Part 4. The Wind Turbine Installation Steps 

Note: It is prohibited to assemble and install wind turbines on rainy days.

1. The insulated current transmission wires: transmission lines are built in the iron pipe tower. The upper end is led out through the center bore of the wind turbine flange, while the bottom end is led out from the pipe opening which is 30cm away from the ground. The section from the opening to the point which is 60cm beneath ground should be protected by iron pipes whose O.D should be 17mm to 21mm. The underground paths of the transmission lines to the controller can made arrayed and covered with iron pipe or a plastic pipe.

2. The installation sequence of the wind turbines can follow the steps as illustrated in figure3.

2- 1. Place the steel bracket on the ground; block up the flange joint to 1.3m.

2-2. Align the wind turbine flange to the tower flange. Cut away the insulating layer of current transmission wire end ( which is to be connected with the controller) for 10mm, then short circuit the exposed copper wires( screwed together).

2-3. After the flange bolt (9) is mounted with the flat washer ( 10), plug it in the correspondent holes of the wind turbine flange with the bolt’s head up, then through tower flange holes. Set the bolt into the flat washer, the spring washer, and then use a spanner to tighten the nut with the flange bolts. Similarly, plug other bolts, flat washer, and spring washer.

Screw tight all nuts, please refer to Table 2, about the potency dimension needed to tighten them.

3. Align the 2 holes in the blade(6) with 2 holes in the groove of the hub (5), align accurately, then put stainless steel bolt(13) from blade to groove through the holes, then screw lock nut(14)( Attention: lock nut is one-time use, screw tight, do not screw loose, otherwise it will be out of use), installation of other blades follow the same operation, please refer to Table 2 on force dimension of installation.

4. First put the bigger end of the lock nut into a hexagonal hole centered in the hub, then onto the threaded shaft of the generator, press the nut with the left hand while rotating the wheel clockwise with the right. Push the nut, then use the lengthening hex wrench to assist with the right-handed rotation of the wheel. Finally lock the nut (Attention: nut can only push forward, withdrawal is prohibited.) Please refer to Table 2 on Force Dimension of the installation.

5. Clasp fairing (8) with wheel hub (5), align the three notches with blades, and clasp the cone of fairing to get notches to the seam of the wheel hub.

6. The lifting of the wind turbines and tower should be proceeded with the presence of skilled slingers and the security should be guaranteed. The tower’s stance should be executed on the basis of the relevant requirement of permanent construction.

7. After the installation of the tower and lightning protection is finished, use 500V meggar to measure insulating resistance between transmission lines and earth (earth wire can act as ground) in the case of not losing the short-circuited leads of transmission lines, measurement should not be less than 5MΏ, otherwise, the insulating layer may be crushed, damaged or moistened. It should be dealt with immediately.
