Method Statement for Installation of 30kV Conductor (Crossing with existing 20kV PLNs Overhead Line)

1. Work Procedure and Job Safety Analysis. 1.1 Preparation

1) Man Power.

Safety Induction for workers by Safety Officer. Tool Box meeting before start of work.

2) Necessary tools.

All necessary electrical tools shall be passed inspection.

3) Work Permit.

Permit shall be obtained from PLN & local government.

4) Installation of scaffolding.

Install of scaffolding for work access and inspection before use.

1.2 Personal Protective Equipment

Appropriate equipment, e.g. helmet, safety shoes, goggle, masker, safety

harness and other equipment, shall be given to related persons before

commencing work.

1.3 Others.

1) Barricade, sign board and temporary protection.

To be kept in container or job side and to be placed as required, refer to

each activity.

2) First aid box must be available on job site.

2. Method Statement 2.1 General Condition

Height of existing 20kV tower or pole is 13 meters, for new 30kV pole is 10

meters. Therefore, installation of 30kV overhead line will be under 20kV

existing PLNs transmission line.

2.2 Preparation Work.

1) Ensure all the necessary electrical and hand tools complete already.

2) Ensure that storage of materials not obstruct to road traffic and public

facilities.

3) Puller preparation

- Placement of engine puller in place has been determined previously

- Dig a hole for anchor engine

4) Preparation tensioner

- Placement of a tensioner in place has been determined previously

- Transporting and Placing Conductor on location tensioner

- Preparing Conductor on Drum Stand (drum jack)

5) Installation of roller

- Installation of roller for conductors at pole to be done

6) Hold the rope

- Connecting the rope puller and tensioned with polypropylene 12 mm

7) Stringing Wire Rope 12 mm

- Stringing wire rope 12 mm with polypropylene 12 mm which had

been held earlier.

2.3 Procedure.

1) Before start the work, existing 20kV line must be shut down for a while.

2) Install scaffolding at the existing 20kV pole span, which crossing with

new 30kV line.

3) After the existing 20kV transmission line shut down, ensure that no

electrical power at existing conductor cable using grounding device or

Jin Pole.

4) Install the permanent safety nets under the 20kV transmission line

which crossing with new 30kV line and install warning sign under 20kV

line for safety guidance.

5) After point 3 and 4 finish, 20kV line can be operated.

6) During stringing work, the contractor shall take all necessary steps to

insure proper temporary grounding of the cables and equipment.

7) Ensure new pole at crossings with existing 20kV line shall be finish

before stringing work.

8) Install scaffolding at new pole.

9) First Conductor phase Stringing

- Held the rope polypropylene 12 mm

- Pulling the wire rope 12 mm with polypropylene 12 mm which had

been held earlier

- Pull the conductor and polypropylene 12 mm with wire rope 12 mm

STRINGING OF 30KV OVERHEAD LINE

4

- Pulling the wire rope 12 mm with polypropylene 12 mm

- Repeat the procedure until it is fixed three conductors

10) Second Conductor phase Stringing

- Repeat the first phase Stringing

11) Third Conductor phase Stringing

- Repeat the second phase Stringing

12) Place the tension insulator sets

- Place the tension insulator sets in tower

- Conductor pieces one by one and "press" in the tension clamp

conductor to be connected to the insulator sets.

- Repeat the procedure to all the conductors

2.4 Others

1) Cleaning area after work finished.

2) At the work area of cabling works shall be provide of security and safety

person for control activity.
