Kev Tiv Thaiv Kev Rwb Thaiv: Haum rau ntawm qhov chaw sab nraud ntawm txheej rwb thaiv tsev, nws ua kom lub zog hluav taws xob sib xws thiab muab kev hloov pauv zoo rau txheej tiv thaiv hlau sab nraud.

Cov Khoom Siv: Ob qho tib si yog cov khoom siv semiconductive crosslinkable, nrog rau qhov ntim resistivity feem ntau tswj tau hauv qhov ntau ntawm 10² txog 10⁵ Ω·cm.

3. Txheej rwb thaiv tsev

Kev Ua Haujlwm: Muab kev rho tawm hluav taws xob, tiv taus qhov hluav taws xob ua haujlwm thiab overvoltages kom tiv thaiv kev tawg lossis xau.

Cov Khoom Siv: Cov khoom siv tseem ceeb yogPolyethylene sib txuas (XLPE)Cov roj hmab Ethylene Propylene (EPR) siv rau cov ntawv thov hluav taws xob nruab nrab thiab cov ntawv thov yooj ywm siab. Polyvinyl Chloride (PVC) feem ntau siv rau hauv cov tes hauj lwm faib hluav taws xob qis.

4. Txheej Hlau Tiv Thaiv

Kev Ua Haujlwm: Muab txoj hauv kev rau qhov txhaum tam sim no, kev tiv thaiv hluav taws xob, thiab kev tiv thaiv av.

Cov Ntawv:Daim kab xev tooj liabkev tiv thaiv, kev tiv thaiv hlau tooj liab, lossis cov ntaub thaiv hlau corrugated (uas kuj muab kev ua haujlwm thaiv dej radial).

5. Txheej Txheem Sau

Kev Ua Haujlwm: Sau cov qhov khoob hauv cov xov hlau ntau lub hauv paus kom tswj tau qhov ruaj khov ntawm cov qauv, thiab muab kev tiv thaiv thiab kev tiv thaiv dej noo.

Khoom siv: Cov ntaub ntawv tsis-hygroscopic xws li polypropylene (PP) ripcord lossis cov hlua thaiv dej.

6. Sab Hauv Sheath

Kev Ua Haujlwm: Tiv thaiv cov hlau tiv thaiv txheej los ntawm kev xeb thiab muab cov dej radial thiab cov dej noo ua ntej.

Cov Khoom Siv: Cov hnab yas Polyethylene (PE) lossis Polyvinyl Chloride (PVC). Rau cov ntawv thov uas xav tau kev thaiv dej zoo, cov hnab yas aluminium-polyethylene laminated feem ntau siv.

7. Txheej Txheem Cuab Yeej

Kev Ua Haujlwm: Muab kev tiv thaiv kho tshuab tiv thaiv kev tsoo thaum lub sijhawm faus ncaj qha, rub thaum lub sijhawm teeb tsa, thiab kev nruj thaum lub sijhawm tso dej hauv qab dej.

Hom: Cov hlau nplaum armor (feem ntau yog rau compressive tsis kam) lossis hlau hlau armor (rau tensile lub zog).

8. Sab Nraud Sheath

Kev Ua Haujlwm: Txheej sab nraud tshaj plaws ntawm kev tiv thaiv, tiv taus kev xeb ib puag ncig.

Khoom siv: PVC lossis PE sheath khoom, nrog rau qhov ua tau los tsim cov nplaim taws-retardant, halogen-free, thiab cov ntaub ntawv tshwj xeeb sheath qis-pa luam yeeb.

9. Cov Kev Tsim Kho Tshwj Xeeb

Cov Qauv Tiv Thaiv Dej: Cov hlau corrugated sheaths lossis hmoov / daim kab xev / gels thaiv dej.

11. Cov Lus Qhia Luv Luv

Ib txoj hlua fais fab yog ib yam khoom siv uas tau tsim tshwj xeeb heev. Kev xaiv cov ntaub ntawv thiab kev siv cov txheej txheem rau txhua txheej muaj feem cuam tshuam rau kev ua haujlwm ntawm txoj hlua, lub neej ua haujlwm, thiab qib kev nyab xeeb. Cov thev naus laus zis niaj hnub no tab tom txhim kho mus rau qib hluav taws xob siab dua, muaj peev xwm ntau dua, muaj kev ntseeg siab dua, muaj kev txawj ntse ntau dua, thiab txhim kho kev ruaj khov ntawm ib puag ncig.
