Overview
Easy Installation and Reliable Sectionalizing of Overhead Power Networks for Reduced Outage Time

Our AMPACT In-Line Disconnect Switches (ILD-II) are designed to provide reliable sectionalizing of overhead power lines for maintenance or emergency isolation, resulting in reduced outage time. They combine the reliability of copper blade components, a double string of polymeric insulators, and the AMPACT dead-end yoke assembly. The result is an in-line disconnect that can be installed without tensioning devices. The performance of AMPACT dead-end technology has been used in the design of the AMPACT ILD-II switches. The dead-end yokes are bolted to two polymeric insulators.

The copper blade assemblies are connected to the AMPACT dead-end yoke assemblies between and below the double string of insulators. These provide adequate space for cutting the conductor after installation of the TE AMPACT fired-on dead-end connectors. Standard AMPACT tap application procedures are used to make electrical and mechanical connections simultaneously.

Our ILD-II switches can be installed on standard stranded all-aluminum conductors (AAC) or aluminum conductor steel reinforced (ACSR) in conductor sizes from #2 to 954 AAC.

Key Features

  • Simultaneous mechanical and electrical connection using the AMPACT tap
  • No line-tensioning devices required for installation
  • Double string of polymeric insulators prevents switch rolling
  • Copper disconnect blade assembly suspended below the insulators, simplifying conductor cutting
  1. AMPACT In-Line Disconnect Switches Installation

AMPACT ILD-II In-Line Disconnect Switches provide reliable sectionalizing of overhead power lines for maintenance or emergency isolation, reducing outage time. Built with copper blade assemblies, polymeric insulators, and AMPACT dead-end technology, they install without tensioning devices and support simultaneous mechanical and electrical connections on standard AAC or ACSR conductors.

AMPACT ILD
FAQ

Frequently Asked Questions

Question: What are TE AMPACT ILD switches made from? 

Answer: TE ILD switches are made from casted aluminum, with polymeric insulators and a copper blade. The Deadend Tap C-body and wedge are made from aluminum alloys. The hardware is made from 304 Stainless Steel. 

 

Question: What conductor sizes can the AMPACT ILD be used on? 

Answer: AMPACT ILD connectors can accommodate main conductors from #2 AAC to 954 AAC (7.41 mm - 28.58 mm). 

 

Question: Does AMPACT ILD require any special installation tools? 

Answer: The switch can be installed using our AMPACT tool.

  

Question: What voltage class does it work on? 

Answer: There are 5 voltage classes the switches can be purchased in, rated up to 69kV. The voltage classes include 15, 29, 35, 46, and 69 kV. 

 

Question: What amperage level does it support? 

Answer: The switch is available in 2 versions: 900A and 1200A of continuous current. 
 

Question: What industry standards does the AMPACT ILD switch meet? 

Answer: ANSI: C37.32, IEEE: C37.20, C37.34, CSA: C83 RUS Listed 

 

Question: Can AMPACT Deadend Taps be reused? 

Answer: TE recommends using a new, unused connector for each installation.  
 

Question: Can AMPACT ILD be installed using industry-standard hot sticks? 

Answer: Yes, AMPACT ILD connectors can be installed using industry-standard hot sticks in conjunction with our AMPACT hot stick adapter.
