Introduction of power cable types for marine and offshore platforms

Yiziphi izintambo ezisetshenziswa emikhunjini nasezinkundleni zokuxhumana ezingasogwini?Okulandelayo yisingeniso sezinhlobo zezintambo zikagesi ezisetshenziswa emikhunjini nasezinkundleni zokuxhumana ezingasogwini.

1. Inhloso:

Lolu hlobo lwekhebula lufanele ukudluliswa kwamandla ezinhlelweni zikagesi ezine-voltage elinganiselwe ye-AC engu-0.6/1KV nangaphansi emikhunjini ehlukahlukene yomfula nolwandle, uwoyela wasolwandle nezinye izakhiwo zamanzi.

2. Izinga lesithenjwa:

I-IEC60092-353 1KV～3KV kanye nezintambo zamandla zasolwandle eziqinile ezinwetshiwe nezingaphansi

3. Sebenzisa izici:

Izinga lokushisa lokusebenza: 90 ℃, 125 ℃, njll.

I-voltage elinganiselwe i-U0/U: 0.6/1KV

Irediyasi yokugoba encane: hhayi ngaphansi kwezikhathi ezi-6 ububanzi bekhebula

Impilo yesevisi yekhebula ayikho ngaphansi kweminyaka engama-25.

4. Izinkomba zokusebenza:

Ukumelana kwe-DC komqhubi ku-20°C kuhlangabezana nezinga le-IEC60228 (GB3956).

Ukumelana nokwahlukanisa kwekhebula ku-20°C akukho ngaphansi kuka-5000MΩ·km (iphakeme kakhulu kunenkomba yokusebenza ye-insulation resistance resistance edingwa yi-IEC60092-353 standard).

Ukusebenza kwe-flame retardant kuhlangabezana nezimfuneko ze-IEC60332-3-22 Class A retardant (umlilo imizuzu engu-40, futhi ukuphakama kwe-carbonization yekhebula akweqi ku-2.5m).

Kuzintambo ezingashi, ukusebenza kwazo okungavimbeli umlilo kuhlangabezana ne-IEC60331 (imizuzu engu-90 (ukunikezwa komlilo) + imizuzu engu-15 (ngemuva kokususwa komlilo), izinga lokushisa lomlilo 750 ℃ (0 ~ +50 ℃) ukunikezwa kwamandla kwekhebula kuyinto evamile, akukho ugesi).

Inkomba yekhebula engenantuthu ephansi ye-halogen ihlangabezana nezidingo ze-IEC60754.2, ukukhishwa kwegesi ye-halogen acid akukho ngaphezu kwe-5mg/g, ukutholwa okuqondile kwenani layo le-pH akukho ngaphansi kuka-4.3, futhi ukuhanjiswa akukho ngaphezu kuka-10μs/mm.

Ukusebenza kwentuthu ephansi kwentambo: Ukuminyana kwentuthu (ukudlulisa ukukhanya) kwekhebula akukho ngaphansi kuka-60%.Hlangana nezidingo ezijwayelekile ze-IEC61034.

5. Isakhiwo sekhebula

Ikhondaktha yenziwe ngethusi elithayiwe lekhwalithi ephezulu.Lolu hlobo lwe-conductor lunomphumela omuhle kakhulu wokulwa nokugqwala.Isakhiwo se-conductor sihlukaniswe ama-conductor aqinile, ama-conductor axhunyiwe kanye nama-conductor athambile.

I-insulation ithatha i-extruded insulation.Le ndlela ye-extrusion inganciphisa igesi phakathi kwe-conductor kanye ne-insulation ukuvimbela ukungena kokungcola okufana nomhwamuko wamanzi.

Ikhodi yombala ngokuvamile ihlukaniswa ngombala.Imibala ingakhethwa futhi icutshungulwe ngokuya ngezidingo zesayithi ukuze kufakwe kalula.

I-sheath/liner yangaphakathi (Ijakhethi) iyintuthu ephansi engenayo i-halogen ene-flame retadancy ephezulu.Impahla ayinayo i-halogen.

Isendlalelo sezikhali (Armor) siwuhlobo olulukiwe.Lolu hlobo lwesivikelo lunokuguquguquka okungcono futhi lulungele ukubeka ikhebula.Izinto zempi ezilukiwe zibandakanya intambo yethusi ethayiwe kanye nensimbi yensimbi, kokubili okunomphumela omuhle wokunqanda ukugqwala.

Impahla yangaphandle (i-Sheath) nayo iyimpahla engenantuthu ephansi ye-halogen.Lokhu akukhiqizi igesi enobuthi lapho kusha futhi kukhiqiza intuthu encane.Isetshenziswa kakhulu ezindaweni eziminyene.

Ukuhlonza ikhebula kungaphrintwa ngokwezidingo zangempela.

6. Imodeli yekhebula:

1. I-XLPE ifake imodeli yekhebula engaphandle ene-halogen engenantuthu ephansi:

CJEW/SC, CJEW/NC, CJEW95(85)/SC, CJEW95(85)/NC,

2. I-EPR igqume imodeli yekhebula engaphandle ene-halogen engenantuthu ephansi:

CEEW/SC, CEEW/NC, CEEW95(85)/SC, CEEW95(85)/NC,

3. Incazelo yemodeli:

C- kusho ikhebula lamandla olwandle

Ukufakwa kwe-J-XLPE

I-E-EPR (Ethylene Propylene Rubber Insulation)

EW-low intuthu halogen free polyolefin emgodleni

95- Izikhali ezilukwe ngocingo lwensimbi oluyinsimbi kanye nomgodla wangaphandle we-LSZH (umluko ongekho ngaphansi kwama-84%)
