Super Top-Tie® Line Ties

For Pin, Post and Spool Insulators

ALUMINUM COATED STEEL
STT

Made of aluminum-clad steel compatible with aluminum, aluminum-alloy and ACSR conductors in the top grooves of vertical-mounted *ANSI Class C, F, J and many non-standard pin and post insulators (single- or double-support) or on *ANSI 53-2 spool insulators (horizontal or vertical).

High-density polyethylene hooks provide the wide application range and ensure proper installation. If used over armor rods (not required), select tie size based on total conductor/armor diameter. Semiconductive-rubber pad and high-densitypolyethylene on loops protect against abrasion of insulator, conductor and tie. Fit is resilient and provides superior performance under galloping and aeolian vibration. Install by hand or with hot-line tools.

*Super Top-Tie STT10 - STT130 also fit many foreign or reclaimed pin and post insulators with neck sizes 2-1/4" - 3-1/2".
Consult Hubbell Power Systems, Inc. for use on pins and posts outside these dimensions.
