6 Installation 1. Check completeness of NS-Parts 2. Prepare your tools 3. Define installation location 4. Prepare the contact and messenger wire 5. Measure the average high of contact wire and the Hogging factor 6. Installation of messenger wire insulator 7. Place Neutral Section Insulator body 8. Cut contact wire 9. Adjustment of NS height, level and suspension 10. Install skids (parallel to track, with Jig) 11. Controll everything page 6

7 Controll complettness of Parts Controll your neutral section parts according to the list of parts page 7

8 Tools for Installation Make sure you got all nessesary tools for the installation 1 Ring spanner 16/17 mm 1 Torque wrench 17 mm (50 Nm) 1 Adjusting JIG FLURY 1 Spirit level (FLURY Art. no ) 1 Metal cutter (+ possibly 1 metal cutting saw) 1 Copper hammer approx. 2 kg 1 Flat nose pliers or universal pliers 1 Straightening wood 1 Measuring scale Additionally for: - Cut-in the messenger wire insulator - Replace of a used neutral section insulator 1 Pulley block with 2 cable sockets (mounting dead end) page 8

9 Preparation of contact and messenger wire Straighten the contact wire at the installation location and make sure it is not twisted! Place the contact wire and the messenger wire in the middle of the track (+/- 50 mm). Contact wire and the messenger wire must be positioned vertically above each other. page 9

10 Location As a standard for phase breakers a pylon should be placed in the middle of the system. PYLON page 10

11 Installation Instruction Installation direction Installation direction Turn to adjust Place the JIG with red side to the installation direction. Adjust the spirit level for the red side. Turn the JIG 180 and place the JIG with yellow side to the installation direction. Adjust the spirit level for the yellow side. page 11

16 Installation with Hogging page 16

17 Negative Presag (Hogging) of the NS Measure the high of the contact wire at the guide arm clamps before (A) and after (B) the installation location. A B page 17

18 Negative Presag (Hogging) of the NS Calculate the average value: A + B 2 A B page 18

19 Negative Presag (Hogging) of the NS Measure the hogging factor X X page 19

20 Determination of Hogging Use a spring balance and pull the contact wire with 120 N N to measure hogging factor (x). page 20
