IEC 60055-2:1981/AMD1:1989

IEC 60055-2:1981/AMD1:1989 is a focused amendment to the paper-insulated metal-sheathed cable specification for rated voltages up to 18/30 kV, covering general and construction requirements for cables with copper or aluminium conductors. As a supporting document to the parent reference, it is relevant when engineering, procurement, or compliance teams need an updated technical basis for product review, documented evaluation, or conformity assessment. It helps clarify the construction expectations that underpin reliable cable selection and specification control in electrical infrastructure workflows.

Overview of IEC 60055-2:1981/AMD1:1989

This amendment is associated with the parent document IEC 60055-2:1981 and should be read as a modifying reference rather than a standalone technical code. Its scope is tied to paper-insulated metal-sheathed cables intended for medium-voltage service, excluding gas-pressure and oil-filled types. In practice, it is useful for technical review of cable construction, design consistency, and documentation checks where controlled interpretation of the parent requirements is needed. Organizations may use it to support engineering specification alignment and internal quality workflows.

Compliance applications of IEC 60055-2:1981/AMD1:1989

IEC 60055-2:1981/AMD1:1989 is typically consulted in product evaluation, procurement review, and laboratory evaluation for cable systems that fall within the stated voltage range. It can support testing workflows and compliance preparation where the construction details of paper-insulated metal-sheathed cables must be verified against an established reference. Utilities, cable manufacturers, test laboratories, and contractors may use it during technical validation, especially when preparing bid documentation, inspection criteria, or conformity assessment records for electrical equipment.

Importance of compliance with IEC 60055-2:1981/AMD1:1989

Using this amendment alongside the parent document helps maintain operational consistency in design and assessment decisions for medium-voltage cable assemblies. It can reduce risk in engineering documentation by improving clarity around construction requirements, which supports safety, interoperability, and test repeatability. For procurement and compliance teams, it provides a traceable technical reference for evaluation and approval activities, helping ensure that purchasing decisions and verification activities are based on a consistent interpretation of the cable construction requirements.
