Zusammenfassung:The invention relates to a pressure balance guider and a method for lowering a heating steel cable by using the pressure balance guider. The pressure balance guider comprises a pressure balance cylinder and a guide head fixed at the bottom of the pressure balance cylinder, the top of the pressure balance cylinder is provided with an upper connector connected with the heating steel cable, a plurality of upper diversion holes penetrate through the upper end of the outer wall of the pressure balance cylinder, and a plurality of lower diversion holes penetrate through the lower end of the outer wall. The method for lowering the heating steel cable comprises the steps that a hanger shell and the pressure balance guider are assembled, an assembly is connected with a Christmas tree and a blowoutpreventer, and the heating steel cable is lowered. The hanger is simple in structure and easy to machine, plays a great role in the construction process, solves the phenomenon that the heating steel cable is blocked in the pr
