Standard Specification for Crosslinked Polyethylene Insulation for Wire and Cable Rated 2001 to 35 000 V
STANDARD published on 1.10.2020
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers a crosslinked polyethylene insulation for electrical wires and cables for conductor sizes 8 AWG (8.37 mm2) and larger. The base polymer of this insulation consists substantially of polyethylene. The partial discharge, ac voltage, insulation resistance, and dc voltage shall be tested to meet the requirements prescribed. The accelerated water absorption, permittivity and dissipation factor, U-bend discharge, and surface resistivity shall be tested to meet the requirements prescribed. The heat distortion, and percent hot creep and percent hot set shall be tested to meet the requirements prescribed.
