Rezistans Telleri
Rezistans telleri bütün rezistansların imalatında kullanılan elektrik enerjisini ısı enerjisine dönüştürmeye yarayan, yüksek dirençli ve yüksek sıcaklık dayanımı olan tellerdir.
Stoklarımızda 0,10 mm den 7 mm e kadar, CrAl serisi ve CrNi serisi bulunmaktadır.
Firmamız rezistans tellerinde kendi markası olan THELECTRAL rezistans tellerinin ithalat ve ihracatını yapmaktadır.
0,10 mm den 1,30 mm e kadar plastik bobinlerde, 1,30 mm üzerindeki çapları kangal olarak satışa sunmaktayız.
