<p>An intensively insulated busway, comprising a busbar protective housing (10) and a busbar unit disposed inside the busbar protective housing; the busbar unit comprises a plurality of busbars (20), and the busbars comprise a conductor (21) and an insulating layer (22) covering the busbars; the plurality of busbars are arranged side-by-side and parallel to one another; the space between the busbar protective housing and the busbar unit is filled with fire-resistant material; an inorganic endothermic material (30) is provided inside the intensively insulated busway; the inorganic endothermic material is an inorganic material that absorbs heat when heated and also releases steam. By means of the inorganic endothermic material disposed within the intensively insulated busway, the fire-resistance properties of the busway are improved, the intensively insulated busway is better able to continue to supply power during a fire, and the duration for which the intensively insulated busway is able to supply power during a fire is prolonged.</p> |
