Gyffredinol

Mae bushing crebachu thermol fflam yn ymfalchïo mewn arafiad fflam da, inswleiddio, meddalwch, tymheredd isel a chrebachu cyflym. Fe'i defnyddir yn helaeth mewn cysylltiad gwifren, amddiffyn weldio, marcio gwifren, amddiffyn inswleiddio gwrthiant a chynhwysydd, amddiffyn cyrydiad bar metel neu diwbiau, a'r amddiffyniad antena.
Egwyddor crebachu thermol: O dan yr ymbelydredd ynni uchel, gall yr LI ger polymer ffurfio strwythur traws-gysylltiedig rhwydwaith. Mae cryfder mecanyddol, tymheredd, toddiant cemegol a gwrthiant heneiddio polymer traws-gysylltiedig yn cael eu gwella'n fawr, yn enwedig yr ymwrthedd asid ac alcali.
Lliw: du, coch, glas, gwyn, melyn, gwyrdd a thryloyw. A gellir addasu lliwiau eraill.
Cymhareb Crebachu: 2: 1. Foltedd Graddedig: 600V.
