1.DeCoding Xhhw: rhuav tshem cov niam ntawv cov niam ntawv
Xhhw sawv rau dab tsi?
Tus XHHW cov ntawv sau nyiaj tawg rau hauv plaub qhov tseem ceeb:
X: Hla nrog Polyethylene rwb thaiv tsev
H: Tshav kub-resistant (75 degree ntub / 90 degree qhuav ntsuas)
H: Cov Hluav Taws Xob Ntau Tshaj Ntau Dua Li Cov Qauv Thermoplastics
W: Dej-resistant(Qhov tseem ceeb ntawm cov ntawv no)
Tus "W" tshwj xeeb qhia tau tias lub peev xwm ntawm lub peev xwm los ua haujlwm nyab xeeb hauvCov chaw ntub dejThaum siv nyob rau hauv nws cov kev ntsuas kub. Qhov no sib txawv XHHHW los ntawm cov ntoo sib thooj zoo li XHH (tsis muaj dej tsis kam) thiab XHWN (dej-tiv taus nylon tsho).
2.Qhov kev tshawb fawb tom qab XHHW hlau dej tsis kam
Yuav ua li cas XHHW ua tiav kev tiv thaiv noo noo
Rwb thaiv tsev ntaub: Hla-txuas Polyethylene (XLPE) ua cov nyom molecular tiv thaiv kev nkag mus

3.XHHW TAIS CABLE: Kev Siv Khoom Siv Industrial
Vim li cas XHHW Dominates Cable Tais Tshuab
Yam ruaj khov: Withstands kev ntxhov siab hauv cov tais nruab
UV Kuj: Haum rau sab nraum zoov cable
Tshuaj Kuj: Qhov zoo tagnrho rau cov chaw muaj kev lag luam
Qho kub tau yooj: Ua tau nyob rau hauv -40 degree rau 90 degree ranges
Kev sib piv: XHhW vs. Xhwn hauv tais Cable
