Armor Rod Aluminum Alloy Helical

The preformed armor rod is used to protect the wire from vibration, clamping stress, friction, arc and all other external damage. The pre-twisted short protective wire can protect the wire from arc, friction or other damage on the short-span line when the wire vibration is not serious. They can also be used as repair strips to repair damaged wires and restore their original mechanical strength and conductivity.

Product Details

The protective rod is divided into FYB and FYH types. It is a pre-twisted wire used to increase the rigidity of the conductor and repair the broken strand of the conductor in the suspension clamp of the overhead power line. It can also be used to protect the branch lines and avoid damages caused by arcs and friction at the branch points of the wires.

 

Features 

1) Less wear: Since the guard wire and the short guard wire hold the wire tightly, the wire slippage is avoided, so the wire abrasion can be reduced to a minimum;

2) Anti-loosening: Because the preformed armor rod wire has tight grip elasticity, it can guarantee *not loose;

3) Good corrosion resistance: the lines are treated with rust prevention to ensure strong corrosion resistance;

4) Simple installation: without any tools, it can be quickly and easily installed on site with bare hands, which can be completed by one person;

5) The installation quality is easy to guarantee: no special training is required, the naked eye can be inspected, and the appearance is simple and beautiful;

6) Strong general performance: It can be used with a variety of fittings.

 

The main dimensions of the pre-twisted wire conform to the following figure and Table 1-2.

The meanings of letters and numbers in the models in the table are: -Protection; Y--pre-twisted wire; H--protection line; B--repair strip; number--applicable wire cross section; numerator represents aluminum cross section; denominator represents steel cross section.

 

Continuation instructions 

1) When the outer aluminum wire of the copper core aluminum stranded wire and the outer aluminum wire of the aluminum wire have less than 25% of the lines broken, the preformed armor rod short protective wire MG can be used to repair it, which can restore the best mechanical and electrical performance;

2) When 25%-50% of the outer aluminum wire of the copper core aluminum stranded wire and the outer aluminum wire of the aluminum wire are broken, the preformed armor rod protective wire AR can be used to repair it, which can restore the best mechanical and electrical performance .
