The invention discloses a corrosion prevention, high temperature resistance, steel wire armored and tearing resistance flat cable. A protective layer is arranged outside a protective sleeve and can prevent a conductor and a rubber protective sleeve from being damaged by higher tearing force during the reciprocating dragging of the flat cable, wherein the protective layer comprises steel wire woven armor formed by weaving multiple strands of galvanized steel wires and an external fiber coating layer arranged outside the steel wire woven armor, and spaces among the protective sleeve, the steel wire woven armor and the external fiber coating layer are filled with binders. The steel wire woven armor is made of galvanized steel wire, and has favorable mechanical property, namely favorable tensile strength and tearing resisting strength; the external fiber coating layer is made of fibre glass, and can provide favorable properties of high temperature resistance and corrosion prevention; and the binders prepared from epoxide resin can prevent the mutual friction of the protective sleeve, the steel wire woven armor and the external fiber coating layer, enhance the integral strength of the protective sleeve and prevent outside corrosive liquid from corroding the protective sleeve.
