According to GOST 994−74 10, Nichrome in isolation is used electrical heating devices of high reliability. The insulation material is ordinary STEKLONIT, polyvinylchloride or enamel (enamel wire) for the Nichrome wire Cr20Ni80. The base of the heating element — wire Cr20Ni80 has a high electrical resistance of 1.12 ohm mm 2 / m. The minimum coefficient of thermal expansion allows a wire sag is not at significant temperatures. Surface oxides of chromium and nickel gives it excellent corrosion resistance, heat resistance Sufficient allows to use it in a wide temperature range. It can withstand a large number of off-switching cycles without breaking.
For the central current-carrying conductors using Nichrome thread brand Cr20Ni80 Ø 0.2−2 mm. The material for insulation — STEKLONIT thickness 2 ± 0,2 mm is wound on a wire turn to turn. Breakdown voltage insulation should be greater than 1250 volts. Winding should be carried out in a single layer, as otherwise there is substantial overheating. The smallest diameter of the bending GIN must be at least five times the cross section of the current-carrying conductors. All regulated requirements of the technical specifications on the GIN.
Nichrome in isolation is relevant in the heat of action devices: industrial furnaces, drying and firing. It is used to heat the building structures, heating car seats, production of muffle furnaces, water heaters. Nichrome is a special value in the aggressive environment of industrial condensates.
