La CEI 60684-3-281:2010 donne les exigences relatives à deux types de gaines thermorétractables, en polyoléfine, semiconductrices, de rapport de rétreint nominal 3:1. Ces gaines se sont révélées être adaptées à des températures jusqu'à 100 °C.  - Type A: Paroi mince - Diamètre intérieur type jusqu'à 195,0 mm  - Type B: Paroi moyenne - Diamètre intérieur type jusqu'à 120,0 mm

Gibke izolacijske cevi - 3. del: Specifikacije za posamezne tipe cevi - 281. list: Toplotno skrčljive poliolefinske cevi, polprevodne (IEC 60684-3-281:2010)

Ta del IEC 60684 podaja zahteve za dva tipa toplotno skrčljivih poliolefinskih cevi, polprevodnih, z nazivnim razmerjem krčenja 3:1. Za te cevi je ugotovljeno, da so primerne za temperature do 100 °C.
- Tip A: Tanka stena. Notranji premer običajno do 195,0 mm.
- Tip B: Srednje debela stena. Notranji premer običajno do 120,0 mm.
Te cevi se običajno dobavljajo v črni barvi. Ker te vrste cevi zajemajo precej velik razpon velikosti in debelin stene, podajata preglednici A.1. in A.2 v tem standardu vodilo o razponu razpoložljivih velikosti. Dejanska velikost se dogovori med uporabnikom in dobaviteljem. Materiali, skladni s to specifikacijo, ustrezajo vzpostavljenim ravnem delovanja. Vendar mora uporabnik material za določeno uporabo izbrati na podlagi dejanskih zahtev za ustrezno delovanje pri takšni uporabi in ne le na podlagi same specifikacije. Ta cevi so zasnovane za uporabo v kabelskih dodatkih srednje napetosti, zato mora biti dokazana njihova električna zmogljivost, kadar so del sklopa. Primeri tega so opisani v HD 629 in seriji IEC 60502.

Overview

EN 60684-3-281:2010 (CLC adoption of IEC 60684-3-281) specifies requirements for heat-shrinkable, polyolefin sleeving, semiconductive - a type of flexible insulating sleeving used primarily in medium-voltage (MV) cable accessories. The standard covers two nominal types with a 3:1 shrink ratio and reports suitability for continuous use up to 100 °C:

• Type A - Thin wall: internal diameters typically up to 195 mm
• Type B - Medium wall: internal diameters typically up to 120 mm
  These sleeving products are normally supplied in black and are intended to meet established electrical and mechanical performance levels when used in cable accessory assemblies.

Key topics and requirements

EN 60684-3-281 is a product specification sheet that builds on the general definitions and test methods of the IEC 60684 series. Important technical points include:

• Material & form: Heat-shrinkable polyolefin, semiconductive surface properties (to control electrical stress in accessories).
• Shrink performance: Nominal 3:1 shrink ratio - expanded and recovered diameters are part of the designation and must be agreed with the supplier.
• Thermal limits: Designed for service temperatures up to 100 °C; includes heat ageing tests (e.g., exposure at 135 °C for specified durations).
• Mechanical properties: Requirements for tensile strength and elongation at break (representative minimums are specified in the standard), heat shock, low-temperature bending (no visible cracking), dimensional stability and secant modulus limits.
• Electrical properties: Volume resistivity limits to define the semiconductive characteristic (used to manage field grading in MV accessories).
• Chemical resistance: Specified resistance to selected fluids including mineral insulating oil, isopropyl alcohol and de-ionized water (tests at defined temperatures such as 85 °C for water).
• Conformance testing: Typical sizes for type verification are defined; sleeving should be shrunk prior to testing according to the standard’s conditioning procedure.

Applications - who uses this standard

EN 60684-3-281 is primarily used by:

• Manufacturers of MV cable accessories (terminations, joints, stress control layers) who specify semiconductive heat-shrink sleeving for field grading and insulation support.
• Specifiers and purchasers in utilities, OEMs and EPC contractors selecting sleeving for power cable systems.
• Test labs and certification bodies performing material and component verification against IEC/CENELEC requirements. Practical applications include stress control boots, conductive grading layers, and protection/insulation interfaces in cable assemblies where controlled surface conductivity is required.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to
