T-clamp refers to the hardware used to connect the conductor with the branch line to transfer electrical load. High voltage transmission line is an important part of power grid, which connects substations and transmits power. In the design of transmission lines, we can see the connection mode of line T-connection. T-connection lines are two lines with different spatial levels connected by short circuit at the intersection of the same voltage level. Substation A supplies power to substations B and C at the same time. The advantages are that investment is reduced and a substation bay is used less. This way of connecting another line from the main line is vividly called "T" connection mode, This outgoing point is called "T contact".
T-type clamp is mainly used for overhead circuit lines or substations, which leads down current branches on the main bus in a "T" mode. There are two types: bolt type and compression type. For small section conductors, the so-called T-type connection can also be used with parallel groove clamps or clamped elliptical splicing tubes.
TL series single conductor T-clamp is a kind of T-clamp used to connect branch conductor to the trunk conductor, including: T-shaped substrate, with trunk groove in the transverse part, with wire holes in the longitudinal part, metal linings are set on the inner wall of trunk groove and branch hole, and the two metal linings are connected as a whole, and the upper surface of the longitudinal part of the substrate is threaded with branch conductor compression screws; Trunk slot cover is inserted with trunk slot, and its upper surface is screwed with dry conductor compression screw; The T-shaped upper cover is buckled with the T-shaped base. When connecting, only the simple work of fastening screws is needed, which saves time and labor; The branch wire and the dry wire are in close contact with the metal lining through the compression screw, and the contact area is large, so the connection is safe and reliable.
