Electrically insulated resistors represent high-quality engineering where top-notch materials are employed. These resistors are composed of a nickel-chromium spiral and electrofused magnesium oxide, ensuring exceptional performance.

The external shielding of these resistors can be made from various materials, such as stainless steel, copper, titanium, incoloy 800, or Teflon (PTFE), depending on the specific applications they are used for. Moreover, they are highly versatile, as they can be manufactured in virtually any length, shape, or diameter, adapting to individual customer needs. These resistors are ideal for a wide range of applications, from heating liquids, solids, and gases to their use in water heaters, oils, chemical solutions, infrared elements, air conditioning batteries for heating, drying ovens, thermal treatments, and more.

What makes these resistors even more remarkable is their ability to withstand adverse conditions, including corrosion, vibration, impact, and high temperatures of up to 700°C. The choice of the appropriate shielding material depends on factors such as the required power, maximum permissible specific load in W/cm2, available dimensions, tube diameter and length, the medium to be heated, and operating temperature.

To ensure optimal performance, these resistors use electrofused magnesium oxide (MgO) as an insulator, providing efficient thermal conduction, electrical rigidity, and adequate insulation. The resistive element in the form of a spiral is composed of nickel-chromium, ensuring excellent energy efficiency.

Hermatic sealing against environmental moisture is achieved through the use of high-quality resins and silicones. Furthermore, a ceramic insulator is incorporated to guarantee dielectric insulation between the connection and the shielding, confirming the reliability and safety of these electrically insulated resistors in a wide range of applications.
