Double Support Tie

Double Support Ties are recommended as an improvement over Armor Rods secured with hand tie wire. For areas subject to both wind sway and vibration. Double Support Ties provide superior abrasion protection, to a well made hand tie - Armor Rod combination in regard to conductor fatigue.

Product Description

MATERIALS
Ties - (2 each) Aluminum alloy.
Pads - (2 each) Specially formulated elastomer
Identification tags - (2 each) Identifies catalog number, neck size, nominal conductor size and conductor diameter range.
Color code - Each Double Support Tie has two color codes. The inside code identifies the proper conductor size and the leg color code identifies the insulator neck size:
Insulator identification mark (identifies insulator head size)
Black - C Neck
Yellow - F Neck
Green - J Neck
General Recommendations
To insure proper fit and service life, it is recommended that only insulators corresponding to C Neck, F Neck, or J Neck be used. These neck diameter and groove height dimensions appear in ANSI Standard for low and medium voltage pin type insulators.
Double Support Ties are recommended as an improvement over Armor Rods secured with hand tie wire. For areas subject to both wind sway and vibration. Double Support Ties provide superior abrasion protection, to a well made hand tie - Armor Rod combination in regard to conductor fatigue.
Pad
The pad component is provided for bare conductor because it prevents contact with the insulator and compensates for insulator misalignment. With the pad. Double Support Ties not only replace armoring products but provide superior protection by eliminating rather than sacrificing outside surfaces to abrasion.
Maximum Size
Double Support Ties are available for conductors up to 1.240" O.D. depending on the insulators top groove radius.
Line Angle
On vertically mounted insulators. Double Support Ties are recommended for running line angles of up to 10 degrees.
Unbalanced Loading
Under unbalanced load conditions, the Double Support Tie has the resiliency to permit some longitudinal displacement of the conductor over the insulator without loosening the tie or damaging the conductor.
Radio Interference
The RIV characteristics of Double Support 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
Tapping over applied legs of the Double Support Tie is not recommended. Taps should be located at least 6 inches from the end of the legs.
