The invention discloses a double-layer self-balancing pulling cable thermostatic curtain wall system. According to the technical scheme, the double-layer self-balancing pulling cable thermostatic curtain wall system is characterized in that the system comprises an inner side curtain wall and an outer side curtain wall, a vertical bearing rod, horizontal support rods and stable steel cables are arranged between the inner side curtain wall and the outer side curtain wall, and the stable steel cables are fixedly connected with the inner side curtain wall and the outer side curtain wall in a spaced mode from top to bottom to form a rhomboid structure. By means of the double-layer self-balancing pulling cable thermostatic curtain wall system, the problems that an existing double-layer curtain wall is low in structural stability is solved; in addition, a temperature regulation device is arranged between the inner side curtain wall and the outer side curtain wall to cool or heat air in a curtain wall intermediate layer, therefore, a thermal insulation layer is formed, the temperature of a building on the inner side of the curtain wall is relatively stable and is not affected by the external temperature, the thermostatic effect is achieved, and therefore the energy-saving effect reaches 80%.
