¡¡¡¡With the development of the power system and the improvement of power quality, corresponding power electronic technology is making great progress as well .In order to resolve the thermal emanation problem of the thyristor valve and the resistance in HVDV, FACTS etc., GWT has successfully developed the new-style accessories: the water cooling radiator and the water cooling resistance.

Characteristic
Water cooling radiator:
¡´ high thermal efficiency, low thermal resistance;
¡´ water circulating channels based on hydraulics model;
¡´low pressure loss;
¡´special material with high mechanical intensity and anti-erodible;
¡´ advanced manufacture technics.
Water cooling resistance:
¡´the all-around cooling mode;
¡´ water circulating channels based on hydraulics model;
¡´low pressure loss;
¡´built-in noninductive resistance with low tolerance, large overload capacity, hi-voltage-pulse-resistance and standard-lightning-surge-resistance,;
¡´ excellent shell material with steady performance of mechanism,chemistry and electric;
¡´ credible waterproof technology
