METHOD OF STRINGING CONDUCTORS & OPGW GENERAL PURPOSE Purpose of this stringing work method is to guide all the crews / workers who will be involved instringing earth wire, optic cable, conductor and in installation of fittings, so that the works canbe done properly with good quality and safely. Therefore before the work start for everysequence, the crews must ensure about their duties agenda, target of work, SCOPE OF WORK The scope of stringing work general Supporting documents [ drawings / Earthing measurement / Final Report of TowerErection / other approval Line route [ Bush clearing / Other utilities / determination drum place, winch place /access road etc ].  Material to be installed [ OPGW / Conductors / Earth wires / lnsulators /Fittings /Accessories ].  Equipments and Tools [ Tensioner / Puller / Counter weight / Crane /Truck / drumstand / theodolite, etc ].  Safety Tools [ Equipments and Workers ].2.

The relative documents are as follows:  Final Check of Tower Erection of all towers of the stringing section.  Earthing Measurement records for the respective towers.  Bush Clearing in the respective stringing section.

The tools prepared including all tools for safety of the workers Safety Meeting Always before starting to work, the supervisor and his foreman must perform Safety ToolBox Meeting with their own crews. Safety Tools boxmeeting should consists of followingtasks :  The Task and target of the respective date work.  Checking safety tools for workers and the equipments.  Checking healthy and conditions of workers and equipments.List for safety tool  Safety Belts  Measurements  Working scheduleNote : The task of the foreman of each crews to check and direct responsible for safety ofthe workers and the equipments. INSTALLATION OF INSULATORS Insulators, running out blocks and the fittings transported to each towerlocation and liftedcarefully by winch and rope. Be sure that the insulators type installed are according totower TruckNote : Numbers of drums of conductors should be according to the required lengths. 3. INSTALLATION OF RUNNING BLOCK Running block for conductors will be fixed to the yoke plate and lifted together with theinsulator strings to the fixing points. Running block forearth wire lifted until EW cross arm. 4. ANCHORAGE Towers at temporary termination should be supported with steel wire ropes dia. ± 13 mmas an anchor of the towers - The wires attached at the each cross arm PULLING PILOT WIRE PULLING EARTHWIRE & CONDUCTOR ln case the pilot wire has been completely pulled and connected to both sides [winch andtensioner], The other two wheels used for each line conductor. SAGGING After pulling is completed , sagging of earth wire and conductors can be carried outaccording to the sag chart and sagging operation record as attached.Procedure calculation measurement for sagging can be applied into two method of saggingdepending on the line profile of the section.ln general the method sagging rneasure FITTING & CLAMPING When the conductors are properly adjusted according to sag chart, conductors should bemoved one by one from the running block wheels to the respective clamps of the insulators/ earth wire
