5.3 설치 참고 사항
- 케이블 전처리
Clean cable surface thoroughly with 3M CC-2 cleaning kit.
Smooth transition at shield cutting position to avoid corona discharge.
- 설치 단계
QTII series: Install branch sealing & stress mastic first, then termination body.
QTIII series: 통합 디자인, no extra stress mastic needed, simpler installation.
- 안전 규정
설치자는 유효한 고압 케이블 건설 자격을 보유해야 합니다..
Ensure cable de-energized and grounded before work.
- 품질 관리
Conduct insulation resistance test and partial discharge test after installation.
Record installation date and test data for later maintenance.
- Difference between QTII and QTIII Series
QTIII is 3rd generation technology, grease-free, 낮은 부분방전 (≤5pC), easier installation; price about 20% higher than QTII.
- How to select correct insulation outer diameter range
Measure actual cable main insulation outer diameter, select the smallest model covering the measured size to ensure sufficient radial compression.
- Interchangeability of indoor and outdoor types
Outdoor type can be used indoors; indoor type cannot be used outdoors (no rain shed, insufficient protection).
- Difference for copper core vs aluminum core cable
3M medium voltage cold shrink terminations fit both copper and aluminum conductors without special model selection.
