Preformed Line Products SSDE-9131 SLACK SPAN DEAD-END .666-.783 NEW
Dead-end Material Helical Leg Section:
-Aluminum covered steel. An aluminum alloy version is available for corrosive environment.
Crossover Marks:
-Indicates starting point for application on conductor.
Color Code & Length:
-Assists in identification of conductor diameter range, corresponding to tabular information listed on catalog pages.
Covered Loop Section:
-Elastomeric compound specifically formulated for resistance to ozone attack, weathering and abrasion.
Product Identification Tag/Warning Label:
-Identifies catalog number, appropriate conductor types and sizes and product usage limitations.
Slack Span Dead-end is intended for use on aluminum based conductors with diameter ranges from .229" to 1.216". It is specifically designed to terminate primary, secondary and neutral conductors. Each Slack Span Dead-end covers a range of conductor diameters as outlined on catalog pages.
Conductor Tension Limitations:
-The Slack Span Dead-end is specifically designed for LIMITED TENSION APPLICATIONS. IT SHOULD NOT BE USED AS A FULL TENSION DEAD-END. The Slack Span Dead-end is intended for use where guying (or other) restrictions prevent full tension spans. While individual utility construction and safety practices should dictate actual installations, each Slack Span Dead-end has a warning label attached suggesting a maximum allowable loaded tension of 1000 lbs. This value does not indicate a holding strength rating for Slack Span Dead-ends; rather, it suggests a practical limit for tensions in this type of construction. The Slack Span Dead-end replaces conventional Dead-ending equipment used in slack span construction. Dead-end insulators, clamps, and associated hardware when used in this way normally do not offer tight, solid electrical connections between each other. This "looseness" can allow intermittent contact and ultimately produce troublesome RFI (RIV) and TVI. Construction practices utilizing the Slack Span Dead-end can minimize this problem. The Slack Span Dead-end is specifically designed to be installed on pin, line post or spool insulators when used in limited tension construction. Refer to Figure 1 for a typical installation.
Covered Loop Section:
-The loop of the Dead-end is covered with an elastomer to provide protection against abrasion and damage to the glaze of the insulator. It also helps minimize RFI, TVI, etc. The Slack Span Dead-end is designed to grip the conductor uniformly to prevent distortion. It also offers a unique design that eliminates bolts, nuts, washers and other component parts that may become lost or damaged during installation or in service.
-Where requirements call for increased tension applications, use either the Distribution Grip Dead-end or the Overhead Deadend. On jacketed conductors, use either Coated Dead-ends or Distribution Grip Dead-ends.
-Where requirements call for Dead-ending conductors associated with bare neutral messengers or self-supporting cable used in making service drops, use Service Grip Dead-ends.
*****Distribution Grip (Slack Span/Overhead) Dead Ends are not recommended for use with high temperature/low sag conductors such as ACSS, ACSS/AW, ACSS/TW, ACCR or other types of conductors with loose, and/or annealed outer layer strands. Typically THERMOLIGN® Dead Ends are suggested for these applications; consult Preformed Line Products for further information.****
