The DongCheng HD116118 18" (450mm) Industrial Cable Cutter is the largest and most powerful manual cable cutter in the lineup, engineered for electrical substations, heavy industrial infrastructure, and utility contracting. Forged from high-grade 55# carbon steel, the entire tool body undergoes structural heat treatment, while the cutting edges are precision induction-quenched to deliver edge retention.

Its extended 450mm dual tubular steel lever arms provide massive mechanical advantage, cleanly cutting large copper and aluminum cables up to 150mm² without crushing the wire strands. Specifically engineered for non-ferrous electrical cables, it must not be used on ACSR, wire rope, or steel self-supporting strand. Fitted with comfortable ergonomic grip handles and packaged in a protective paper box.

Key Features

• Maximum 150mm² Cutting Capacity: Slices through large electrical mains, multi-conductor feeders, and heavy commercial power lines.
• Induction-Quenched Cutting Edges: Hardened cutting edges resist dulling, chipping, and wear across extensive use.
• High-Leverage 450mm (18") Tubular Arms: Delivers maximum compound cutting power to handle thick conductors with reduced manual exertion.
• Heat-Treated 55# Carbon Steel Body: Structural hardening prevents arm flexing and maintains jaw alignment under heavy loads.
• Optimized for Non-Ferrous Cable: Designed specifically for copper and aluminum conductors (not for ACSR or steel wire rope).
• Protective Paper Box: Delivered in a durable storage box for jobsite transport.

Applications

• Slicing heavy commercial and industrial copper and aluminum transmission cables
• Utility substation maintenance, high-voltage distribution lines, and switchyard construction
• Heavy shipyard electrical installations, mass transit power systems, and infrastructure wiring
• Large industrial plant power feed preparation and high-capacity electrical setups
