Advantages of Terminal Blocks
ApplicationsConnecting copper cables to copper busbars, copper switches, and copper terminals on transformers.
Termination crimping of copper conductors inside distribution cabinets, distribution boxes, and control cabinets.
Copper cable wiring for equipment such as motors, inverters, and UPS systems.
Low-voltage distribution (10 kV and below), industrial control, photovoltaic, and wind power systems.
Advantages of DT Copper Terminals
Excellent conductivity: Made of T2 pure copper, featuring low resistivity, high current-carrying capacity, and minimal heat generation.
Reliable crimping: Tube-shaped/rod-shaped design ensures secure wire crimping and stable contact resistance.
Corrosion-resistant and durable: Tin-plated or silver-plated surfaces provide oxidation resistance, rust prevention, and a long service life.
Easy Installation: Compatible with standard crimping pliers; single-hole or double-hole mounting ensures quick installation.
Comprehensive Range: Covers 10–630 mm² to accommodate all types of copper cables.
High Versatility: Compatible with copper busbars, circuit breakers, switches, electricity meters, and other copper equipment.
Advantages of DTL Copper-Aluminum Terminals
Copper-Aluminum Transition: One end is copper and the other is aluminum, eliminating the issue of electrochemical corrosion associated with direct copper-aluminum connections.
Secure Welding: Friction welding or brazing processes ensure dense welds, high strength, and stable conductivity.
Compatibility with Aluminum Wires: The aluminum end accommodates aluminum stranded wire and aluminum cables, while the copper end connects to copper equipment.
High Corrosion Resistance: The copper-aluminum junction is well-sealed, resistant to salt spray and humidity, and durable for outdoor use.
Simple Installation: Crimping + bolt fastening; no special treatment required, ensuring efficient installation.
Complete Range of Sizes: 16–630 mm², compatible with mainstream aluminum cables and copper equipment connections.
ApplicationsTransition connections between aluminum cables/stranded wires and copper busbars, copper circuit breakers, electricity meters, and the copper terminals of transformers.
Connecting aluminum wires to copper equipment in rural and urban power grids, as well as outdoor overhead lines.
Transitioning from aluminum cables to copper equipment in photovoltaic, wind power, and industrial plant power distribution systems.
Prevents overheating, corrosion, and wire breakage caused by direct contact between copper and aluminum.

FAQ
Q: What is the difference between DT and DTL terminals?
A: DT is a pure copper terminal used to connect copper cables to copper equipment;
DTL is a copper-to-aluminum transition terminal, with one end made of copper and the other of aluminum, used to connect aluminum cables to copper equipment.
Q: Why can’t DT terminals be used directly with aluminum wires?
A: Direct crimping of copper and aluminum causes electrochemical corrosion, which over time leads to overheating, loosening, and burning of the terminals. DTL copper-to-aluminum transition terminals must be used.
Q: Can DTL terminals be used with copper wires?
A: Yes, but it is not recommended. DT terminals provide better conductivity and lower cost for copper wires, while DTL terminals are specifically designed for aluminum wires.
Q: How do I select the correct model?
A: Select based on cable cross-section:
Copper cable → Select DT-XX
Aluminum cable → Select DTL-XX
Example: Use DT-50 for 50mm² copper wire and DTL-50 for aluminum wire.
Q: Are DTL copper-to-aluminum transition terminals prone to breaking?
A: Genuine products use friction welding or brazing, which provides high bond strength; they will not break under normal use.
Q: What should I pay attention to during crimping?
A: Ensure the wire is stripped to the correct length; the copper core must not be exposed.
Use crimping pliers of the appropriate size and crimp firmly.
Position the bolt holes for easy installation.
