IEC 62895-2017 PDF

Full title and description

St IEC 62895-2017 — High voltage direct current (HVDC) power transmission — Cables with extruded insulation and their accessories for rated voltages up to 320 kV for land applications — Test methods and requirements. This International Electrotechnical Commission (IEC) standard specifies test methods and technical requirements for single-core HVDC power cables with extruded insulation and their associated accessories (joints, terminations, outdoor accessories) intended for fixed land installations up to and including 320 kV.

Abstract

IEC 62895:2017 defines the test procedures and performance requirements used to verify the electrical, mechanical and environmental behaviour of HVDC extruded-insulation cable systems and accessories for land applications up to 320 kV. It covers material definitions, sample preparation, type and routine tests, and special test conditions for joints and terminations used in transmission systems operating in direct current (DC) environments.

Scope

IEC 62895:2017 applies to transmission power cable systems comprising single-core cables with extruded insulation and their accessories for fixed land installations with rated voltages up to and including 320 kV. "Extruded insulation" includes thermoplastic and crosslinked polymeric insulations (for example PE, XLPE, EPR) whether filled or unfilled. The standard addresses normal installation and operation conditions for cables, outdoor terminations (including for gas-insulated systems), joints and asymmetric joints. It excludes special cable types (for example submarine cables) for which test modifications or special test conditions may be required.

Key topics and requirements

• Definitions and material characterization for extruded insulation and relevant conductor and sheath materials.
• Type tests and routine tests for cable cores, accessories, joints and terminations under HVDC stress conditions.
• Electrical tests including DC withstand, partial discharge measurements and impulse tests where applicable.
• Mechanical and environmental tests: aging, thermal cycling, bending, tensile, and water/impurity resistance relevant to long-term HVDC operation.
• Requirements and tests for accessories (joints, terminations) ensuring compatibility with cable system performance.
• Sample preparation, testing arrangements and acceptance criteria for manufacturers and test laboratories.
• Normative references to related IEC test-method standards (for example high-voltage measurement methods and non-metallic materials tests).

Typical use and users

Used by cable manufacturers, accessory (joint and termination) makers, testing laboratories, transmission system planners, consulting engineers and procurement/specification teams involved in HVDC land transmission projects. The standard is referenced in type approval, factory testing, contract specifications and performance verification for extruded-insulation HVDC cable systems up to 320 kV.

Related standards

IEC 62895:2017 is part of the family of IEC cable test standards and is commonly used alongside other IEC documents such as IEC 60840 (extruded-insulation power cables and accessories for up to 150 kV), IEC 62067 (extruded-insulation power cables for higher voltages), the IEC 60060 series (high-voltage test techniques), and the IEC 60811 series (tests for non-metallic materials). National adoptions exist (for example BS IEC 62895:2017) and regional versions may be published under EN/ISO adoption processes.
