Issiqlikka chidamli elektr simi SWG 20-32 Yumshoq tavlanadigan yorqin FeCrAl1Cr13Al4Fekral qarshilik isitish simi

Xususiyatlari:

- Fekral elektr qarshilik isitish qotishmalari yuqori elektr qarshiligi, qarshilikning harorat koeffitsienti kichik. – Yuqori haroratda yaxshi korroziyaga chidamliligi va ayniqsa oltingugurt va sulfidli gazda foydalanish uchun mos, past narx. - Elektr qarshilik isitish simi fekral qotishma oddiy materialning bir turidir.

Ilovalar:

- U sanoat pechlari, maishiy texnika, sanoat pechlari, metallurgiya, mashinasozlik, samolyotlar, avtomobilsozlikda keng qo'llaniladi.
isitish elementlari va qarshilik elementlarini ishlab chiqaruvchi harbiy va boshqa sanoat tarmoqlari.

Hajmi o'lchov diapazoni:

- Tel: 0,01-10 mm
- Lenta: 0,05 * 0,2-2,0 * 6,0 mm
- Ip: 0,05 * 5,0-5,0 * 250 mm
- Bar: 10-50 mm
