6kV Composite Surge Arrester

Zinc oxide surge arrester yog tus tshaj tshaj-voltage tiv thaiv nyob rau hauv lub ntiaj teb no. Vim ua rau cov resistor disc ntawm cov tub ntxhais tivthaiv feem ntau yog siv zinc oxide ntes. Piv nrog rau cov pa siliconcarbide tus neeg ntes, qhov tshuaj ntawm cov khoom no txhim kho cov yam ntxwv ntawm volt-ampere ntawm cov resistor disc thiab nce los ntawm-tam sim no muaj peev xwm ntawm over-voltage thiaj li coj lub rad zos-hloov rau cov yam ntxwv ntawm cov neeg ntes.Surge Tus ntes yog tsuas yog siv los tiv thaiv kev xa tawm transformer, cable connector thiab cov khoom siv hluav taws xob los ntawm kev puas tsuaj los ntawm lub teeb pom kev zoo thiab ua haujlwm dhau-voltage.
