Pin Type Bimetallic Lugs

Our Pin Type Bimetallic Lugs are heavy-duty electrical connectors engineered to bridge aluminum conductors with copper terminals or switchgears safely and efficiently. By combining high-grade aluminum with a solid copper pin, these lugs eliminate galvanic corrosion caused by direct contact between dissimilar metals. Designed for seamless insertion into tunnel-type terminal blocks, circuit breakers, and control gear, they ensure optimal electrical conductivity, low resistance, and long-term connection stability.

Key Features & Technical Highlights:

• Bi-Metallic Junction Protection: Manufactured using advanced friction-welding techniques to join high-conductivity aluminum with premium copper, preventing electrochemical oxidation and thermal expansion issues.
• Pin Type Terminal Design: Features a solid pin contact profile specifically shaped for secure, precise fitting into compact terminal blocks, contactors, relays, and MCBs.
• High Conductivity & Efficiency: Low contact resistance reduces voltage drops, power loss, and excessive heat generation under continuous heavy loads.
• Corrosion & Oxidation Resistance: Pre-filled with jointing compound in the barrel end to protect aluminum conductors against atmospheric moisture and oxidation.
• Vibration-Proof & Secure Crimp: Designed with a uniform barrel wall thickness for firm compression crimping, ensuring high tensile strength and cable retention.
