Core Material Xaiv rau Insulated Ncej Connectors
Insulated ncej connectors yuav tsum ib txhij ua tau raws li txhua yam muaj zog thiab rwb thaiv tsev kev ua tau zoo. Cov ntaub ntawv tseem ceeb tam sim no muaj xws li:
Epoxy Resin: Flexural zog Ntau dua los yog sib npaug rau 120MPa (ib GB / T 1043-2008), qhov hluav taws xob tsis kam mus txog 30kV / mm, feem ntau siv nyob rau hauv high-voltage lag luam scenarios;
iav- fiber ntau reinforced yas: Tsawg ntom (1.8–2.1 g / cm³), tensile lub zog Ntau dua los yog sib npaug rau 300 MPa, haum rau portable insulated ncej;
Silicone roj hmab: Zoo elasticity thiab huab cua tsis kam, tab sis qis dua txhua yam, feem ntau yog siv rau kev sib khi txheej txheej.
Kev sib koom ua ke thiab daim ntawv thov scenarios
Muab faib los ntawm txoj kev sib txuas ua peb pawg:
Threaded Joints: Utilize precision thread engagement with pull-out resistance >5kN (IEC 60855 tus qauv), tsim nyog rau lub sijhawm ntev - cov khoom siv ua haujlwm ruaj khov;
Snap-Fit Joints: Feature ceev-tso tawm tsim nrog lub sijhawm sib dhos<10 seconds, but offer limited load capacity (<2kN), ideal for emergency repairs;
Ceev- txuas / txiav cov pob qij txha: Feature rau tus kheej- xauv cov txheej txheem nrog IP67 ntsuas dej tsis zoo (GB/T 4208-2017), feem ntau yog siv rau hauv qhov chaw ntub dej.
Qhov tseem ceeb Performance Parameters thiab Standards
Kev ua haujlwm hluav taws xob: Cov dej ntws tawm yuav tsum yog<1mA at 10kV voltage (DL/T 878-2021);
Mechanical Life: Threaded connectors yuav tsum tiv taus ntau dua los yog sib npaug rau 5000 qhov ntxig / rho tawm mus yam tsis muaj deformation;
Environmental Adaptability: Insulation resistance >1000MΩ nyob rau hauv -40℃rau +70℃ntau yam (IEC 61109).
Kev xaiv cov lus pom zoo thiab ceev faj
Ua ntej epoxy resin + threaded ua ke rau siab -voltage ib puag ncig;
Rau cov xwm txheej tsis sib xws, pom zoo kom snap- haum lossis ntsaws- nyob rau hauv hom nrog kev tshuaj xyuas tsis tu ncua;
Tsis txhob sib xyaw cov khoom sib txawv ntawm cov khoom sib txawv los tiv thaiv electrochemical corrosion.
