1.Introduction
1) Used in tensile property test for cables, overhead stranded conductor, composite stranded conductor.
2) To determine tensile force RTS, max. Allowable tensile force MAT, 20% RTS, 40% RTS, 60% RTS, 2%-100% RTS, tensile force and stress-strain property of optical fiber composite overhead ground wire (OPGW), creep property for 1000 hours.
3) Used for OPGW optical cables, OPPC cables, ADSS cables, OPLC cables, aluminum stranded conductor, aluminum alloy stranded conductor, Anticorrosive ACSR, high strength steel stranded wire, Al-clad steel stranded wire, Concentric layer stranded wire, etc.
