Advantages of T-bolt clamps
Advantages
●Designed Specifically for Copper-Aluminum Transitions
One end is copper and the other is aluminum, completely eliminating the electrochemical corrosion and overheating issues caused by direct copper-aluminum connections.
●T-Connection Without Cutting Wires, Fast Installation
The main line remains intact; branches are connected directly and secured with bolts, ensuring simple installation and high on-site efficiency.
●Reliable Contact and Stable Conductivity
The serrated contact surface provides a large contact area, uniform clamping force, low contact resistance, high current-carrying capacity, and minimal heat generation.
●Compatible with Cables of Same or Different Sizes
Can be used even when the main and branch lines have different diameters, offering high versatility.
●High Mechanical Strength and Vibration Resistance
The bolt-locking structure resists wind sway and vibration, preventing the cables from slipping or loosening.
●Corrosion-Resistant, Durable, and Reusable
The main body is treated for corrosion resistance, ensuring a long service life outdoors; can be disassembled for maintenance and reused.
Typical Applications
●T-connection of aluminum conductors (main line) to copper leads (branch line), such as wiring for transformers, switchgear, and meter boxes
●T-connections, branching, and jumpers for copper-aluminum conductors in 10kV and below distribution lines
●T-type connections for copper-aluminum leads on the low-voltage side of substation transformers
●Copper-to-aluminum transition and branching in rural, urban, and industrial park power lines
●Suitable for T-connections between steel-core aluminum stranded wire, aluminum stranded wire, and copper stranded wire or copper cable

FAQ
Q: What is the difference between TL-type T-clamps and standard T-clamps?
A: TL-type T-clamps are copper-to-aluminum transition clamps used to connect aluminum wires to copper wires; standard T-clamps are only suitable for wires of the same material.
Q: Why must TL-type clamps be used when connecting aluminum wires to copper wires?
A: Direct contact between copper and aluminum causes electrochemical corrosion, leading to heat generation and burning. TL-type clamps effectively prevent this.
Q: Can TL-type clamps be used when the main conductor is copper?
A: Not recommended. For copper-to-copper connections, use copper T-type clamps; TL-type clamps are specifically designed for aluminum main conductors paired with copper branch conductors.
Q: Can TL-type clamps be used if there is a significant difference in wire gauge between the main and branch conductors?
A: Yes, as long as the wire gauges fall within the range specified for the clamp model.
Q: What should I pay attention to during installation?
A: Clean the oxidation layer from the conductors, tighten the bolts evenly, ensure the copper and aluminum contact surfaces are aligned, and install an insulating cover for outdoor use.
Q: Can TL clamps be reused?
A: They can be disassembled and reused, but you must inspect the copper-aluminum contact surfaces and ensure the teeth are free of deformation and corrosion before reuse.
