VDE Insulated Tools — Built for the Line, Proven Under Pressure
Professional-grade insulated tools that go where others won’t — and come back safe.
Dielectric Safety
All units per batch pass 10,000V dielectric test (50Hz, 1 min) by independent labs, no random sampling. Test reports available for verification. We go beyond IEC/EN 60900.
15 Patents
15 patents cover key structures and processes including jaw, measuring unit, safety lock and coating. Featuring a world-first built-in cable cutting depth measuring device. All patents verifiable via CNIPA.
Ultra-wearproof Insulating Coating
Patented coating improves insulation wear resistance by 40%. Dielectric performance remains stable after 10,000 plug cycles, prolonging service life and reducing costs.
Low Shear Resistance
Optimized jaw curve reduces shear force by 30%, delivering neat cuts and less wire damage. Relieves fatigue during prolonged operation.
Fast Delivery
MOQ: 50 sets per spec (vs 200 sets industry average). Delivery: 15-25 days. Full OEM/ODM available; logos, colors and packaging customizable.
