Property Specification
Type: Bi-Metallic Tubular Connector / Pin Terminal (GTLZ Series)
Features: Produced via a solid friction-welding process uniting electrical-grade aluminium (≥ 99.5%) and high-purity copper (≥ 99.9%). Engineered for compatibility with pre-rounded sector-shaped conductors. The interior aluminium barrel is pre-loaded with neutral contact grease and fitted with a protective cap to guard against contamination and oxidation.
Applications: Ideal for non-tension screwed connections, enabling secure transitions from aluminium conductors into copper terminal clamps and equipment interfaces.
