Isihlukanisi sebhethri ye-Fiberglass ukuhlukaniswa phakathi komzimba webhethri ne-electrolyte, edlala indima enkulu yokuhlukaniswa, ukuqhutshwa kwe-conductivity kanye nokwandisa amandla ebhethri. Isihlukanisi sebhethri asikwazi nje ukuthuthukisa ukusebenza kwebhethri, kodwa futhi sithuthukise ukusebenza kokuphepha kwebhethri, ukuqinisekisa ukusebenza okuzinzile kwebhethri. Isihlukanisi impahla ngokuyinhloko fiberglass, ukujiya yayo ngokuvamile 0.18mm ukuze 0.25mm. Isihlukanisi sebhethri ye-Fiberglass njengengxenye ebalulekile yebhethri, idlala indima ebalulekile ebhethri. Izinhlobo ezahlukene zezihlukanisi zamabhethri zinezinzuzo zazo kanye nokubi futhi zifanele izimo ezihlukene zohlelo lokusebenza. Ukukhetha okubalulekile kwesihlukanisi sebhethri se-fiberglass akugcini nje ngokuthuthukisa ukusebenza kwebhethri, kodwa futhi kunciphisa amathuba okonakala kwebhethri, ngaleyo ndlela kukhulisa impilo yesevisi nokuphepha kwebhethri.
