Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheet 285: Heat-shrinkable polyolefin sleeving, for medium voltage joint insulation

IEC 60684-3-285:2014 gives the requirements for heat-shrinkable sleeving for medium voltage joint insulation, with a range of shrink ratios. This sleeving has been found suitable up to temperatures of 100 °C. These sleevings are normally supplied in colour, red or brown. Since this type of sleevings covers a significantly large range of sizes and wall thicknesses, the actual size will be agreed between the purchaser and supplier. Materials which conform to this standard 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 standard alone. This sleeving is designed to be used in medium voltage cable accessories and as such electrical performance will be proven as part of the assembly. Examples of this are described in HD 629 and IEC 60502. Keywords: heat-shrinkable sleeving for medium voltage joint insulation, flexible insulating sleeving for electrical purposes

L'IEC 60684-3-285:2014 donne les exigences relatives aux gaines thermorétractables pour isolation de jonction moyenne tension, avec une plage de rapports de rétreint. Il a été établi que ces gaines sont adaptées à une utilisation à des températures allant jusqu'à 100 °C. Ces gaines sont normalement fournies en couleur, rouge ou marron. Comme ce type de gaines couvre une gamme très large de dimensions et d'épaisseurs de paroi, la dimension réelle fera l'objet d'un accord entre l'acheteur et le fournisseur. Les matériaux conformes à la présente norme satisfont à des niveaux de performance établis. Cependant, il convient que le choix d'un matériau par un utilisateur pour une application spécifique soit fondé sur les exigences réelles nécessaires pour obtenir les performances satisfaisantes pour cette application, et qu'il ne soit pas fondé uniquement sur la présente norme. Ces gaines sont conçues pour être utilisées dans des accessoires de câbles moyenne tension et, en conséquence, les performances électriques sont définies dans le cadre de l'assemblage concerné. De tels exemples sont décrits dans le HD 629 et l'IEC 60502. Mots clés: gaines thermorétractables pour isolation de jonction moyenne tension, gaines isolantes souples à usages électriques.

Gibke izolacijske cevi - 3. del: Specifikacije za posamezne vrste cevi - 285. list: Toplotno skrčljive poliolefinske cevi za izolacijo srednjenapetostnih spojev (IEC 60684-3-285:2014)

Ta del standarda IEC 60684 določa zahteve za toplotno skrčljive cevi za izolacijo srednjenapetostnih spojev z določenimi razponi razmerij krčenja. Te cevi so primerne za temperature do 100 °C. Te cevi se običajno dobavijo v rdeči ali rjavi barvi. Ker je ta vrsta cevi na voljo v številnih različnih velikostih ter z različnimi debelinami stene, se o dejanski velikosti dogovorita kupec in dobavitelj. Materiali, ki so skladni s tem standardom, ustrezajo določenim ravnem delovanja. Vendar mora uporabnik material za določeno uporabo izbrati glede na dejanske zahteve, ki omogočajo ustrezno delovanje pri tej uporabi, in ne samo na podlagi tega standarda. Ta cev je zasnovana za uporabo s srednjenapetostnimi kabli, zato se kot del sestava preverja tudi električna zmogljivost. Primeri so opisani v standardih HD 629 in IEC 60502.

Overview

EN 60684-3-285:2014 (equivalent to IEC 60684-3-285:2014) specifies requirements for heat-shrinkable polyolefin sleeving for medium voltage joint insulation. It is one sheet of the IEC 60684 series on flexible insulating sleeving for electrical purposes. The standard covers material, dimensional and performance requirements, test conditions and conformance criteria for sleeving designed for medium‑voltage cable accessories. These sleeving products are typically supplied in red or brown and are suitable for service temperatures up to 100 °C.

Key topics and technical requirements

• Scope and designation: Sleeving is identified using the IEC designation format (example: Sleeving IEC 60684-3-285-75,0/30,0 - RD). Exact sizes and wall thicknesses are agreed between purchaser and supplier due to the wide size range covered.
• Materials and construction: Heat‑shrinkable polyolefin formulations designed for medium‑voltage joint insulation; materials must meet established electrical and mechanical performance levels.
• Preconditioning and test conditions: Typical pre-shrink conditioning (e.g., forced‑air oven cycle) and standardized test atmospheres are specified; testing follows the methods in IEC 60684‑1 and IEC 60684‑2.
• Electrical performance: Requirements include breakdown voltage testing on expanded sleeving (method and rate of voltage application defined), and minimum volume resistivity to ensure insulation reliability.
• Mechanical and thermal properties: Mandated tests cover tensile strength, elongation at break, concentricity, wall thickness, dimensional stability, heat shock, heat ageing and low‑temperature bending - ensuring mechanical integrity in service and after aging.
• Dimensional and concentricity requirements: Expanded and recovered dimensions are controlled; concentricity and wall thickness tolerances are addressed.
• Selection guidance: The standard explicitly advises users to select materials based on application‑specific requirements (installed conditions, accessory assembly testing) rather than relying on the standard alone.

Applications

• Insulation of medium‑voltage cable joints and terminations
• Use within factory or field cable accessory assemblies where heat‑shrink technology provides environmental sealing and dielectric insulation
• Situations requiring a range of shrink ratios and wall thicknesses for different cable constructions

Who uses this standard

• Cable accessory manufacturers and designers
• Utilities and power distribution engineers specifying medium‑voltage splices
• Procurement teams and suppliers of heat‑shrink sleeving
• Test laboratories and conformity assessors validating sleeving performance

Related standards

• IEC 60684‑1 (Definitions & general requirements)
• IEC 60684‑2 (Methods of test)
• IEC 60502 and HD 629 (examples of cable accessory assemblies and performance validation)

EN 60684-3-285 is essential when specifying or validating heat-shrinkable sleeving for medium voltage joint insulation; it ensures consistent performance for flexible insulating sleeving for electrical purposes while reminding users to confirm suitability for their specific installation and accessory tests.

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
