Large Capacity OPGW

Construction of new and old transmission lines with large and super large cores and “T” connection lines.

The fiber capacity of OPGW can be increased by 50% -100% with the same structure, up to 192 cores;
With the optimization of the OPGW structure, the lightning resistance level of the line can be effectively improved;
Solve the technical difficulties of fiber optic expansion and renovation of new and old lines, and passed the appraisal in 2020.

IEC 60794-4-10	Aerial optical cables along electrical power lines – Family specification for OPGW
IEEE1138-2009	IEEE Standard for testing and performance for optical ground wire (OPGW) for use on electric utility power lines

(1)Stranded type:Fiber core capacity can be increased 1 time or 2 times more after using double optical units and three optical units.

(2)Central Type:Fiber core capacity can be increased 1 time more after using the 1+7 irregular design.

(3)By using 200um small-diameter optical fiber,the optical fiber capacity can be increased by at least 50%,and the number of cores can reach 168 and 192.
