Overview

IEC 62067:2001/AMD1:2006 is an important amendment to the international standard covering power cables with extruded insulation and their accessories. It specifies the test methods and requirements for cables rated for voltages above 150 kV (Um = 170 kV) and up to 500 kV (Um = 550 kV). Prepared by IEC Technical Committee 20 (Electric cables), this amendment enhances the original 2001 standard by clarifying test procedures and updating technical specifications to ensure the reliability and safety of high-voltage power cables in demanding environments.

This standard is crucial for manufacturers, engineers, and testing laboratories involved in the design, production, and quality assurance of extruded high-voltage power cables and accessories. It does not cover transition joints between extruded-insulation cables and paper-insulated cables, which are addressed by separate standards.

Key Topics

  • Scope Clarifications: This amendment explicitly excludes transition joints between extruded insulation cables and paper-insulated cables from the scope.
  • Test Voltage Frequency Range: Specifies the acceptable frequency range for alternating test voltages to be between 49 Hz and 61 Hz unless otherwise stated.
  • Cable Oversheath Requirements: Updates minimum thickness formulas for cable oversheaths, including lead or lead alloy and aluminium sheaths, ensuring adequate mechanical protection.
  • Metallic Screen Resistance: Requires the declaration of the d.c. resistance of the metallic screen for improved electrical performance characterization.
  • Type Test and Prequalification: Refines terminology and documentation requirements, emphasizing the importance of type test certificates and prequalification test certificates.
  • Test Procedures Updates:
    • Bending tests at ambient temperature with specific sample handling.
    • Heating cycle voltage tests with provisions for additional thermal insulation if target temperatures are not met.
  • Test Piece Preparation: Details on preparing test samples so that interfaces intended to be watertight are exposed properly, ensuring accurate water resistance testing.
  • Normative References: Includes reference to IEC 60840:2004 for cables rated between 30 kV and 150 kV, ensuring consistency across related standards.

Applications

IEC 62067:2001/AMD1:2006 is widely used in the power transmission and distribution industry for:

  • Designing and manufacturing extruded insulation cables for high voltage overhead and underground power networks.
  • Defining quality and safety benchmarks for cable accessories, such as joints and terminations used in high-voltage systems.
  • Conducting type testing and prequalification testing to guarantee compliance with international electrical and mechanical performance requirements.
  • Supporting asset management and failure prevention by ensuring cables withstand mechanical stress, environmental conditions, and electrical tests.
  • Facilitating regulatory and procurement specifications for utilities and contractors focusing on high voltage cable projects.

Related Standards

  • IEC 60840:2004 – Power cables with extruded insulation and their accessories for voltages above 30 kV up to 150 kV; sets test methods and requirements for cables operating at lower voltage ranges than IEC 62067.
  • IEC 61935 Series – Related to testing of joints and accessories for extruded power cables, complementing cable standards.
  • IEC 60287 – Applies to current ratings of cables; useful for design and operational performance considerations.
  • IEC 60502 – Covers power cables with extruded insulation for rated voltages up to 30 kV; provides foundational design and test insights.

This amendment enhances the reliability, durability, and safety assurance of high-voltage extruded insulation cables. Stakeholders involved in specification, manufacturing, testing, and installation will benefit from adopting IEC 62067:2001/AMD1:2006 to comply with current global best practices and technical requirements.
