The invention discloses an intrinsic safety type silicon rubber insulated cable with a Y-shaped nylon framework. A cable core comprises the Y-shaped nylon framework with a hollow structure, a plurality of small holes are evenly formed in the Y-shaped nylon framework, a drainage wire is arranged at the center of the Y-shaped nylon framework, a control wire core is respectively arranged two gaps of the Y-shaped nylon framework, a ground wire core is arranged in the other gap of the Y-shaped nylon framework and comprises a fan-shaped conductor, and the control wire core comprises two round conductors. The cable core is sequentially wrapped by a wrapping layer, a copper tape braided shielding layer and an outer sheath. The intrinsic safety type silicon rubber insulated cable adopts the Y-shaped nylon framework with the hollow structure, and the Y-shaped nylon framework is evenly provided with a plurality of small holes, so that the drainage wire can lead out current of any one leaked wire core, the using safety o
