Copper Terminal Block

The copper distribution block is a metal connector device encapsulated in insulating plastic.  The main body is made of T2 copper, and the surface is tin-plated to enhance oxidation resistance. Some products are equipped with a screw fastening structure. Its main function is to achieve low-resistance conduction through crimping/welding, and it uses both mechanical crimping and bolt fastening for improved anti-loosening performance. The corrosion-resistant and sealing rating can reach IP68. Product types include DT oil-filled type, DTG tube crimping type, and SC double-hole type, suitable for cables of 10 square millimeters and above. For photovoltaic applications, copper-aluminum transition terminals should be used to prevent electrochemical corrosion.

It is suitable for connecting a large number of wires. In the power industry, there are specialized terminal blocks and terminal boxes, which are full of terminal connectors, including single-layer, double-layer, current, voltage, ordinary, and disconnectable types. A certain crimping area is necessary to ensure reliable contact and to ensure that sufficient current can pass through.
