WG A4D Definition of Tree Retardant Crosslinked Polyethylene

• Return to Subcommittee A - Cable Construction and Design

Officers:

• Chairman - Serge Pelissou, Hydro Quebec
• Vice Chairman - Richie Harp, TXU

Scope:

The A4D Discussion Group is examining issues related to the performance of cables insulated with what is generally called tree retardant crosslinked polyethylene (TRXLPE). The term TRXLPE is often used in the electric utility industry but currently there is no uniformly accepted definition. This group is working to consolidate and document the activities that have been conducted since 1997 to define TRXLPE based on performance data.

Minutes

• WG A4D completed publishing all the work that the Discussion Group did over a period of 12 years in an attempt to define Tree-Retardant Crosslinked Polyethylene.  The Discussion Group started in 1996 and disbanded in December 2008 after the publication of this work.
  
  A shorter version of the work was published in the September/October 2008 Issue of the Electrical Insulation Magazine.  However, due to the nature of the data that was shared within the Discussion Group, it could not all be published in public forum such as the Electrical Insulation Magazine.  A more complete version of the work, with tables of data and charts is published in the two documents that follow here the Download section of the ICC Website.  The first document is a summary of the work that was done and the second document shows examples of the calculation method that was used.
  • A Review of Possible Methods for Defining Tree Retardant Crosslinked Polyethylene (TRXLPE) available as an MS-Word File
  • UPCSTAC Randomized AWTT Data Analysis (example calculations) available as a PDF File
