Load Resistor - 1.5MW - 3x690V

Mobile load resistor for test of wind turbines

Load resistor


SAN load resistor, load resistor 1.5MW - 3x690V, divided into 24 groups (group 1-2 690V / group 3-24 3x690V. Consisting of stainless steel frame covered by 2mm stainless steel plate, mounted with 252 off heating elements Ø10,2mm, equipped with terminal box with built-in temperature limiters type EGO, motor protection and ventilator.

Load resistor mounted with lifting brackets for transport and U-rails in the bottom in case of truck lifting together with grating at the outlet end. Terminal boxes are situated at the top of the load resistor, and raised 195mm due to heat transmission.
