Direct Tension Clamp

Direct Tension Clamp – Heavy-Duty Dead-End for Overhead Power Conductors

Direct tension clamps are high-strength, direct-mount anchoring fittings designed to directly attach and tension overhead power conductors (ACSR, AAAC, aluminum, copper) without intermediate hardware. Ideal for dead-end, angle, and through applications in 11kV–33kV distribution lines and transmission networks, where direct, rigid mounting to poles/towers is required.

Key Features

• ✅ Direct Mount Design: No brackets/hooks needed; bolts directly to pole flanges, cross-arms, or tower structures.

• ✅ Heavy-Duty Construction: Body in high-grade aluminum alloy or ductile iron; bolts in hot-dip galvanized steel (HDG)or SS304.

• ✅ Ultra-High Tensile Strength: 20–60kN minimum breaking load (MBL)for medium to heavy-span power lines.

• ✅ Secure Conductor Grip: Precision-machined serrations; grip strength ≥95% of conductor rated tensile strength (RTS).

• ✅ Corrosion & Weather Resistant: HDG/electroplated finish; anti-aging, UV-stabilized; service life ≥30 years.

• ✅ Wide Conductor Compatibility: Fits 8–40mm diameterACSR, AAAC, aluminum, and copper conductors.

• ✅ High-Voltage Compliant: Meets IEC 61284, CE & RoHS certified; suitable for 11kV–33kV lines.

• ✅ Vibration & Fatigue Resistant: Withstands wind-induced vibration and ice loads; tested for >10⁷ cycles.
