Tlhahlobo ea ts'ebetso ea lisebelisoa tsa Jacket ea cable
E le matla a bohlokoa le sesebelisoa sa phetisetso ea matšoao, the Cable e sebelisoa haholo le ho feta libakeng tse fapaneng tse feteletseng. Lits'ebetsong tse fapaneng, lisebelisoa tsa cable sheath li bapala karolo ea bohlokoa ho sireletseng likarolo tsa kahare tsa likhoele ho tsoa linthong tsa tikoloho joalo ka mongobo, mocheso le khatello ea mochini.
Pampiring ena, lisebelisoa tse robeli tse atisang ho sebelisoa cable sheathing - crosslinked polyethylene (XLPE), polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), perfluoroalkoxy resin (PFA), polyurethane (PUR), polyethylene (PE), thermoplastic polyethylene (TPE) vinylide mehlala e nkoa e le mehlala ea elastomer (TPE) vinyl. E mong le e mong o na le litšobotsi tse fapaneng tsa ts'ebetso, sepheo ke ho lekola ka botlalo ts'ebetso ea lisebelisoa tsena ka tlhahlobo e sebetsang le tlhahlobo ea data, le ho fana ka tataiso e sebetsang bakeng sa moralo le ts'ebeliso ea baki ea cable.
Lisebelisoa tsa Jacket:
Patlisiso ea ts'ebetso ea thepa le liteko tse sebetsang
1. Teko ea ho hanyetsa mocheso
Re entse liteko tsa ho hanyetsa mocheso lisebelisoa tse robeli, ho kenyeletsoa botsofali ba mocheso le liteko tsa tšusumetso e tlase ea mocheso.
Tlhahlobo ea lintlha:
| Lintho tse bonahalang | Mefuta e fapaneng ea mocheso oa botsofali ba mocheso (℃) | Thempereichara e amang mocheso o tlase (℃) |
XLPE | -40 ~ 90 | -60 |
PTFE | -200 ~ 260 | -200 |
FEP | -80 ~ 200 | -100 |

Ho tsoa ho data, ho ka bonoa hore PTFE, FEP, le PFA li na le ho monya ha metsi ka tlase le ts'ebetso e ntle ea thibelo ea mouoane oa metsi, e bonts'ang khanyetso e ntle ea metsi.
3. Tlhahlobo ea ho hanyetsa hlobo
Re ile ra etsa liteko tsa nako e telele tsa mokhoa oa hlobo ho shebella le ho tlaleha kholo ea hlobo holim'a thepa ka 'ngoe.
Tlhahlobo ea lintlha:
| Lintho tse bonahalang | Boemo ba ho hola ha hlobo |
XLPE | Kgolo e nyane |

Ho tsoa ho data, ho ka bonoa hore PTFE, FEP, le PFA li na le ts'ebetso e ntle ea anti hlobo libakeng tse mongobo.
4. Teko ea ts'ebetso ea motlakase
Lintho tsa motlakase tsa thepa, tse kang ho hanyetsa ho pata le matla a dielectric, li ile tsa lekoa.
Tlhahlobo ea lintlha:
Lintho tse bonahalang | Insulation resistance (Ω·m) | Matla a dielectric (kV/mm) |
XLPE | 10^14 | 30 |
PTFE | 10^18 | 60 |
FEP | 10^16 | 40 |

TSOELA | 10^11 | 20 |
TPE | 10^13 | 35 |
PVC | 10^10 | 15 |
Ho tsoa ho data, ho ka bonoa hore PTFE e na le khanyetso e phahameng ka ho fetesisa le matla a dielectric, a bonts'ang ts'ebetso e ntle ea motlakase. Leha ho le joalo, ts'ebetso ea motlakase ea PVC e batla e fokola.
5. Teko ea thepa ea mochini
Thepa ea mochini e joalo ka matla a tsitsipano le bolelele nakong ea khefu e ile ea lekoa.
Tlhahlobo ea lintlha:
Lintho tse bonahalang | Tensile matla (MPa) | Elongation nakong ea khefu (%) |
XLPE | 15-30 | 300-500 |
PTFE | 10-25 | 100-300 |
FEP | 15-25 | 200-400 |

Hangata lithapo li tlas'a ho kobeha, ho sotha, le mefuta e meng ea khatello ea mochine nakong ea ho kenya le ho sebetsa. Ho lekola matla a ho tsieleha, ho feto-fetoha ha maemo, le ho hanyetsa ha abrasion ea thepa ea baki ho bohlokoa ho bona bokhoni ba bona ba ho mamella likhatello tse joalo ntle le ho sekisetsa botšepehi ba mohala.
Ho ipapisitsoe le tlhahlobo ea data e kaholimo, ho khothaletsoa hore u khethe thepa e nepahetseng ea baki ea cable ho latela maemo le litlhoko tse ikhethang tsa ts'ebeliso:
Ho hanyetsa mocheso: PTFE le PFA li na le mocheso o pharalletseng ka ho fetesisa 'me li loketse haholo maemo a phahameng le a tlase a mocheso. Lisebelisoa tsena tse peli li loketse lits'ebetso tse hlokang mocheso o feteletseng.
Ho hanyetsa metsi: PTFE, FEP le PFA li na le ho monya metsi a tlase le thepa e ntle ea thibelo ea mouoane oa metsi, e bonts'ang khanyetso e ntle ea metsi. Lisebelisoa tsena li lokela ho nkoa bakeng sa likhoele tse sebelisoang libakeng tse metsi kapa tse ka tlas'a metsi.
Ho hanyetsa hlobo: PTFE, FEP le PFA li na le khanyetso e ntle ea hlobo libakeng tse mongobo. Lisebelisoa tsena li ratoa bakeng sa likhoele tse hlokang tšebeliso ea nako e telele libakeng tse nang le mongobo kapa hlobo.
Lintho tsa motlakase: PTFE e na le khanyetso e phahameng ka ho fetesisa le matla a dielectric, e bonts'ang thepa e ntle ea motlakase. Bakeng sa lits'ebetso tse hlokang ts'ebetso e phahameng ea motlakase, joalo ka lithapo tsa motlakase o phahameng kapa likhoele tsa phetiso ea matšoao, PTFE ke khetho e nepahetseng.
Lintho tsa mochini: PUR le TPE li sebetsa betere ka matla a tsitsitseng le bolelele nakong ea khefu, 'me li na le thepa e ntle ea mochini. Bakeng sa likhoele tse hlokang ho mamella khatello e kholo ea mochini kapa deformation, lisebelisoa tsena tse peli li ka nahanoa.
Ka kakaretso, tlhahlobo ea ts'ebetso eathapolisebelisoa tsa sheath li kenyelletsa tlhahlobo e felletseng ea ho hanyetsa ha bona lintho tsa tikoloho, ts'ebetso ea motlakase, matla a mochini, joalo-joalo Ka tlhahlobo e felletseng, bahlahisi le basebelisi ba ka etsa liqeto tse bohlale ho khetha thepa ea sheath ea cable e lumellanang hantle le litlhoko tsa bona tse ikhethang tsa kopo, qetellong ba ntlafatsa ts'epo le bophelo ba ts'ebeletso ea sistimi ea cable.
Khamphanie fana ka tšehetso e tiileng ea theory bakeng sa ho khothaletsa ntlafatso e felletseng ea ts'ebetso le nts'etsopele e tsitsitseng ea lisebelisoa tsa cable outer sheath. Ka nako e ts'oanang, ka nts'etsopele e tsoelang pele ea thekenoloji e ncha ea thepa le tlhokahalo e ntseng e eketseha ea kopo, re tla lebella ho fumana lisebelisoa tse phahameng tsa lisebelisoa tsa ka ntle tsa cable le uena, ho kenya matla a macha tsoelo-pele ea indasteri ea cable.
