CEI EN 60684-3-281

This part of IEC 60684 gives the requirements for two types of
heat-shrinkable, polyolefin sleeving, semiconductive, with a
nominal shrink ratio of 3:1.

This sleeving has been found suitable up to temperatures of 100
°C.

– Type A: Thin wall Internal diameter up to 195,0 mm
typicall

 – Type B: Medium wall Internal diameter up to 120,0 mm
typically

These sleevings are normally supplied in the colour black.

Since these types of sleevings cover a significantly large range
of sizes and wall thicknesses, Tables A.1 and A.2 in this standard
provides guidance to the range of sizes available. The actual size
shall be agreed between the user and the supplier.

Materials which conform to this specification meet established
levels of performance. However, the selection of a material by a
user for a specific application should be based on the actual
requirements necessary for adequate performance in that application
and not based on this specification alone.

This sleeving is designed to be used in MV cable accessories and
as such electrical performance must be proven as part of the
assembly. Examples of this are described in HD 629 and IEC 60502
series.
