Suspension Clamps are explicitly engineered to suspend and support low-voltage Aerial Bundled Conductor (A.B.C.) bundles on straight-run intermediate poles within fully supported (self-supporting) networks. Designed without the need for a separate messenger wire, this clamp features an expansive cradle that simultaneously carries and protects all four insulated phase conductors. It provides a secure structural hold against wind-induced vibrations and line angles without putting concentrated stress on the cables’ outer dielectric coats.

Features
4-Core Unified Suspension Cradle
Outfitted with an extra-wide, smooth-curved parallel channel designed to accommodate and support all four bundled insulated conductors simultaneously, ensuring perfectly balanced vertical weight distribution.
Tool-Free Wing-Nut Locking
Features an integrated high-torque wing nut or ergonomic hand-knob assembly. This allows linesmen to firmly clamp and lock the cable bundle into the housing manually, completely eliminating the need for specialized wrenches overhead.
Dielectric Polymeric Cushioning
The internal clamping pads are precision-molded from UV-stabilized, glass-fiber reinforced polymer. The smooth lining dampens mechanical sway while completely eliminating point-load concentration or insulation abrasion.
High-Strength Articulated Link
Designed with a robust mechanical connection eye or integrated linkage that allows a wide degree of multi-directional vertical swinging, reducing dynamic fatigue stress on both the pole bracket and the conductors.
Implementation Instructions
Step 1: Cable Placement & Sorting
Loosen the tool-free wing nut of the suspension clamp to fully open the upper movable jaw. Group the four insulated conductors of the ABC bundle neatly and place them flat inside the lower cradle channel.
Step 2: Tool-less Hand Locking
Push down the upper clamping pad. Manually spin and tighten the integrated wing nut firmly until the internal jaws compress uniformly around the outer jackets of the bundle, securing it against sliding.
Step 3: Bracket Hanging Execution
Hook the suspension link or eyelet directly onto the designated pole suspension bracket. Verify that the clamp assembly can swing freely and that the bundle maintains its correct routing sag profile.
Step 4: Vertical Sway & Live-Line Safe Handling
Because the entire housing and internal gripping pads are molded from non-conductive, premium dielectric polymers, this suspension clamp is exceptionally safe for handling in close proximity to live lines (hot-line handling). However, linesmen must ensure that the cable bundle is properly supported by temporary cable stringing rollers during the initial pulling process before placing the full deadweight onto the final clamp cradle.
Industrial Engineering & Standards
High-end pole-line support hardware engineered and verified to maintain grid structural alignment under relentless environmental weathering:
- Advanced Structural Materials: The outer structural body is forged from corrosion-free aluminum alloy or ultra-rugged engineered thermoplastics, paired with hot-dip galvanized steel links for maximum load support.
- Rigid Utility Standard Compliance: Thoroughly batch-tested and fully qualified to meet the strict vertical load, slip-resistance, and climatic aging requirements of NF C 33-042 and EN 50483-3 standards.
- Zero Thermal Creep: All structural polymer components retain exceptional tensile elasticity and high-fatigue retention across a wide thermal spectrum, resisting both extreme Arctic freeze and intense tropical UV degradation.
