IEC 60840 Standards

Cable Joints | Terminations | Connectors | Bushings & Cables

The IEC 60840 Standards, created by the International Electrotechnical Commission, covers the requirements for LV MV HV Power Cables & Cable Accessories with operating voltages from 30kV (Um = 36kV) up to 150kV (Um = 170kV. Power cables and accessories in compliance with IEC 60840 are either single core or individually screened three-core cables. This Power Cable Standard is dedicated to applications which require high voltage electrical power transmission over longer distances, typically suitable for buried applications.

IEC 60840 Power Cable Applications

IEC 60840 High Voltage Cables are designed for fixed installations, with the purpose of high distribution of power. IEC 60840 compliant cables used in overhead lines or buried underground, cover key requirements to be suitable for these environments:

• Advanced material specifications to handle high voltages
• Construction requirements focused on managing electrical stresses
• Rigorous testing protocols, including partial discharge tests, ensuring long-term reliability
• Specifications for HV Cable Joints, Terminations & Connector accessories, suitable for high voltage environments

IEC Standard Cable & Acessories LV MV HV

IEC Standards (Power Cable Standards) are internationally recognized technical guidelines established by the International Electrotechnical Commission (IEC) to ensure the safety, reliability, and interoperability of electrical LV MV HV power cables, accessories and electronic devices and systems. These standards play a crucial role for technical requirements across borders, making sure that products meet high-quality benchmarks, are compatible with one another, and adhere to regulatory requirements. The scope of IEC Standards is broad, including a wide variety of technologies, from power generation, transmission, and distribution, to semiconductors, fibre optics, and renewable energy sources like solar and marine energy.

The development of IEC Standards involves a collaborative process where experts from various countries contribute to creating universally applicable guidelines. Some standards are developed jointly with the International Organization for Standardization (ISO) to further ensure consistency across industries and regions. These standards are adopted by countries around the world and often become national or regional benchmarks. In many cases, compliance with IEC Standards is used to certify that equipment, systems, or components meet internationally recognized safety and performance criteria.
