Abstract

The invention discloses a novel busbar, and belongs to the technical field of wiring system. The novel busbar comprises a busbar main body; the surface of the busbar main body is successively providedwith an internal flame retardant layer, a heat absorbing layer, and an external flame retardant layer; the paint of the external flame retardant layer comprises, by weight, 65 to 80 parts of toluenediisocyanate, 45 to 55 parts of a polyether glycol, 10 to 12 parts of polydimethylsiloxane, 8 to 10 parts of epoxy resin, 2 to 4 parts of a metal oxide, 3 to 6 parts of graphene, 3 to 5 parts of ammonium polyphosphate, 1 to 2 parts of melamine, 4 to 6 parts of pentaerythritol, 2 to 3 parts of diethyl toluenediamine, 2 to 4 parts of trimethylol propane, and 3 to 4 parts of dibutyltin dilaurate. Thepaint flame resistance is improved obviously, generation of smoke is inhibited, and the mechanical properties are improved greatly.

Description

technical field [0001] The invention relates to the technical field of wiring systems, in particular to a novel busbar and a manufacturing process. Background technique [0002] In electrical insulation products, the heat-shrinkable sleeve for busbar insulation provides insulation protection for copper bars, preventing accidents caused by live bare wire bars, and preventing short circuits and leakage caused by small animals. Reduce the distance of copper bars and provide greater design freedom. In the limited space of switchgear, under the rated voltage of 35kv, it can effectively prevent dust, pollution, and condensation flashover. At present, the flame retardant and fireproof performance of the existing busbar still needs to be improved. If the flame retardant performance of the busbar is not up to the standard, it will bury hidden dangers for the safety of power equipment. Contents of the invention [0003] In order to solve the above technical problems, the present in...
