Threading is the work of connecting the insulated conductor from the distribution box through the distribution pipe to the electrical equipment. In order not to damage the conductor, air blowing or cloth should be used to clean the inside of the pipe before threading, then talcum powder should be blown in, and the protective sleeve should be installed at the end.

 

 

 

YCB扁電纜,導(dǎo)線穿管一般用鋼絲引入，當(dāng)管路較長(zhǎng)或者彎頭較多的時(shí)候，應(yīng)一端有人接線，另一端有人送線，而且兩人動(dòng)作要協(xié)調(diào)，穿入館內(nèi)的導(dǎo)線應(yīng)平行，不要相互纏繞。

 

When the pipeline is long or there are many elbows, there should be someone at one end for wiring and someone at the other end for wire feeding, and the two people should coordinate their actions. The wires going into the museum should be parallel and not intertwined.

 

 

 

為了使穿在導(dǎo)管內(nèi)的線路安全可靠地工作，凡是同一回路的導(dǎo)線必須穿在同一根管內(nèi)，而不同電壓的回路，禁止同管敷設(shè)，管內(nèi)導(dǎo)線不許有接頭。

 

In order to make the line in the conduit work safely and reliably, all the wires in the same circuit must be in the same pipe, while the circuits with different voltages are not allowed to be laid in the same pipe, and the wires in the pipe are not allowed to have joints.
