IEC 60141-2:1963 pdf download,Tests on oil-filled and gas-pressure cables and their accessories – Part 2: Internal gas-pressure cables and accessories for alternating voltages up to 275 kV.
IEC 60141-2:1963 specifies test requirements for internal gas-pressure cables and their accessories intended for alternating-current systems with voltages up to 275 kV. Its purpose is to verify that the complete cable system, including joints, terminations, and other associated accessories, can operate safely and reliably under electrical, thermal, mechanical, and gas-pressure stresses.
The document addresses the construction and operating principles of cables whose insulation is maintained by pressurized gas within the cable enclosure or insulation system. It defines the tests, test sequences, applied voltages, pressure conditions, environmental conditions, and acceptance criteria used to assess insulation performance and system integrity. Particular attention is given to dielectric withstand, partial discharge or corona behavior where applicable, insulation resistance, losses, heating, pressure retention, leakage, and the ability of accessories to maintain effective sealing and electrical continuity.
The standard also provides a basis for type tests and, where relevant, routine or acceptance tests on manufactured cable lengths and completed installations. Test conditions are intended to represent service stresses, including normal operating voltage, overvoltage, temperature variation, and gas-pressure changes. Results should be recorded together with cable design, rated voltage, conductor arrangement, insulation system, pressure, accessory configuration, and test duration.
Overall, IEC 60141-2:1963 promotes uniform qualification and quality control of high-voltage internal gas-pressure cable systems, helping utilities and manufacturers confirm dependable performance, safe installation, and long-term insulation reliability in transmission networks.
