ST Device Wire Clamp

ST Series Bolted Copper Equipment Clamps are heavy-duty T2 copper terminal connectors designed for secure, high-conductivity connections between power cables and electrical equipment (transformers, switchgear, breakers) in substations and industrial systems. Featuring bolted compression, precision machining, and optional tin-plating, they ensure low resistance, reliable contact, and long-term durability for LV/MV power connections.

Key Features

• ✅ High-Grade T2 Copper: ≥99.9% pure copper, excellent conductivity, low contact resistance

• ✅ Bolted Compression Design: 2–4 bolt configuration for uniform pressure, strong grip

• ✅ Optional Tin-Plating: Anti-oxidation, anti-corrosion, easy soldering (optional)

• ✅ Precision Machining: Smooth surface, accurate dimensions, perfect fit

• ✅ High Mechanical Strength: Withstands vibration and thermal cycling

• ✅ Wide Size Range: 35–400 mm² for copper cables (stranded, solid)

• ✅ Standard Angles: 0° (A), 30° (B), 90° (C) for flexible installation
