HEATING CABLES K12C HEATING CABLES WITH CONSTANT ANTIFREEZE POWER FOR PIPES ■ Suitable for protection against freezing pipes for misting, irrigation and fire prevention systems ■ Constant power delivered ~10 W/m CODE Cable Minimum Maximum Maximum length length installation room room temperature of the heating circuit temperature powered from the supply point K12C25 25 m -20 °C 40 °C 160 m K12C50 50 m -20 °C 40 °C 160 m K12C75 75 m -20 °C 40 °C 160 m HOMOLOGATION AND STANDARDS OPERATION ■ The heating cables consist of a coil-wound resistance on two conductors. The resistance is in contact with the conductors through splicing points at constant intervals; the energy to heat the resistance is drawn at the splicing points; ■ The total power of the cable is determined by a combination of temperature, length of the heating circuit and supply voltage; ■ They require control thermostats to be used to function. 1 K12C - HEATING CABLES WITH CONSTANT ANTIFREEZE POWER FOR PIPES INSTALLATION ■ The cable can only be cut at the indicated splicing points; ■ Minimum bending radius 20 mm; ■ The length of the cable varies according to the diameter of the pipe; ■ The cable must be secured along the pipe with the relevant fixing tape code K50 for steel pipes or code K50AL for plastic pipes; ■ In the case of large pipes, the strips may need to be wound so as to ensure adequate heat; ■ The conductors have cold tails and can be connected directly to the thermostat or to the junction box; ■ At the end of the cable, the 2 conductors must be kept insulated and must not come into contact with each other; use the kit to seal the terminals for cables with constant power (for 1 cable) code KIT1A; ■ It is advisable to apply an insulating coating over the heating cable for a correct installation; ■ Refer to the table to check whether the cables must be wound in a spiral with an increase in the required length.
