🔶 TRANSFORMER COPPER STUDS

Conex Transformer Copper Studs are manufactured from high-conductivity electrolytic copper and used for bushing rods, winding leads, tap connections, and transformer terminal assemblies. These studs are CNC-machined and roll-threaded for high torque strength, vibration resistance, and long-term stability.

Copper Material Grades Used

✔ ETP Copper – C11000

• Conductivity: 101% IACS

• Cu ≥ 99.90%

• Best for: Standard transformer studs

• Features: High conductivity, cost-effective, easy plating

✔ OFC / OFHC Copper – C10200

• Oxygen-free copper

• Conductivity: 101–102% IACS

• Best for: High-current, critical connectors

• Benefits: No hydrogen embrittlement, highest purity

✔ Silver-Bearing Copper – C10700

• Used in high-temperature, high-load applications

• Better softening resistance at elevated temperatures

Coating Options:
Tin, Nickel, Silver plating available.

🟫 BRONZE TRANSFORMER TERMINALS

Bronze transformer terminals are engineered for high mechanical load and thermal cycling environments. Manufactured from premium Tin Bronze, Gunmetal, and Aluminium Bronze alloys, they provide outstanding performance in HV/LV transformer connections.

Bronze Material Grades

✔ Aluminium Bronze

✔ Tin Bronze / Gunmetal

✔ Phosphor Bronze

• C51000 (CuSn5)

• C52100 (CuSn8)

• C54400 (Pb-bearing phosphor bronze)

Ideal for fatigue-resistant terminals & spring-loaded clamps.

🟨 BRASS TRANSFORMER TERMINALS

Brass transformer terminals are used where good conductivity, easy machining, and economical cost are required. Suitable for LV transformers, control panels & switchgear.

Brass Grades
