Whether the 500kv overhead conductor outer bolts should be cold welded

1. Has a certain tension overhead wire alignment, the wire and lose fastening, spread the injury prevention wire and steel wire.

2. Pre-twist ring spacing should be consistent with the lead pitch adjustment. Die with the distance pre-twist ring should be appropriate.

3. Aluminum wire steel tension should adjust the basic uniform, to avoid the wire coil bending.

4. Aluminum monofilament in collision injury is strictly prohibited during the transfer process line.

5. Check the tightness of the die, and the timely replacement of the die, to avoid the single fault phenomenon.

6. Platoon line should avoid the abrasion between line and line. Should pad between layer and layer of paper if necessary.

7. Should check before driving the twister and take-up, ensure the twister nobody, defend the net in place, the line in traction drive wires in place to start the program, such as speed drive only after the alarm bells ringing. No alarm it is forbidden to drive.

8. Strengthen the inner, and outer twister guardianship, and keep a single line break after long meters into the twister. Once the break line should stop welding repair in time.

9. With particular emphasis on because the agreement calls for outer no solder joints, the outer wire break when must use cold welding, id card, and receipt should indicate the solder joint meters long, in order to negotiate with the customer communication. Inner available butt welding, but must be annealed. The inner bolt into the tube must be welding processing good reproduction, it is strictly prohibited to conceal not continue production welding, and serious consequences will bear legal responsibility.

In addition, drawing for the smooth surface of the wire, wire, and cable surface with a layer of soft things and also ground timeliness, the single line also needs to pay attention to not have the phenomenon of friction.
