Top Tie
May 4,2017hits:2026

General recommendations

Top Ties are intended to secure bare or jacketed distribution conductors in the top groove of vertically mounted insulators. They provide an improved method of securing conductors compared to clamp top insulators or handmade binds.

Top Ties with pad are recommended for use with bare conductors. They provide superior abrasion protection for the conductor under all types of motion, including Aeolian vibration, galloping and sway.

The pad component is recommended because it surrounds the conductor with a resilient cushion which eliminates abrasion at the conductor-insulator interface.

Pads are not required with jacketed conductors

 

Interchangeable head-style insulator:

To insure proper fit and service life, it is recommended that only insulators corresponding to C-neck, F-neck, J-neck or K-neck be used. These neck-diameter and groove-height dimensions appear on ANSI standards.

Consult the factory for engineering recommendations on non-interchangeable headstyle insulators. A sample of the insulator in question is desirable.

 

Conductor size:

Top Ties can accommodate conductor diameters form 0.190” to 1.585” for F neck insulators and 0.190” t0 1.240” for other size insulators as long as the insulator top groove is large enough. Consult the table in this section for minimum groove radii required for specific tie and conductor diameter range.

 

Line angles

On vertically mounted insulators, Top Ties are recommended for line angles up to 10 degrees. Larger angle can be obtained under certain conditions.

 

Mechanical Strength

The Top Tie has a slip load exceeding 700 lbs. in unbalance load conditions. The maximum holding strength is usually sufficient to contain a broken conductor to a single span. Top Ties are designed however to relieve the load before severe damage occurs to the pole’s structural components.

The Top Ties is designed to permit controlled movement of unbroken conductor, reducing cantilever loading at the base of the insulator. The resilience of the Tie permits it to then restore itself.

 

Vibration Dampers

Top Ties maximize the vibration fatigue life of the conductor to the extent that its original endurance is not reduce by abrasion, However, on lines subject to long periods of vibration that might approach the fatigue life of the conductor, cause inner wire fretting or scoring of the insulator glaze, the use of spiral Vibration Dampers is recommended.

 

Radio interference

The R.I.V characteristics of Top Ties are equivalent to those of well-made handbinds when originally installed. During service life the pre-contoured Tie assures continued fit which would have better R.I.V than a loosened tie wire.

 

Tapping

Tapping over the applied legs of Top Ties is not recommended. Taps can be made on the conductor beyond the ends of the legs, or the conductor can continue through the crossover point of fitting, with connectors applied to the continued tail.

 

Application and inspection

Ensure the correct size fitting is used. For detailed method of installation both by hand and with hot sticks, refer to application instruction. The design dimensions of the Top Ties and pads are difference from those supplied without Pads for jacketed conductors. Ensure that correct design is used.

 

Material used

Top Ties are made of material compatible with the conductor to which they are applied.

 

Production Characteristics

  • Color Code: Assist in identification of conductor size
  • Tie pad: for bare conductors, each tie is supplied with a neoprene tie pads that is detached and applied over the conductor centered in the top groove of insulator. For jacketed conductors a tie pad is not provided.
  • Identification label: Shows catalogue number and strand diameter range.
  • Lay direction: Must be same as that of the outer layer of the strand to which it is applied
