150KN Multi-Segment Conductor Come Along Clamp for Heavy Duty ACSR Stringing

The SK50DP series Multi-Segment Type Conductor Wire Grip is a specialized, ultra-high-capacity mechanical matrix-clamping block engineered for ultra-high voltage (UHV/EHV) overhead power grid construction. Specifically designed to manage large cross-section conductors (Φ25mm to Φ50mm) such as heavy-duty ACSR, this tool utilizes an innovative independent segmented slice mechanism. Driven by a high-torque, multi-bolt matrix (up to 150N.m per bolt), it delivers an immovable, uniform mechanical hold up to 150KN without causing "bird-caging" (outer strand deformation) or slipping under extreme, long-span pulling tension.

Precision calibrated to guarantee absolute structural integrity for large-diameter bundled conductor stringing:

• Independent Segmented Slices (Self-Adaptive Fit): Traditional one-piece rigid jaws fail to align fully with naturally curved or undulating heavy conductors, concentrating stress on tiny spots. Our independent matrix segments mold seamlessly to the wire's contour, ensuring a perfect 360° concentric squeeze.
• Anti-Bird-Caging & Strand Protection: When pulling large ACSR under extreme tension, standard grips tend to strip or bunch up the outer aluminum layers. The multi-segment layout distributes the radial load evenly across a long horizontal plane, keeping the outer aluminum strands tightly bound to the inner steel core.
• Unmatched 150KN Load Security: Built from heavily heat-treated structural alloy steel, this 26kg industrial masterpiece stands up to a devastating 15-ton (150KN) peak tension load without threading failures, thread stripping, or body bending.
• High-Torque Matrix Stability: Standardized for a 150N.m torque input per bolt, creating a rigid, positive lock that completely bypasses the unpredictable snapping risks associated with tension-actuated automatic lever wire grips.

• UHV / EHV Power Transmission Construction: Tension stringing, sagging, and anchoring of massive bundled conductors on mega-grid cross-country towers.
• Long-Span Utility Crossings: High-tension holding during river-spanning, valley-spanning, or highway-crossing overhead wire placements.
• Substation Mega-Conductor Installation: Rigid temporary anchorage for terminal line dead-ends.

Large conductors above Φ25mm have extremely stiff, multi-layered aluminum strands wrapped around a steel core. Standard rigid one-piece clamps can only make contact at slight high spots along the uneven wire surface, leading to severe localized pressure that crushes the outer aluminum shell or causes slipping. The multi-segment design allows each section to clamp down independently, ensuring uniform pressure across the entire length of the clamp.

By using a multi-bolt configuration tightened to 150N.m, the clamp creates a steady, predictable static friction force. This high compression is evenly distributed across 9 to 15 segments, securing both the external aluminum shell and the interior high-strength steel core as a single unit, which effectively eliminates slippage and line stripping.

Yes. Every bolt in the array is forged from high-tensile alloy steel and calibrated for standard heavy-duty utility impact wrenches, hydraulic torque tools, or manual heavy-duty ratchets. This ensures lineworkers can quickly and safely reach the required 150N.m threshold during high-altitude operations.
