Elektrikli bile\u015fenlerin yak\u0131n\u0131nda, dielektrik de\u011ferlerini bilmeden silikon levhalar kullan\u0131yorsan\u0131z ciddi bir risk al\u0131yorsunuz demektir.<\/p>\n\n\n\n

Silikon levhalar, genellikle 20 ila 30 kV\/mm aras\u0131nda de\u011fi\u015fen y\u00fcksek dielektrik dayan\u0131ma sahiptir ve bu da onlar\u0131 elektrik ve elektronik uygulamalar\u0131nda ideal yal\u0131tkanlar haline getirir.<\/strong><\/p>\n\n\n\n

Dielektrik dayan\u0131m sadece bir say\u0131 de\u011fil, bir g\u00fcvenlik garantisidir.<\/p>\n\n\n\n

Dielektrik dayan\u0131m, bir malzemenin elektriksel olarak bozulmadan dayanabilece\u011fi maksimum voltajd\u0131r; silikon levhalar i\u00e7in bu de\u011fer genellikle 20-30 kV\/mm aras\u0131ndad\u0131r.<\/strong><\/p>\n\n\n\n

Malzemenin elektri\u011fi iletmeden \u00f6nce ne kadar gerilime dayanabilece\u011fini g\u00f6sterir.
