Helical Preformed Armor Rod

Helical preformed armour rods
 
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. 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
 
1.Helical armor rod is used to protect conductor from vibration, clamp pressure, friction, arc and all the other adventitious damnification. The short Helical armor rod could protect the conductor.
from arc, friction and other damnification at a relative short span circuitry under the condition that the conductor vibration is not serious.
 
2. Helical armor rod and short Helical armor rod have simple structures.
 
3.A set of rods make a hollow tube, it can protect the conductor by the grip which is produced   when rods packs the conductor.
 
Features:
 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.
