Discussion on Solving down Leading of OPGW under Framework with Insulation

OPGW shall be lightening-proof and grounded after entering transformer station framework. Due to problems existing in grounding, optical cable is discharged and breaks down. For such a purpose, the Author investigates several down leading and grounding methods on OPGW framework, by comparing and analyzing, and proposes the “framework down leading insulation not grounded”. This method adopts framework insulation down leading not grounded and grounded reinforced on terminal tower to solve the issue of framework grounding and result in sound effects.
