Slack Span Dead-end
The slack span dead-end is designed on the transmission lines. Its role on the transmission line is to terminate the primary conductors, secondary conductors, and even neutral conductors. This is done so as to prevent the formation of a standing wave on the transmission line that could cause signal reflection and power loss.
Slack span dead-end is made of galvanized steel, it is used on high voltage overhead transmission lines. Slack span dead is designed according to the ANSI C37.4-1996 standard.
The slack span dead-end has a physical design that makes it easy to install and replace. Slack span dead-end is also said to be durable in the sense that it is not easily affected by corrosion or weather elements.
Features
- Made of non-corrosive material
- Suitable for hot stick applications
- The design meets the ANSI standards
- Offers limited tension

Frequently Asked Questions (FAQs)
What is slack span dead-end?
Slack span dead-end is used to terminate primary conductors, secondary conductors, or even neutral conductors that are on a transmission line. Slack span dead-end prevents the formation of standing waves on a transmission line.
What are the components of slack span dead-end?
Slack span dead-end is made up of three parts; the primary conductor, the stiffener, and the terminal. Slack span die is used for both vertical and overhead transmission lines. Slack spans are also called terminators because they can be either horizontal or vertical.
What are the materials for the slack span dead-end?
Slack spans are made from galvanized steel or aluminum. Slack spans are also required to be resistant to aging and weather elements. Slack span dead-end is made of non-corrosive materials for easier maintenance.
What type of slack span dead-end should you use on a particular transmission line?
Slack spans are designed according to the ANSI C37.4 standards or IEEE C62.41 standard. Slack span end is rated depending on the presence of insulators and towers.
How to install Slack span dead end?
Slack span dead ends are used on overhead transmission lines. Slack span can be hot or cold installed depending on the design and location of that section of a particular power line. Slack spans must be installed using care and caution to ensure their integrity. Slack span may also require field adjustments if need be.
