Metal Top Tie Model: SDB High quality, low price, excellent service
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
Material: Top Ties are made of material compatible with the conductor to which they are applied
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.
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.
Insulators: Φ57mm (C Neck), Φ73mm (F neck) and Φ89mm (J neck)
