Ib shielded tswj cable feem ntau yog siv los ua cov kab txuas ntawm cov cuab yeej hluav taws xob.
Nws yog qhov tsim nyog rau kev sib txuas ntawm cov cuab yeej hluav taws xob nrog AC-rated voltage ntawm 450/750V thiab hauv qab no thiab cov kab sib txuas ntawm kev tswj tsis siv neeg.
Nws muaj cov khoom zoo xws li roj tsis kam, dej tsis kam, hnav tsis kam, acid thiab alkali tsis kam, tsis kam mus rau ntau yam corrosive gases, kev laus tsis kam, thiab tsis-combustibility.
Ib shielded tswj cable yog ib lub cable nrog ib txheej ntawm mesh tooj liab los yog hlau hlau woven nyob ib ncig ntawm ib los yog ntau tshaj nyob ntawm tej. Cov txheej ntawm cov hlau mesh no tuaj yeem tiv thaiv kev sib tsoo thiab cov teeb liab sab nraud tsis tuaj yeem cuam tshuam nrog nws.
Cov ntaub thaiv npog kuj muab qee qhov kev tiv thaiv tawm. Yog tias lub cable puas thaum siv thiab xau, cov ntaub thaiv npog tuaj yeem coj cov xau tam sim no mus rau hauv av xaim, muab qee qhov kev tiv thaiv kev nyab xeeb.
Lub luag hauj lwm ntawm shielding thiab grounding hlau ntawm shielded tswj cable yog hais tias lub shielding txheej yog muab faib ua internal shielding thiab lwm shielding..
Lawv yog ob qho tib si ua kom muaj kev sib cuag zoo ntawm tus neeg xyuas pib cable thiab txheej rwb thaiv tsev, thiab nruab nrab ntawm txheej rwb thaiv tsev cable thiab txheej tiv thaiv sab hauv, txhawm rau tshem tawm qhov nce ntawm qhov hluav taws xob sab hauv lub zog uas tshwm sim los ntawm qhov tsis zoo ntawm tus neeg xyuas pib thiab cov txheej txheem tiv thaiv sab hauv.
Cov yam ntxwv ntawm cov khoom siv shielded tswj cables.
(1) Tso cai khoov vojvoog ntawm lub cable: qhov tsawg kawg nkaus dabtsi yog khoov vojvoog ntawm ib tug uas tsis yog armored cable yog 6 lub sij hawm sab nrauv txoj kab uas hla ntawm kab. Fluoroplastic insulated thiab sheathed cables yuav tsum yog tsawg kawg 8 lub sij hawm ntawm sab nraud txoj kab uas hla. Copper daim kab xev shielded los yog steel daim kab xev armored cable yuav tsum yog yam tsawg kawg nkaus 12 lub sij hawm ntawm sab nraud txoj kab uas hla.
(2) Ua haujlwm kub siab tshaj plaws: polytetrafluoroethylene propylene (F46) rwb thaiv tsev yuav tsum tsis txhob tshaj 200 ℃. Soluble polytetrafluoroethylene (PFA) rwb thaiv tsev yuav tsum tsis txhob tshaj 260 ℃.
(3) Yam tsawg kawg ambient kub. PVC hnab: tsau tso -40 ℃, Tsis-taw tso -15 ℃. fluorine yas thiab silicone roj hmab sheath: tsau tso -60 ℃, Tsis-taw tso -20 ℃. Cable installation thiab tso qhov kub thiab txias yuav tsum tsis txhob qis dua 0 ℃ (fluoroplastic, silicone roj hmab thiab nitrile sheathed cable yuav tsum tsis txhob qis dua -25 ℃).
