T-connector is a fitting used to connect main conductors and branch lines in order to transmit electrical loads and withstand certain mechanical loads. T-connector clamps are typically divided into bolted and compression types for connecting either the main conductor or the down-lead.
High-voltage transmission lines serve as pathways for connecting substations and transmitting electricity, playing a vital role in the power grid. In the design of transmission lines, we often encounter the T-joint connection method, where T-connector connections are used to link lines of different spatial levels at the intersection of two lines of the same voltage level. This allows power to be supplied simultaneously from Substation A to Substations B and C, with the advantage of reducing investment and eliminating the need for an extra substation interval. The method of branching out another line from the main line is figuratively called the "T" connection method, and the point where the branch line is taken off is referred to as the "T-joint point."
