Cluster Tension Clamp

Cluster Tension Clamp – Insulated Dead-End for 2/4-Core ABC Cables

Cluster tension clamps (also known as bundled conductor strain clamps) are wedge-type, self-tightening anchoring fittings designed specifically for 2-core or 4-core aerial bundled cables (ABC/LV-ABC). Ideal for low-voltage (≤1kV) overhead distribution lines, providing secure dead-end tensioning without stripping cable insulation.

Key Features

• ✅ 2/4-Core Compatibility: Fits both 2-core and 4-core bundled cables(16–240mm² cross-section).

• ✅ No Insulation Stripping: Unique parallel-groove design grips cables firmly without removing insulation, saving installation time.

• ✅ Wedge Self-Tightening Structure: Integrated wedge mechanism tightens automatically under tension—no retightening needed.

• ✅ High-Strength & Insulated: Body in UV-stabilized PA66 GFor aluminum alloy; internal wedges in hardened anti-slip thermoplastic.

• ✅ Heavy-Duty Tensile Strength: 5–20kN minimum breaking load (MBL)for low-voltage distribution spans.

• ✅ Weather & UV Resistant: Anti-aging, UV-stabilized materials; service life ≥25 years.

• ✅ Tool-Free Installation: Hand-operated wedge insertion; install in seconds without hydraulic tools.

• ✅ Vibration & Fatigue Resistant: Withstands wind vibration and thermal cycling; tested for >10⁷ cycles.
