Low Voltage Heat Shrink, Medium Voltage Heat Shrink & High Voltage Heat Shrink

     Q:  How does Raychem (Tyco Electronics) define low, medium and high voltage levels?

     A:  As follows:

Low Voltage Heat Shrink is generally rated in the 1000 to 2000 volts range

Medium Voltage Heat Shrink is generally rated in the 5kV to 35kV range

High Voltage Heat Shrink is generally rated up to 230kV!  Yikes.

Within each category there are a number of products.  Please always check with us to be certain you know the exact voltage rating of any Raychem product you purchase.
