> Combined elbow pipe
The body of elbow pipe is made up of two detachable parts. During installation and operation, first let wire enter the fastening caps at both sides of the body of elbow pipe, then wire and operate. At last, bind two pieces of elbow pipe body together and put on the fastening caps. It has the character of easy installation, which is convenient for the check and replacement of circuit in the future.
>Combined Tee joint
Its main structure, function and character are same as those of combined elbow pipe
>Switch box
The mould of switch box is processed b digital-controlled machine tool to guarantee the precision of product. For example, the size of go-between hole on the switch box is very precise, which may be connected closely with tooth buckle and prevent concrete from entering the switch box. Besides, Liutong Company has modified the process on the screw joint between box cover and box body. The iron slice of fastening screw interface is fastened inversely into the box body and closely connects with the body, which also can prevent concrete from entering the switch box during constructing.
>Using switch box together with tooth buckle
There are holes in five directions for connecting with line and make the arrangement of line more flexible. Inner and outer teeth of the tooth buckle are fixed on the body of switch box and can be connected with different go-between tubes. When wire is connected with switch box, the insulation layer of wire won't be hurt to guarantee safety.
>Simple elbow pipe
It is mainly used to connect go-between tubes at the corner of wall or curved places. Since the product of Type I adopts new process, the inner side has no burr and obstacle, as a result, the insulation layer of wire is protected well and with less resistance. The difference between Type I and type II is that the middle part of Type I is round-shape but in Type II is rectangle.
>Light head box
It is applicable to the wiring between wire go-between tubes on the ceiling and can effectively protect wiring terminal and it is convenient for checking and maintaining line.
>Open wire box
When electric circuit is not required to fix in wall, the open wire box is adopted to connect between lines. It can effectively protect wiring terminal and is convenient for checking and repairing line.
