DTL-S Double Hole Cable Lug Bimetal Connector

Bimetallic Lugs are mostly useful where an aluminum cable has to be terminated by a copper bus bar or copper contact. If Cable Lugs of only copper or aluminum are used , a galvanic action occurs due to dissimilar contact. The use of bimetallic lugs thus ensures a technically sound and durable joint. The Aluminum barrel is friction welded to the copper palm thereby achieving the best possible transition between barrel & palm.

Product Overview


The DTL-S Double Hole Cable Lug Bimetal Connector is specifically engineered for the power industry, effectively bridging the connection between copper and aluminum wires. This connector features a conductive aluminum barrel with 60% IACS and a copper palm rated at 97% IACS, ensuring superior conductivity. With a final metal state that is fully annealed and a jointing method of friction welding, the DTL-S provides mechanical strength and durability. Ranging from 16 Sqmm to 500 Sqmm, this connector is versatile for various applications, including MV terminations and LV connections on bus bars.

Exceptional Conductivity and Durability

The DTL-S Double Hole Cable Lug features a unique bimetallic construction that combines copper and aluminum, delivering outstanding conductivity and corrosion resistance. The aluminum barrel has a conductivity rating of 60% IACS, while the copper palm boasts a remarkable 97% IACS. This ensures reliable circuit transmission, making it ideal for use in substations, transmission lines, and power equipment. The fully annealed final metal state enhances the flexibility and strength of the connector, allowing it to withstand high electrical loads without compromising performance.

Innovative Jointing Method

Utilizing friction welding as its jointing method, the DTL-S connector ensures a strong bond between the copper and aluminum components. This technique not only enhances the mechanical strength of the joint but also minimizes the risk of failure under electrical loads. The PVC insulation provided at the terminals offers exceptional dielectric strength, safeguarding the connection from electrical hazards. Additionally, the shock-proof or bell-mouthed entry into the wire barrel allows for easy and efficient conductor entry, streamlining the installation process.

Wide Range of Applications

The DTL-S Double Hole Cable Lug is designed for a variety of applications, making it an essential component in the electrical power industry. Its versatility allows for use in MV terminations and LV connections on bus bars, catering to diverse wiring needs. The design prioritizes safety and cost-effectiveness, making it a practical choice for professionals in the field. The electro-tinned copper components comply with BS standards, ensuring protection against corrosion and oxidation.
