The shank of bolt of described two copper bus-bar lap-joints is with insulating sleeve, and the nut place of next-door neighbour's stud is provided with the bowl-type rubber pad circle, and each copper bus-bar bilateral symmetry between the bowl-type rubber pad circle is fixed with pressing plate, insulating joint dividing plate and copper bus-bar respectively successively.
The transversal face length of described copper bus-bar and wide ratio are 24: 1～32: 1, and under the situation that does not change copper bus-bar cross-sectional area and length, surface area increases.
Described insulated support is made up of a plurality of dielectric support block, back-up block body one side that is close to left and right side plate is provided with half groove that supports copper bus-bar, intermediate supports block body both sides respectively are provided with half groove that supports copper bus-bar, the back-up block middle and lower part is provided with through hole, concavo-convex adaptive between back-up block and the back-up block through hole, be connected in series fastening between back-up block and the back-up block with bolt.
Described insulated support adopts GM prime modulus compression molding material to make.
The beneficial effects of the utility model are: because copper bus-bar adopts under the situation that does not change its cross-sectional area and length, increase the structure of surface area, effectively improved the radiating efficiency when the copper bus-bar current-carrying is worked, thereby increased the ampacity of copper bus-bar; Dielectric support block has been compressed the safe distance of former copper bus-bar, makes the volume-diminished of isolated bus groove, is applicable to the installation of any place, has improved the efficient of installing engineering; When copper bus-bar is connected with copper bus-bar is vertical, adopt two copper bus-bars to overlap, and by bolted, this overlapping mode intuitively, firmly, not yielding, guaranteed that the conductive section when copper bus-bar vertically connects does not lose.
