Dab tsi yog qhov zoo ntawm cov insulators sib xyaw?

Composite insulators muaj ib lub iav fiber ntau epoxy resin core pas nrig, silicone roj hmab sheds, thiab fittings. Lawv muaj cov khoom siv hluav taws xob zoo (tiv taus voltage Ntau dua lossis sib npaug rau 110kV) thiab cov khoom siv kho tshuab (lub zog tensile Ntau dua lossis sib npaug rau 120kN), thiab tau siv dav hauv cov kab sib kis.

Lawv cov txiaj ntsig tseem ceeb suav nrog:
1. Kev ua qias tuaj (hydrophobic silicone roj hmab nto, flashover voltage 30% -50% siab dua cov plooj (porcelain insulators), haum rau qhov chaw hnyav xws li cov ntug dej hiav txwv thiab thaj chaw muaj kuab paug;
2. Lub zog ua haujlwm siab (lub zog flexural Ntau dua lossis sib npaug ntawm 8kN·m), muaj peev xwm tiv taus cua txias (cua siab tshaj lossis sib npaug ntawm 3kPa) thiab icing loads (ice thickness ntau dua lossis sib npaug li 20mm);
3. Kev tsim qauv hnyav (qhov hnyav tsuas yog 1/5-1/10 ntawm cov plooj (porcelain insulators), txo cov nqi ntauwd thiab kev teeb tsa;
4. Anti-kev laus zog (UV tiv taus ntau dua lossis sib npaug li 5000 teev), nrog rau kev ua neej ntev tshaj 30 xyoo. Organic composite insulators ntxiv muaj cov yam ntxwv tiv thaiv ib puag ncig (tsis muaj nag lossis daus hnyav) thiab kev ua tau zoo ntawm dielectric (dielectric poob lub kaum sab xis tsawg dua lossis sib npaug li 0.2%), ua rau lawv tsim nyog rau cov xwm txheej xws li lub zog hluav taws xob tshiab.
