How to represent the cable T connection, and what is the cable T box?

In high-voltage power supply, "T" connection refers to the indirect supply of a line from the line supplied by Party A to Party B to supply power to third party C; Since it is connected from the line that supplies power to others, from the "look" of power supply A, this line is quite a two users, Party B and Party C.

It is precisely because it is connected from the middle of the line "T" that its operation is not affected by the operation mode of Party B; The reliability of power supply is the same as that of Party B; At the same time, because they are independently powered, the protection setting and setting are relatively simple. In the low-voltage line, the "T" connection is the branch connection on the main line.

Add a bold dot between horizontal and vertical.

"Cable T box" is the iron box used to protect the joint when making branch joints on the main cable

For the installation of cable T junction box, according to its half-circumference set of surface-mounted junction box installation subhead, the main material cost of the box is charged separately.

Regardless of whether the branch line is a cable or a wire, its joints are set of the user's internal dry-clad copper core cable head system stability and quantity 1 (not divided into three-core, four-core, five-core cables).

Cable T-junction box: It is mainly used for the "T" shaped distribution connection when the cable cannot be cut off in construction and industrial electrical equipment.

In the past, the "T" shape of the conductor was usually made by stripping the cable insulation, winding the branch conductor around the trunk wire, and wrapping it with an insulating cloth. The hazards of this wiring method are poor reliability and large contact resistance, which is very easy to cause electrical accidents; Moreover, when the cross-section of the branch wire is 10mm*mm, it is difficult to operate by manual winding.

The "electric BAI cable T box" is the special iron box used to protect the DAO position of the joint when making the DU branch ZHI joint on the main cable, and this kind of installation occurs.

The quota can be applied as follows: For the installation of the cable T junction box, the installation sub-item of the surface-mounted junction box shall be set according to its half-circumference, and the main material cost of the box shall be charged separately. Regardless of whether the branch line is a cable or a wire, its joints are set of the user's internal dry-clad copper core cable head system stability and quantity 1 (not divided into three cores, four cores, and five cores.

The T-terminal of the cable is actually the branch of the cable, and the common ones are branch cables, insulation piercing clamp branches, and terminal branches.

This T terminal is the branch of the power supply, which is commonly known as taking power from the main cable.
