Full title and description

St IEC 62067-2022 — Power cables with extruded insulation and their accessories for rated voltages above 150 kV (Um = 170 kV) up to 500 kV (Um = 550 kV) — Test methods and requirements. This edition defines the test procedures, acceptance criteria and requirements applicable to single-core cable systems with extruded insulation and their prefabricated accessories for fixed high-voltage installations.

Abstract

IEC 62067:2022 specifies type, prequalification, routine and sample tests and the associated requirements for power cable systems with extruded insulation and their accessories for rated voltages >150 kV up to and including 500 kV. It applies to single‑core cables and customary accessories under normal installation and operating conditions and excludes special applications such as submarine cables and transition joints between extruded‑insulation and paper‑insulated cables.

Scope

The standard covers test methods and requirements for power cable systems consisting of single‑core cables with extruded insulation and their accessories intended for fixed installations with rated voltages above 150 kV (Um = 170 kV) up to and including 500 kV (Um = 550 kV). It addresses electrical, thermal and mechanical tests used for type and routine verification, criteria for prequalification and extensions to prequalification, and requirements for prefabricated accessories (terminations and joints). Special cables (for example submarine cables) and transition joints to paper‑insulated cables are excluded and may require modified or separate test procedures.

Key topics and requirements

• Definitions of voltage designations and material requirements for conductors, screens and oversheaths.
• Test categories: routine, sample, type tests, prequalification and extension of prequalification.
• Electrical tests: partial discharge measurement criteria, AC withstand tests, impulse (lightning and switching) tests, heating‑cycle and temperature‑rise tests.
• Mechanical and environmental tests relevant to accessories: mechanical strength, sealing against water penetration and thermal cycling.
• Acceptance criteria and test voltage selection related to rated system voltage (Um) and operating conditions.
• Requirements and test procedures for prefabricated accessories (joints and terminations) matched to the cable system.

These topics summarise the principal technical content and testing requirements specified in the 2022 edition.

Typical use and users

IEC 62067:2022 is used by transmission system operators, cable manufacturers, testing and certification laboratories, engineering consultants, procurement teams and national standards/adoption bodies to specify, qualify and verify high‑voltage cable systems (150–500 kV) and their accessories for overhead‑to‑underground interfaces, long‑distance transmission and large industrial supply projects. It is also a reference for acceptance testing during manufacture, factory inspection and site commissioning.

Related standards

Relevant neighbouring standards include: - IEC 62067:2011 (previous edition) — the 2022 edition revises and replaces the 2011 edition; - IEC 62067:2022 RLV (Redline version) — shows technical changes versus the previous edition; - IEC 60840 — test methods and requirements for extruded‑insulation power cables for rated voltages above 30 kV up to 150 kV (adjacent voltage range and closely related test philosophy). These related documents are commonly referenced together when specifying HV cable systems across different voltage bands.
