• Items tubular flat with cover in stainless steel AISI 321, resistive wire Alloy Nickel-Chrome Quality 80-20 Isolated case with highly compacted magnesium oxide with very good Thermal Conductivity • Ohmic Values:
– Minimum: 8 W por metro
– Maximum: 1500 W per meter for resistance 2 drivers
• Longitude Máxima:
– RKF 13 ® 7000 mm for all lengths
– RKF 17 ® 5000 mm for all lengths
– RKF 22 ® 5000 mm for all lengths
• Length tolerance: ± 1% with a minimum of ± 5 mm
• Zone inactive: Due to Process productive, all RKF flat tubular elements having inactive area on the side of the minimum connections 45 mm and the minimum tube end 25 mm for all lengths.
• Connects: Add to Salida O1, 8 x 30 mm for all lengths. Other connection options on request.
• Custom-made: RKF flat tubular elements can be supplied with longer inactive areas. Also, can also be manufactured with different power distributions over the length.
Sections
• RKF 13. Section 13 x 5,5 mm for all lengths
For this section, resistance is approx. a surface of 3,3 cm ² per cm of length. The maximum length of 7000 mm for all lengths. For heating applications of railways can provide it standard models with different power densities and watertight connection.
• RKF 17. Section 17 x 6 mm for all lengths
For this section, resistance is approx. a surface of 4,1 cm ² per cm of length. The maximum length of 5000 mm for all lengths. It is the most widely used industrial applications. With its longer length allows for a variety of forms, while various provisions of the internal resistance and power distributions.
• RKF 22. Section 22 x 6 mm for all lengths
For this section, resistance reaches a surface approx. de 5,1 cm ² per cm of length. The maximum length of 5000 mm for all lengths. As the type RKF 17, is possible to perform a variety of provisions of the internal resistance.
