Cov yam ntxwv thiab kev siv ntawm cov fais fab cables

Cov yam ntxwv tseem ceeb:

1. Lub sij hawm ntev tso cai ua hauj lwm kub ntawm cable conductor yuav tsum tsis txhob ntau tshaj 70 ℃. Nyob rau hauv cov ntaub ntawv ntawm luv luv Circuit Court (zoo dua yuav kav tsis tshaj 5 vib nas this), qhov siab tshaj plaws kub ntawm cable conductor yuav tsum tsis txhob ntau tshaj 160 degrees.

2. Qhov kub thiab txias thaum lub sij hawm tso cable yuav tsum tsis txhob qis dua 0 ° C. yog tias nws qis dua 0 ° C, nws yuav tsum tau preheated ua ntej. Qhov tsawg kawg nkaus dabtsi yog khoov vojvoog yuav tsum tsis txhob tsawg tshaj li sab nraud txoj kab uas hla. Ib leeg tub ntxhais cable yuav tsum yog 20 zaug tsis muaj armor thiab 15 zaug nrog armor. Peb core cable yog 15 zaug armored thiab 12 zaug armored.

3. Lub DC cathode ntawm tus neeg xyuas pib yuav tsum ua raws li cov kev cai ntawm GB / t3956.

4. Lub zog zaus tuaj yeem ntsuas qhov ntsuas hluav taws xob: 3.5kv / 5min yam tsis muaj kev puas tsuaj.

Lub hom phiaj tseem ceeb:

Cov khoom no yog tsim rau kev xa hluav taws xob thiab kev xa tawm hauv kab nrog AC ntsuas hluav taws xob ntawm 0.6 / 1kv. Flame retardant fais fab cables yog tsim rau lub sijhawm uas xav tau cov nplaim hluav taws.

Cov kab hluav taws xob tiv thaiv hluav taws xob yog tsim rau cov tsev siab siab, cov khw loj loj thiab lwm qhov chaw muaj neeg coob.

Cov yam ntxwv ntawm nplaim retardant:

1. Cov nplaim hluav taws kub hnyiab tau tuaj yeem tiv taus GB / t18380 3. Specified bunched combustion test;

2. Cov pa luam yeeb concentration thaum combustion yuav tsum ua raws li GB / t17651 1;

3. HCl cov ntsiab lus hauv combustion precipitated gas yuav tsum tsawg dua los yog sib npaug li 100mg / g;

4. Hluav taws kub resistant cable tuaj yeem tiv taus GBA / t12666 6. Kev ntsuas hluav taws kub tshwj xeeb.
