Tie - Aluminum alloy for aluminum based conductor.
Center section - Specially formulated elastomer.
Identification tag - Identifies catalog number, neck size, nominal conductor size and conductor range.
Color code - Identifies proper conductor range.
Insulator identification mark (identifies insulator head size)
Black -C Neck
Yellow -F Neck
Green -J Neck
To insure proper fit and service life, it is recommended that only insulators corresponding to C Neck, F Neck, or J Neck be used as specified by ANSI C29.5 The top groove radius, neck size, and groove height relationship corresponding to each neck size are shown
at the beginning of each listing. Longspan Ties are recommended as an improvement over Armor Rods secured with hand tie wire. For areas subject to both wind sway and vibration, Longspan Ties provide superior abrasion protection and are superior to a well made hand tie - Armor Rod combination in regard to conductor fatigue.
Longspan Tie Pad
The pad component is recommended for bare conductor because it prevents contact with the insulator and compensates for insulator misalignment. With the pad, Longspan Ties not only replace armoring products, but provide superior protection by eliminating abrasion rather than sacrificing outside surfaces to abrasion.
Longspan Ties are available for conductors up to 1. 240" O. D. depending on the insulators top groove radius.
On vertically mounted insulators, Longspan Ties are recommended for running line angles of up to 10 degrees. Larger angles can be turned when Longspan Ties are used with Side Ties or with pins and brackets having various degrees of cant.
Under unbalanced load conditions, the Longspan Tie has the resiliency to permit some longitudinal displacement of the conductor over the insulator without loosening the tie or damaging the conductor.
The RIV characteristics of Longspan Ties are superior to those of well made hand ties when originally installed. During service-life, the pre-contoured helix assures consistent fit which has better RIV characteristics than loosened tie-wire.
Tapping over applied legs of the Longspan Tie is not recommended. Taps should be located at least 6 inches from the end of the legs.
At double crossarms, double Support Ties can be used to cross major highways and railroads, or turn angles where it is practical to hold the conductor in the top groove during installation.
