IEC 60183:2015

Overview

IEC 60183:2015 is an international standard published by the International Electrotechnical Commission (IEC), providing guidance for the selection of high-voltage alternating current (A.C.) cable systems. It specifically addresses cables with extruded insulation used predominantly in three-phase A.C. systems operating at voltages exceeding 1 kV, classifying these as high-voltage cables. The standard excludes submarine cables, but covers cables laid in water environments.

This third edition, published in 2015, revises and replaces the previous 1984 edition and its 1990 amendment, reflecting important technical updates. It offers detailed recommendations on selecting conductor sizes, insulation levels, construction requirements, and accessories for optimum cable system performance. Additionally, the standard highlights relevant environmental factors that affect cable selection and application.

Key Topics

• Scope and Applicability: IEC 60183 focuses on extruded insulation high-voltage cables for A.C. systems above 1 kV, excluding paper-insulated and submarine cable systems. It emphasizes compatibility considerations when connecting new extruded cables with existing paper insulated cables.

• Cable Selection Criteria: The standard provides guidance on:

  • Choosing appropriate conductor sizes based on load requirements and thermal performance.
  • Determining the insulation level to withstand operational and transient voltages.
  • Meeting constructional requirements including mechanical and electrical properties.
  • Selecting suitable accessories such as terminations and joints, considering environmental influences like pollution, altitude, and water exposure.

• Operational Conditions: Factors impacting cable choice include installation environment (underground, aerial, water-laid), operating conditions such as system voltage levels, bonding of cable screens, and ambient temperature.

• Environmental Considerations: The standard addresses the impact of ecological factors on cable systems, reflecting growing global emphasis on sustainable infrastructure. It briefly discusses environmental management aligned with ISO 14000 to support environmentally responsible cable design and deployment.

Applications

IEC 60183:2015 is vital for engineers, designers, and procurement specialists involved in:

• Designing and specifying high-voltage power distribution and transmission networks.
• Selecting cables for industrial and utility-scale electrical infrastructure projects with operational voltages above 1 kV.
• Ensuring compatibility and safety when integrating new extruded insulation cables with legacy paper-insulated systems.
• Planning installations in varied settings including underground ducts, aerial spans, and cables laid in water (excluding submarine cables).
• Optimizing system reliability and longevity through proper cable and accessory selection given site-specific operational and environmental conditions.
• Achieving compliance with international standards for high-voltage power cables and reducing risk of failure or degradation.
