Heat-shrinkable low and medium voltage moulded shapes - Part 3: Specification for individual materials - Sheet 101: Heat-shrinkable, polyolefin moulded shapes for low voltage applications

IEC 62677-3-101:2018 is applicable to heat shrinkable low voltage moulded shapes in a range of configurations suitable for insulation, environmental sealing, mechanical protection, strain relief for power cable terminations, joints and stop ends. These moulded shapes have been found suitable for use for temperatures between -40 °C and 100 °C. The moulded shapes can be supplied with a pre-coated adhesive. A guide to adhesive compatibility and temperature performance is given in Annex A. The manufacturers/suppliers can be consulted for options. The material is available in two types:
- Type A - Flame retardant
- Type B - Not flame retardant
Materials which conform to this document meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and will not be based on this document alone. The tests specified are designed to control the quality of the moulded shapes but it is recognized that they are designed to be used in low and medium voltage cable accessories and, as such, electrical performance will be proven as part of the assembly. Examples of this are described in EN 50393, HD 629 and IEC 60502-1.

Ces profilés sont jugés adaptés pour des utilisations dans la plage de températures de –40 °C à 100 °C. Les profilés peuvent être fournis avec un adhésif prérevêtu. L'Annexe A fournit un guide sur la compatibilité des adhésifs et la performance en température. Les fabricants/fournisseurs peuvent être consultés pour les options.
Deux types de matériaux sont disponibles:
- Type A - Retardateur de flamme
- Type B - Non retardateur de flamme
Les matériaux conformes au présent document satisfont à des niveaux établis de performance. Cependant, le choix d’un matériau par un utilisateur, pour une application spécifique, sera fondé sur les exigences réelles nécessaires pour obtenir une performance adéquate pour l'application concernée, et ne sera pas fondé sur ce seul document. Les essais spécifiés sont conçus pour contrôler la qualité des profilés, mais il est reconnu qu'ils sont conçus pour être utilisés dans des accessoires de câbles basse et moyenne tensions et, à ce titre, la performance électrique sera prouvée dans le cadre de l'assemblage. Des exemples sont développés dans l'EN 50393, le HD 629 et l'IEC 60502-1.

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 ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

Sheet 101: Heat-shrinkable, polyolefin moulded shapes
for low voltage applications
1 Scope

This part of IEC 62677 is applicable to heat shrinkable low voltage moulded shapes in a range

of configurations suitable for insulation, environmental sealing, mechanical protection, strain

relief for power cable terminations, joints and stop ends. These moulded shapes have been

found suitable for use for temperatures between –40 °C and 100 °C.

The moulded shapes can be supplied with a pre-coated adhesive. A guide to adhesive

compatibility and temperature performance is given in Annex A. The manufacturers/suppliers

can be consulted for options.
The material is available in two types:
Type A – Flame retardant
Type B – Not flame retardant

Materials which conform to this document meet established levels of performance. However,

the selection of a material by a user for a specific application will be based on the actual

requirements necessary for adequate performance in that application and will not be based on

this document alone.

The tests specified are designed to control the quality of the moulded shapes but it is

recognized that they are designed to be used in low and medium voltage cable accessories

and, as such, electrical performance will be proven as part of the assembly. Examples of this

are described in EN 50393, HD 629 and IEC 60502-1.
