PROBLEM TO BE SOLVED: To provide an insulation structure for the inside of a metal sheath and a metal sleeve which derives a high insulation performance of boron nitride at a realistic cost and also improves workability while maintaining an insulation property superior to a conventional insulation structure for the inside of a metal sheath or a metal sleeve filled with alumina or magnesium oxide, by using boron nitride.SOLUTION: The insulation structure is formed by filling a gap between a metal wire and a metal sheath or a metal sleeve with an insulation material inside of a metal sheath cable or inside of a metal sleeve of a connection which connects metal sheath cables or the metal sheath cable and another cable. The insulation structure is characterized in filling the gap with an insulative metal oxide and boron nitride as the insulation material. |
