무볼트 체결 케이블 트레이 접합부의 전기적 특성 평가

초록

This paper deals with characteristics of electrical properties of non-bolting jointed cable tray. Traditional cable tray is used for a bolt-nut coupling method requiring long working hours and high wages. Developed non-bolting type cable tray improves the efficiency of construction work. IEC 61537 offers technical standards of electrical continuity. So we measured the electrical continuity of connection section to ensure compliance with IEC 61537 technical standards.
