IEC 60092-350:2014

IEC 60092-350:2014 Standard Overview

IEC 60092-350:2014 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the general construction requirements and test methods for power, control, and instrumentation cables used onboard ships and offshore units. These cables are designed specifically for fixed electrical systems operating at voltages up to and including 18/30(36) kV. The standard plays a critical role in ensuring the safety, reliability, and performance of electrical installations in maritime and offshore environments, which face unique operational challenges such as exposure to harsh conditions and mechanical stresses.

This standard excludes optical fiber, subsea and umbilical cables, data and communication cables, and coaxial cables, focusing strictly on copper conductor cables for shipboard and offshore applications.
