EXPLOSION-PROOF CASING

摘要

The invention relates to an explosion-proof casing which is designed for the encapsulation of an electrical equipement in potentially explosive environment According to the invention, the casing comprises one or more connected compartments, covered by lids which are seldom detached and a principal compartment (A) on which a joining piece (4) having a lid (5) with current opening, mounted on it, in this case the joining surface being built like a frame or a circular crown or a truncated cone The present invention has the advantage of making the second or multiple reuse in case of antideflagrating surfaces damage because the frame of connected compartments has such size that makes possible two or more rectifications
