BBTRZ cable hu ua MI cable, siv los ntawm Switzerland, Tuam Tshoj yog los ntawm xyoo 1960s pib maj mam nkag mus rau hauv kev ua lag luam, vim tias cov khoom siv tsis zoo, yog li cov hluav taws kub ua tau zoo dua, cov cwj pwm hauv tsev hu ua magnesium oxide cable lossis refractory cable, tam sim no raws li cov yam ntxwv ntawm cov qauv yuav muab faib ua nruj thiab hloov tau ob yam.
Qhov sib txawv loj tshaj plaws nyob rau hauv cov qauv tsim ntawm cov nplaim hluav taws kub-retardant cables yog cov hlau hydrate inorganic xws li aluminium hydroxide, magnesium hydroxide es tsis txhob siv cov hlua polypropylene los yog iav fiber, hlau hydrate hloov mus rau hauv cov hlau oxide thiab dej hauv qab nplaim taws, uas tsis yog tsuas txo qhov kub ntawm cov kab hluav taws kub, tab sis kuj nws cov seem yog densely qhwv nyob rau hauv insulated hlau core. Yog li ntawd nws tsis tuaj yeem koom nrog cov tshuaj tiv thaiv cov pa kub, yog li txawm tias lub peev xwm ntawm cov cables hauv qhov tso tawm ntau tshaj 28L / m, nws yuav tua tus kheej tam sim ntawd (nws cov qauv carbonization raug txo los ntawm 2.5m mus rau tsawg dua 1. {6}}m).
