Product Introduction
DT-120 Copper Tubular Lugs
As a premier heavy duty copper lug manufacturer China, Jinkaite produces the DT-120 tin-plated copper cable terminal. Expertly designed for crimped terminations of 120mm² copper cables within low-voltage power distribution systems, this robust fitting ensures a tight, gap-free fit under hydraulic compression, protecting electrical joints from oxidation in transformers, switchgears, and box-type substations.
Designed for 120mm² copper cables, this lug is engineered for crimped terminations in low-voltage power distribution systems, suitable for connecting cable ends within distribution cabinets, transformers, and box-type substations. Manufactured from high-purity copper via a crimping process, it features a precise structure and ensures secure, reliable connections. Easy to install and crimp, it is a standard component for connecting cables to electrical equipment.

Detailed technical parameters
DT-120 Copper Tubular Lugs
Inner and Outer Diameters: The inner diameter accommodates the insertion of a 120mm² copper cable; the dimensions are compatible with standard crimping dies, ensuring a tight, gap-free fit after crimping.
Total Length and Effective Barrel Length: Ensures sufficient cable insertion depth and adequate contact area, thereby minimizing contact resistance at the connection point.
Mounting Hole Diameter: Compatible with standard fastening bolts, allowing for direct securement to equipment terminal blocks.
Tensile Strength: Withstands a 7.2kN tensile force without loosening after crimping, meeting requirements for long-term mechanical stress and cable tension.
Weight: Lightweight design facilitates installation and cable routing within compact cabinets.
Product Features
Technical Features of DT-120 Copper Tubular Lugs:
High-Purity Electrolytic Copper: Formed from a single piece of 99.9% high-purity electrolytic copper tube via seamless stamping and cold-extrusion forging, ensuring minimum electrical resistance and zero thermal hotspots during high-current flow.
Electro-Tin Plated Corrosion Shield: The entire surface of the tin-plated copper cable terminal undergoes strict electro-tinning, preventing copper oxidation, mitigating moisture-induced tarnishing, and safely isolating galvanic corrosion in humid environments.
Precision CNC Tapped Mounting Holes: The cable insertion barrel and mounting hole dimensions (Ø, D, d, L) are precision-punched and chamfered by CNC equipment, perfectly matching standardized international dies from DT-35 to DT-120 mm² heavy duty compression terminals.
Unmatched Tensile & Mechanical Strength: Features an optimized effective barrel length (L₁) that withstands a grip strength/tensile load of 7.2 KN, preventing wire loose-outs and fulfilling utility grid requirements for long-term mechanical stress.
