Abstract
The invention relates to a penetration isolation seal assembly of an electric cable, which is applied to occasions of shipping, electric power, petroleum chemicals, aerospace, mechanical equipment, buildings, communication, transportation and the like, requiring the penetration isolation seal of electric cables, optical cables and copper bar buses. The penetration isolation seal has the general requirements of water proofing, fire proofing, earthquake resistance and vibration resistance, explosion resistance or explosion proofing, corrosion resistance, rat prevention, weather resistance, no halogen or ROHS, small mounting occupation area and convenient line change or electric cable number increase and decrease. The penetration isolation seal assembly realizes the water proofing function by utilizing the elastic compression of an elastic material and meets the fire proofing requirement of a fire proofing expanding material. The invention solves the technical problems that the seal assembly of the prior art is easy to loosen and has inconvenient maintenance and installation and high cost. The scheme combines the respective performances of the elastic material, the fire proofing expanding material and a shielding material to form an annular cylinder; the inner diameter of the annular cylinder is matched with the wire diameter of the electric cable, which permits the electric cable to pass through the cylinder, and the seal is realized when the electric cable passes through a deck, a wall and the shell of a case under the action of a pressure device. The invention provides a solution with convenient maintenance and installation and low cost.
