Abstract
The utility model relates to a fireproof cable branch box which comprises a copper box body (1) and is characterized in that the copper box body (1) is formed by buckling of two oppositely-arranged half box bodies; the inner wall of each half box body is provided with a first side surface ceramic inner container (4), a second side surface ceramic inner container (5) and a frame-shaped ceramic inner container (6). The fireproof cable branch box is used for fireproof cable branches and comprises two parts made of ceramic materials. The outer box is made of red copper material which is the same as the materials of the fireproof cable. For the fireproof cable branch box, the ceramic inner containers are used so as to be capable of increasing the strength, effectively insulating heat and playing a good insulation role. As the branch points and joints of the fireproof cables are the weakest insulating positions, the ceramic inner container can effectively prevent interphase short circuit and short circuit between space cable cores and the outer sheaths.
Description
Technical field
The utility model relates to cable connecting arrangement, especially a kind of fireproof cable feeder pillar.
Background technology
At present, cable branch is to tell less relatively cable and wire to each layer on main cable, and cable branch box is exactly to be used for doing the chest that cable branch connects.
Yet for fireproof cable, its feeder pillar has fire prevention, insulation property too, and common cable branch box is difficult to satisfy the requirement of fireproof cable.
Summary of the invention
The purpose of this utility model is to provide a kind of fireproof cable feeder pillar, and this fireproof cable feeder pillar has solved the technical problem of the fire prevention when connecting of fireproof cable branch, heat insulation, insulation.
The technical solution of the utility model is:
A kind of fireproof cable feeder pillar comprises copper casing, and described copper casing is fastened by two half chests bodies that are oppositely arranged and forms, and is provided with the first side ceramic liner, the second side ceramic liner and shaped as frame ceramic liner respectively on each described half chests body inwall.Described copper casing is provided with location hole.Described copper casing one side is provided with a branched hole.
Described copper casing one side is provided with two branched holes.
The described first side ceramic liner is provided with a semi-circular hole corresponding with branched hole.
The described second side ceramic liner is provided with two semi-circular hole corresponding with branched hole.
The beneficial effects of the utility model are:
Fireproof cable feeder pillar of the present utility model is used for fireproof cable branch, and this fireproof cable branch casing is by two parts inner bag ceramic material.Outer container is that the red copper material is identical with the fireproof cable material.
The fireproof cable feeder pillar uses the ceramic liner advantage:
1. can increase feeder pillar intensity.
2. can be effectively heat insulation.
3. can play good insulating effect, fireproof cable breakout and joint are the weakest parts of fireproof cable insulation, so the use ceramic liner can effectively prevent short circuit between the core and oversheath between phase fault, line.
