PURPOSE: A heterogeneous metal sleeve for preventing the illegal construction practice of a distribution line is provided to prevent the damage of the distribution line by displaying the compression order and the compression portion in a heterogeneous metal sleeve surface space. CONSTITUTION: A heterogeneous metal sleeve which is used when a wire and a machining gas opening/closing device lead wire are connected in a machining distributing passage is compressed. No. 1 is inscribed between the inner side line(210) of S-4, Y-35, and U316 and the inner side line(220) located on the left side of a copper line 125SQ. No. 2 is inscribed between the outer side line(110) of a copper line 125SQ and the inner side line(220). No. 3 is inscribed between the inner side line(210) of S-4, Y-35, and U316 and the inner side line(220) located on the right side of aluminum 160SQ. No. 4 is inscribed between the outer line(100) located on the left side of the aluminum 160SQ and the inner side line(200). The heterogeneous metal sleeve is compressed in the order of No. 1, No. 2, No. 3, and No. 4.
