Preformed armour rods for ADSS/OPGW cable

Specifications

Preformed armor rods

Armor rods Application&Structure

1.Preformed armour rods protect wire from the vibration of wire, clamp pressure stress, friction, electric

arc and all other external damage. Short preformed armour rods vibration

is not in serious cases, may in a short span of the line to protect against electric arc wire, friction, or other

damage. Can also be used as a conversion, a conversion has been damage to the wire, to restore the

original mechanical strength and wire resistance. Can also be used to protect the branch lines to avoid

cable branch point arc and friction due to the damage.

 2.Preformed armour rods and short preformed

armour rods have simple lines, each formed ATC preformed wire, wire wrapped grip force generated

when, to protect the wire.

 Consideration

1.When the outermost layer of aluminum and aluminum ACSR

conductor in the outermost layer of aluminum has less than 25% of the fracture lines occur, we can use

a short preformed armour rods repair, restore 100% of the mechanical and electrical Performance.

2.When the outermost layer of ACSR and aluminum wire aluminum wire in the outermost 25% -50% of

the fracture lines occur, we can use preformed armour rods repair, restore 100% of the mechanical and

electrical performance .

1)structure is simple, can be easily installed

2)its legs twisted wire preformed and the formation of air traffic control, rear twist for the preforming ring.The formation of preformed wire legs wrapped in wire can produce a very strong grip force, twist the ring to fix the insulator.
3) The clamp distributing the stress uniformity, improved ability of aseismatic without any damage on conductor.
