| Preformed line product
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 . |
