeng sa likoloi tsa motlakase li na le litlhoko tse phahameng tsa ts'ebetso likarolong tsohle, 'me li lokela ho kopana le maemo a RoHSb, litlhoko tse tloaelehileng tsa lelakabe la UL94V-0 le ts'ebetso e bonolo. Pampiri ena e hlahisa lisebelisoa le theknoloji ea ho lokisa ea lithapo tse phahameng tsa motlakase bakeng sa likoloi tsa motlakase.
1.Thepa ea thapo e phahameng ea motlakase
(1) Lisebelisoa tsa conductor tsa thapo
Hona joale, ho na le lisebelisoa tse peli tse ka sehloohong tsa cable conductor layer: koporo le aluminium. Lik'hamphani tse 'maloa li nahana hore aluminium ea mantlha e ka fokotsa litšenyehelo tsa tlhahiso ea tsona haholo, ka ho eketsa koporo, tšepe, magnesium, silicon le likarolo tse ling motheong oa lisebelisoa tse hloekileng tsa aluminium, ka mekhoa e khethehileng e kang synthesis le kalafo ea annealing, ho ntlafatsa conductivity ea motlakase, ts'ebetso ea ho khumama le ho hanyetsa kutu ea thapo, e le ho finyella litlhoko tsa matla a tšoanang le a koporo, ho finyella liphello tse ntle tse tšoanang le tsa koporo. Ka hona, litšenyehelo tsa tlhahiso li bolokiloe haholo. Leha ho le joalo, likhoebo tse ngata li ntse li nka koporo e le thepa e ka sehloohong ea lera la mokhanni, pele ho tsohle, ho hanyetsa ha koporo ho tlaase, 'me joale boholo ba ts'ebetso ea koporo e molemo ho feta ea aluminium e boemong bo tšoanang, joalo ka matla a maholo a ho jara hona joale, tahlehelo e tlaase ea motlakase, tšebeliso e tlaase ea matla le ho tšepahala ho matla. Hona joale, khetho ea li-conductor ka kakaretso e sebelisa li-conductors tse bonolo tsa naha tse 6 (elong e le 'ngoe ea terata ea koporo e lokela ho ba kholo ho feta 25%, bophara ba monofilament bo ka tlaase ho 0,30) ho netefatsa hore bonolo le ho tiea ha monofilament ea koporo. Lethathamo la 1 le thathamisa litekanyetso tse lokelang ho finyelloa bakeng sa lisebelisoa tse sebelisoang hangata tsa koporo.
(2) Lisebelisoa tsa lera la insulate tsa likhoele
Tikoloho e ka hare ea likoloi tsa motlakase e rarahane, ha ho khethoa thepa ea ho sireletsa, ka lehlakoreng le leng, ho netefatsa tšebeliso e sireletsehileng ea lera la ho pata, ka lehlakoreng le leng, ka hohle kamoo ho ka khonehang ho khetha lisebelisoa tse bonolo le tse sebelisoang haholo. Hajoale, lisebelisoa tse sebelisoang hangata ke polyvinyl chloride (PVC).polyethylene e kopantsoeng ka sefapano (XLPE), rabara ea silicone, thermoplastic elastomer (TPE), joalo-joalo, 'me thepa ea bona e ka sehloohong e bontšoa ho Lethathamo la 2.
Har'a tsona, PVC e na le loto, empa Tataiso ea RoHS e thibela tšebeliso ea lead, mercury, cadmium, hexvalent chromium, polybrominated diphenyl ethers (PBDE) le polybrominated biphenyls (PBB) le lintho tse ling tse kotsi, kahoo lilemong tsa morao tjena PVC e nkeloe sebaka ke XLPE, lisebelisoa tse ling tsa rabara le silicone.
(3) Lisebelisoa tsa lera la tšireletso ea cable
The shielding layer e arotsoe ka likarolo tse peli: semi-conductive shielding layer le braided shielding layer. Bophahamo resistivity ya semi-conductive shielding lintho tse bonahalang ka 20 ° C le 90 ° C 'me ka mor'a botsofali ke index bohlokoa botekgeniki ho lekanya lintho tse sireletsang, e leng ka tsela e sa tobang etsa qeto ea bophelo ba tšebeletso ea kabel phahameng-voltage. Lisebelisoa tse tloaelehileng tsa semi-conductive shielding li kenyelletsa rabara ea ethylene-propylene (EPR), polyvinyl chloride (PVC), lepolyethylene (PE)thepa e thehiloeng. Tabeng ea hore thepa e tala ha e na molemo 'me boemo ba boleng bo ke ke ba ntlafatsoa ka nako e khutšoanyane, mekhatlo ea lipatlisiso tsa saense le bahlahisi ba lisebelisoa tsa cable ba shebane le lipatlisiso tsa thekenoloji ea ho sebetsa le tekanyo ea foromo ea thepa e sireletsang,' me ba batla mekhoa e mecha ka tekanyo ea sebopeho sa thepa e sireletsang ho ntlafatsa tshebetso ea kakaretso ea mohala.
2.Ts'ebetso ea ho lokisa cable e phahameng ea motlakase
(1) Theknoloji ea li-conductor strand
Ts'ebetso ea mantlha ea cable e entsoe ka nako e telele, ka hona ho boetse ho na le litlhaloso tsa bona tse tloaelehileng indastering le likhoebong. Ts'ebetsong ea ho taka terata, ho latela mokhoa o sa sisinyeheng oa terata e le 'ngoe, lisebelisoa tsa stranding li ka aroloa ka mochine o sa tsitsang oa mochine, mochine o sa tsitsang le mochine o sa tsitsang / o sa tsitsang. Ka lebaka la mocheso o phahameng oa kristallise oa mokhanni oa koporo, mocheso le nako e telele, ho loketse ho sebelisa lisebelisoa tsa mochini tse sa sothoeng ho etsa ho hula ho tsoelang pele le ho hula monwire ho ntlafatsa bolelele le sekhahla sa ho robeha ha terata. Hajoale, thapo ea polyethylene e hokahantsoeng ka sefapano (XLPE) e nkile sebaka ka botlalo thapo ea pampiri ea oli lipakeng tsa 1 le 500kV voltage level. Ho na le mekhoa e 'meli e tloaelehileng ea ho etsa li-conductor bakeng sa li-conductor tsa XLPE: compaction e chitja le ho sotha terata. Ka lehlakoreng le leng, mokokotlo oa terata o ka qoba mocheso o phahameng le khatello e phahameng ea phaephe e amanang le sefapano ho hatella thepa ea eona e sireletsang le thepa ea ho itšireletsa ka har'a lekhalo la terata e ts'oaretsoeng le ho baka litšila; Ka lehlakoreng le leng, e ka boela ea thibela ho kenella ha metsi ho latela tataiso ea conductor ho netefatsa ts'ebetso e sireletsehileng ea mohala. Conductor ea koporo ka boeona ke mohaho o tsitsitseng, o hlahisoang haholo ke mochine o tloaelehileng oa foreimi, mochine oa fereko oa fereko, joalo-joalo Ha o bapisoa le ts'ebetso e chitja ea compaction, e ka etsa bonnete ba hore mokhanni o pota-potile sebopeho se pota-potileng.
(2) Ts'ebetso ea tlhahiso ea li-cable tsa XLPE
Bakeng sa tlhahiso ea thapo e phahameng ea XLPE, catenary dry cross-linking (CCV) le vertical dry cross-linking (VCV) ke mekhoa e 'meli ea ho theha.
(3) Ts'ebetso ea Extrusion
Pejana, baetsi ba lithapo ba ne ba sebelisa mokhoa oa bobeli oa extrusion ho hlahisa konokono ea li-cable insulation, mohato oa pele ka nako e ts'oanang thebe ea conductor ea extrusion le lera la ho kenya letsoho, ebe e hokahanngoa le leqeba ho terei ea mohala, e behiloe nako e telele ebe thebe ea extrusion insulation. Nakong ea lilemo tsa bo-1970, ts'ebetso ea 1 + 2 ea mekhahlelo e meraro e ile ea hlaha mokokotlong oa terata e sirelelitsoeng, e lumellang tšireletso ea ka hare le ea ka ntle ho phethoa ka mokhoa o le mong. Ts'ebetso e qala ka ho ntša thebe ea conductor, ka mor'a sebaka se sekhutšoanyane (2 ~ 5m), ebe e ntša tšireletso le tšireletso ea tšireletso holim'a thebe ea conductor ka nako e le 'ngoe. Leha ho le joalo, mekhoa e 'meli ea pele e na le litšitiso tse kholo, kahoo ho elella bofelong ba lilemo tsa bo-1990, bafani ba thepa ea tlhahiso ea lithapo ba ile ba hlahisa mokhoa oa tlhahiso ea li-co-extrusion tse tharo, tse ileng tsa hlahisa tšireletso ea conductor, ho pata le ho sireletsa ka nako e le' ngoe. Lilemong tse 'maloa tse fetileng, linaha tsa linaha tse ling li ile tsa boela tsa hlahisa hlooho e ncha ea extruder barrel le moralo o kobehileng oa poleiti, ka ho leka-lekanya "screw head cavity" khatello ea phallo ho fokotsa ho bokella lintho tse bonahalang, ho lelefatsa nako e tsoelang pele ea tlhahiso, ho nkela sebaka sa phetoho e sa khaotseng ea litlhaloso tsa moralo oa hlooho e ka boela ea boloka litšenyehelo tsa ho theoha le ho ntlafatsa katleho.
