Double Support Tie

Double Side Ties, manufactured of aluminum covered steel, secure conductors on double arm construction in the side groove of interchangeable headstyle insulators and are intended for larger line angles than top groove style ties. Double Side Ties feature an elastomeric tube that surrounds the bare conductor with a resilient cushion, providing superior abrasion protection under all types of conductor motion, including low-frequency galloping and high-frequency aeolian vibration. As a result, Double Side Ties with tie tubes provide better protection than hand ties over protective rods by providing an armoring layer that eliminates abrasion damage of the conductor and insulator caused by conductor motion. This extends the life of the electrical system and reduces maintenance.

Applicable to interchangeable headstyle insulators - C, F, and J-Neck
Accommodates conductors from 0.245" - 1.240" diameter
Pre-contoured Tie ensures a tight fit
Mitigates long-term issues caused by Radio Influence Voltage (RIV)
Accommodates line angles up to 80-degrees (40-degrees per Insulator)
Exceeds NESC requirements for unbalanced load
Reduces or eliminates abrasion caused by vibration
Ideal for severe weather applications and system hardening activities
Resiliency of the tie protects the conductor
Test reports available upon request
