● BCI series Variable Rheostat imavulazidwa ndi waya wamkuwa kapena chromium-alloy ngati chinthu chotsutsa. Kupatula pa malo okhudzana ndi slide, chigawo chonsecho chimakutidwa ndi utomoni wotentha kwambiri, wosayaka. Pambuyo pozizira ndi kuyanika, insulation imayikidwa kudzera ndondomeko yotentha kwambiri.Kenako, chigawo chowongolera chozungulira chimayikidwa, chomwe chimasuntha pamodzi ndi chinthu chotsutsa ndipo chimasinthasintha kukana kwa mtengo womwe ukufunidwa.
● BCI mndandanda wa ma rheostats adapangidwa ndikupangidwa kuti asunge kudalirika kwakukulu komanso kugwira ntchito bwino kwa nthawi yayitali. Ma rheostats awa amapangidwa kuchokera ku thupi la ceramic lomwe limakhala ndi zopinga za alloy ndi zokutira za vitreous enamel (kapena zokutira za silicone ceramic kutengera mtundu). Ma BCI rheostats ali ndi mkono wachitsulo wolumikizana ndi masika, mawonekedwe achitsulo a graphite ndi ma terminals okutidwa ndi solder.
● Chigawo chimodzi chokhala ndi mphamvu zambiri zokhotakhota chilipo.
● Zopangira zadothi zosiyanasiyana ndi makono, opangidwa kuti ayitanitsa ma rheostats omwe alipo.
