Description

technical field

[0001] The invention relates to an optical cable quick transfer box mainly used in OPGW optical cable transfer. Background technique

[0002] OPGW optical cable (Optical Fiber Composite Overhead Ground Wire, also known as optical fiber composite overhead ground wire), the optical fiber cable is composed of metal and optical fiber, and the optical fiber is placed in the ground wire of the overhead high-voltage transmission line to build an optical fiber communication network on the transmission line , this structure makes the cable have dual functions of ground wire and communication.

[0003] It can be seen from the above that the OPGW optical cable itself contains ground wires and communication functions. It is erected on the iron tower and is easy to guide lightning. Another kind of all-dielectric self-supporting metal-free optical cable (also known as ADSS optical cable) core fusion, through which the optical fiber signal is introduced into the substation...

Embodiment Construction

[0028] Referring to the accompanying drawings, the optical cable quick transfer box of the present invention includes a base 1, an optical fiber splicing tray 3 mounted on the base 1 through a bracket 2, and a buckle cover 4 packaged on the base 1 and incorporating the optical fiber splicing tray 3 therein. The incoming line 5 and the optical cable outgoing line 6 are fixed on the base 1 respectively. The optical fiber flange fixing frame 7 is also installed on the base 1. The optical fiber fusion splicing tray 3 is fixed on the top of the bracket 2, and the optical fiber flange fixing frame 7 is fixed on the bracket. 2 middle. A plurality of optical fiber flanges 8 are installed on the optical fiber flange fixing frame 7 . The base 1 is equipped with a vertically arranged incoming line protection tube 9 and an outgoing line protection tube 10 . The cable inlet 5 is installed in the inlet protection tube 9 and after passing through the inlet and outlet protection tube 9, a pl...
