Construction of the insulation in joints for high tension electric cables

Claim 1

THE IMPROVEMENT IN THE METHOD OF CONSTRUCTION OF THE INSULATION OF NORMAL JOINTS FOR HIGH TENSION ELECTRIC CABLES INSULATED WITH IMPREGNATED PAPER, CHARACTERIZED BY COMPRISING THE FOLLOWING OPERATIONS: MAKING A CONDUCTIVE CONNECTION BETWEEN THE CONDUCTORS OF THE CABLE CORES THAT ARE BEING JOINED AND FORMING WINDINGS OF AUXILIARY SPACED APART PAPER TUBES HAVING SMALL THICKNESS SURROUNDING THE INSULATION ON THE ADJACENT CYLINDRICAL ENDS OF THE RESPECTIVE CABLE CORES THAT ARE BEING JOINED, THE TWO AUXILIARY TUBES BEING WOUND IN OPPOSITE DIRECTIONS ON THE CORE ENDS SO THAT EACH OF THEM AIDS IN THE TENSION OF THE UNDERLYING EXTERNAL TAPE OF ITS CORE, THEN FILLING OF THE SPACE INCLUDED BETWEEN THE OPPOSITE ENDS OF THE PAPER TUBES BY WINDING ON THE CONDUCTIVE CONNECTION BETWEEN THE JOINED CONDUCTORS SOLID INSULATION IN AN AMOUNT TO OBTAIN A UNIFORM CYLINDRICAL SURFACE HAVING A DIAMETER EQUAL TO THE OUTSIDE DIAMETER OF THE AUXILIARY PAPER TUBES, AND THEN WINDING A SINGLE OUTER PAPER TUBE ON THE WHOLE OF SAID CYLINDRICAL SURFACE.
