Meter thawv yog cov cuab yeej siv los khaws cov ntsuas hluav taws xob. Cov khoom siv los tsim cov casing ntawm tsawg-voltage cable ceg thawv yog cov khoom siv cob-raws li cov khoom sib xyaw. Cov khoom tseem ceeb ntawm lub casing yog txhaj molded thiab nias los ntawm plaub cov ntaub ntawv: ABS engineering yas, pob tshab polycarbonate (PC), DMC, thiab SMC.
Cov khoom sib xyaw no muaj ob ntu: matrix-polyester resin; thiab cov ntaub ntawv txhawb zog (PC thiab SMC), yog li nws tseem hu ua pob tshab PC khoom lossis fiber ntau -cov khoom siv polyester. Cov ntaub ntawv PC pob tshab thiab fiber ntau-cov khoom siv tsis muaj zog polyester yog cov khoom sib xyaw nrog cov khoom siv tsis zoo polyester li matrix. Ob leeg ntawm cov ntaub ntawv no yog insoluble, nplaim taws-retardant, thiab recyclable. Cov khoom siv tom kawg, txawm li cas los xij, tsis yog -kua thiab tsis yog - rov ua dua. Nws lub cev qauv yog peb- qauv kev sib txuas. Cov ntaub ntawv plaub no, dhau los ntawm kev hloov pauv hloov pauv thiab kev txhawb nqa nrog cov fibers tshwj xeeb, tau dhau los ua cov khoom siv ua haujlwm siab -.
