Overview

EN 61235:1995 (adopted as SIST EN 61235:2001) is a European adoption of IEC 61235:1993 (amended) published by CLC. The standard covers insulating hollow tubes made of synthetic materials intended for tools and equipment used in live working on electrical systems operating at voltages above 1 kV. It sets out the scope and requirements that help ensure safe use of hollow insulating tubes for working on energized equipment.

Key Topics

The standard addresses the principal technical aspects required to ensure safety and performance of insulating hollow tubes for live working. Core topics include:

  • Scope and definitions for insulating hollow tubes intended for live-line work above 1 kV.
  • Material considerations, specifying the use of suitable synthetic insulating materials (selection and expected properties).
  • Design and dimensions, covering tube geometry and construction appropriate for insulating tools and accessories.
  • Electrical insulation requirements, ensuring adequate dielectric performance for live working applications.
  • Mechanical performance, including strength and durability expectations during normal use.
  • Marking and identification, requirements for durable markings that indicate compliance, rated voltage range, manufacturer and relevant information.
  • Testing and conformity, general provisions for type and routine tests to verify safety and performance (as aligned with IEC/EN practices).

Note: This summary lists the standard’s main technical topics at a high level; consult the full EN 61235 text for specific test methods, limits and procedural details.

Applications

EN 61235 is used to ensure safety and compatibility of insulating hollow tubes in live working contexts. Typical applications and users:

  • Manufacturers of insulating tubes and live-line tools (design, product development, quality control).
  • Electrical utilities and contractors performing maintenance or live-line work on high-voltage systems (>1 kV).
  • Safety officers and procurement teams specifying compliant insulating equipment.
  • Testing and certification bodies assessing conformity to European/IEC live-working equipment requirements.

Practical use cases include insulated extensions, protective sleeves, and hollow insulating components integrated into tools for overhead line work and substation maintenance.

Related standards

  • Identified as identical with IEC 61235:1993 (as amended) and adopted regionally (e.g., SIST EN 61235:2001).
  • Commonly used alongside other IEC/EN standards governing live working equipment and electrical safety; consult the full standards framework when specifying complete live-working systems.
