Kuongororwa kwekuita kwetambo Jacket zvinhu
Sesimba rakakosha uye chiratidzo chekutumira chishandiso, tambo iri kuwedzera uye zvakanyanya kushandiswa munzvimbo dzakasiyana dzakanyanyisa. Mumashandisirwo akasiyana-siyana, tambo sheath zvinhu zvinoita basa rakakosha mukuchengetedza zvemukati zvetambo kubva kune zvakatipoteredza zvinhu zvakaita sehunyoro, kupisa, uye kushushikana kwemagetsi.
Mupepa iri, zvisere zvinowanzoshandiswa tambo sheathing zvinhu - crosslinked polyethylene (XLPE), polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), perfluoroalkoxy resin (PFA), polyurethane (PUR), polyethylene (PE), thermoplastic elastomer (TPE) uye polyvinyl chloride (PVC) inotorwa semuenzaniso. Mumwe nemumwe ane maitiro akasiyana ekuita, chinangwa ndechekuongorora zvizere mashandiro ezvishandiso izvi kuburikidza nekuyedza kunoshanda uye kuongororwa kwedata, uye kupa nhungamiro inoshanda yekugadzira uye kushandiswa kwebhachi retambo.
Jacket Materials:
Tsvakurudzo yekushanda kwezvinhu uye kuedza kunoshanda
1. Temperature resistance test
Isu takaitisa tembiricha yekudzivirira bvunzo pazvinhu zvisere, zvinosanganisira kuchembera kwekushisa uye kuderera-tembiricha maitiro bvunzo.
Kuongorora data:
| Material | Tembiricha yemhando yekuchembera inopisa (℃) | Kuderera kwekushisa kunokanganisa tembiricha (℃) |
XLPE | -40~90 | -60 |
PTFE | -200~260 | -200 |
FEP | -80 ~ 200 | -100 |
PFA | -200~250 | -150 |
KUNYANGWE | -40~80 | -40 |
ON | -60~80 | -60 |
TPE | -60~100 | -40 |
PVC | -10~80 | -10 |
Sezvinoonekwa kubva mudhata, PTFE nePFA vane tembiricha yakakura kwazvo uye inonyanya kukodzera nzvimbo dzepamusoro uye dzakaderera tembiricha.
2. Muedzo wekudzivirira mvura
Takayedza zvinhu zvekuramba mvura, kusanganisira bvunzo dzekunyura uye bvunzo dzemvura vapor transmittance.
Kuongorora data:
Material | Mwero wekutora mvura (%) | Mvura vapor transmittance (g/m² · 24h) |
XLPE | 0.2 | 0.1 |
PTFE | 0.1 | 0.05 |
FEP | 0.1 | 0.08 |
PFA | 0.1 | 0.06 |
KUNYANGWE | 0.3 | 0.15 |
ON | 0.4 | 0.2 |
TPE | 0.5 | 0.25 |
PVC | 0.8 | 0.3 |
Kubva pane iyo data, zvinogona kuoneka kuti PTFE, FEP, uye PFA ine yakaderera mvura yekunyudza uye yakanakisa mvura vapor barrier performance, ichiratidza kumira zvakanaka kwemvura.
3. Mold resistance test
Isu takaita kwenguva yakareba mold tsika kuyedza kuti titarise uye tinyore kukura kwe mold pamusoro pechinhu chimwe nechimwe.
Kuongorora data:
| Material | Mold kukura mamiriro |
XLPE | Kukura zvishoma |
PTFE | Hapana kukura |
FEP | Hapana kukura |
PFA | Hapana kukura |
KUNYANGWE | Kukura zvishoma |
ON | Kukura zvishoma |
TPE | Kukura kuri pakati nepakati |
PVC | Kukura kunokosha |
Kubva pane data, zvinogona kuoneka kuti PTFE, FEP, uye PFA vane yakanakisa anti mold performance munzvimbo dzine hunyoro.
4. Muedzo wekushanda kwemagetsi
Zvinhu zvemagetsi zvezvinhu, zvakadai sekudzivirira kudzivirira uye simba re dielectric, zvakaedzwa.
Kuongorora data:
Material | Insulation kuramba (Ω·m) | Dielectric simba (kV/mm) |
XLPE | 10^14 | 30 |
PTFE | 10^18 | 60 |
FEP | 10^16 | 40 |
| PFA | 10^17 | 50 |
KUNYANGWE | 10^12 | 25 |
ON | 10^11 | 20 |
TPE | 10^13 | 35 |
PVC | 10^10 | 15 |
Kubva pane data, zvinogona kuoneka kuti PTFE ine yakanyanya kuvharidzira kuramba uye dielectric simba, ichiratidza kushanda kwemagetsi kwakanakisa. Zvisinei, kushanda kwemagetsi kwePVC kune zvishoma.
5. Mechanical property test
Iwo ma mechanic zvivakwa senge tensile simba uye elongation panguva yekuzorora akaedzwa.
Kuongorora data:
Material | Kusimba simba (MPa) | Elongation panguva yekuzorora (%) |
XLPE | 15-30 | 300-500 |
PTFE | 10-25 | 100-300 |
FEP | 15-25 | 200-400 |
PFA | 20-35 | 200-450 |
KUNYANGWE | 20-40 | 400-600 |
ON | 10-20 | 300-500 |
TPE | 10-30 | 300-600 |
PVC | 25-45 | 100-200 |
Cables dzinowanzo iswa pasi pekukotama, kumonyoroka, uye mamwe maitiro emagetsi kushushikana panguva yekuisa uye kushanda. Kuongorora kusimba kwesimba, kuchinjika, uye abrasion kuramba yejacket zvinhu zvakakosha pakuona kugona kwavo kutsungirira kushushikana kwakadaro pasina kukanganisa kutendeseka kwetambo. kureba panguva yekuzorora uye vane yakanaka michina zvivakwa, nepo PVC iine hurombo hwemagetsi zvivakwa.
Zvichienderana neongororo yedata iri pamusoro, zvinokurudzirwa kuti usarudze yakakodzera tambo jekete zvinhu zvinoenderana neaya chaiwo mamiriro ekushandisa uye zvinodiwa:
Tembiricha kuramba: PTFE nePFA vane tembiricha yakakura kwazvo uye inonyanya kukodzera kune yakakwirira uye yakaderera tembiricha nharaunda. Zvinhu zviviri izvi zvakanakira zvikumbiro zvinoda kupisa kwakanyanya.
Kuramba kwemvura: PTFE, FEP nePFA vane mvura yakaderera kunyura uye yakanakisa mvura mhute inodzivirira zvivakwa, inoratidza kumira zvakanaka kwemvura. Zvinhu izvi zvinofanirwa kutariswa kune tambo dzinoshandiswa munzvimbo dzakanyorova kana pasi pemvura.
Mold resistance: PTFE, FEP uye PFA vane yakanakisa mold kuramba munzvimbo dzine hunyoro. Zvishandiso izvi zvinosarudzirwa tambo dzinoda kushandiswa kwenguva refu munzvimbo dzine hunyoro kana ukuvhuvhu.
Electrical properties: PTFE ine yakanyanya kuvharidzira kuramba uye dielectric simba, inoratidza yakanakisa magetsi zvivakwa. Kune zvikumbiro zvinoda kushanda kwemagetsi epamusoro, senge tambo dzepamusoro-voltage kana tambo dzekutumira masaini, PTFE ndiyo sarudzo yakakodzera.
Mechanical properties: PUR uye TPE inoita zvirinani mukusimba kwesimba uye kureba panguva yekuzorora, uye iine yakanaka michina zvivakwa. Kune tambo dzinoda kumira zvakanyanya kushushikana kwemechani kana deformation, zvinhu zviviri izvi zvinogona kutariswa.
Pakazara, kuongororwa kwekuita kwecablesheath zvinhu zvinosanganisira kuongororwa kwakadzama kwekupokana kwavo kune zvakatipoteredza, kuita kwemagetsi, simba remagetsi, nezvimwe. Kuburikidza nekuongorora kwakadzama, vagadziri uye vashandisi vanogona kuita sarudzo dzakangwara dzekusarudza tambo sheath zvinhu zvinonyatsoenderana nezvinodiwa zvavo zvekushandisa, pakupedzisira vachivandudza iyo yakazara. kuvimbika uye hupenyu hwebasa retambo system.
The company inopa yakasimba theoretical rutsigiro rwekusimudzira yakazara mashandiro ekuvandudza uye kusimudzira kwakasimba kwetambo yekunze sheath zvinhu. Panguva imwecheteyo, nekuenderera mberi kwekuvandudza tekinoroji nyowani uye kuwedzera kwechikumbiro chekushandisa, isu tichatarisira kune yakawanda-inoshanda tambo yekunze sheath zvinhu newe, tichipinza hutsva hutsva mukufambira mberi kweindasitiri yetambo.
