LILO of 220kV Ranasan-Karamsad to 220kV Kanbha GIS 480 2

(1) Existing OPGW at Loc no 195 shall be open & OPGW shall be back pull upto Existing Loc no 191 and restringing shall be done between existing loc no 191 to proposed Loc no DD type & Proposed MD type tower and

spliced with FOAC cable from Kanbha SS.

(2) New OPGW with approx length 1100 mtr stringing work to be done between Proposed MD type tower & Loc no

(3) Around 800 mtr of OPGW will be avilable spare after back pulling & same shall be tested for OTDR & credited to Nadiad Store in co-ordination with EE(Telecom) Ranasan

(4) After completion of this arrangement work of FOAC & OPGW, for above LILO work of 220kV Ranasan-Karamsad Lilo Kanbha Line , it shall be tested for End to End test & trace report shall be submitted for approval.

Following points are important from work execution perspective, same may please be noted.

i) Fiber optic approach cable (FOAC) shall be laid with 220kV cable system strictly as per approved method of construction i.e MOC. Each run of FOAC shall be of continuous length, no in between splicing is allowed.

ii) Two to Three rings of extra loop length shall be kept buried underground at foot of both end termination tower after laying FOAC cable with 220kV cable as per MOC.

iii) FOAC cable length remain outside and above the ground level shall be 2 times the height of each termination tower at both end. Each run of FOAC cable coming out after laying in underground section should be

brought up to third cross arm of termination tower after passing it through HDPE pipes and properly tying up with tower. Also, each run of FOAC cable shall be terminated in individual joint box on each termination

iv) Balance length of each FOAC cable (i.e. Approximately half of tower height) after bringing out the FOAC cable above from ground level and up to third cross arm of termination tower, it shall be managed in rings

properly with fixing clamp arrangement to hold up it on end termination tower.

v) As per standard format "End to End test.pdf" in , after laying FOAC cable, each length shall be tested for end to end test using power meter and OTDR. Original copy of Test report duly sealed and signed with date,

name & designation of testing person, executing contractor and witnessing officer one each from telecom as well as TR/Const. nominated from respective EE(Telecom) and EE(TR)/EE(const.) respectively, shall be

submitted to under signed & one copy to respective telecom unit, invariably without fail

vi) Only after getting clearance on validity of test report submitted to this office, filed officer will take further necessary action on commercial part.

vii) DRS (Data requirement sheet) and drawing approval shall be taken for FOAC & joint box before kick starting any erection activity. The work executing contractor must have to do correspondence on eamil to concern

EE (Const.) with copy to project & engineering department, corporate office, GETCO for necessary concurrence and intimation about to start erection/laying.
