IEC 60055-2:1981

IEC 60055-2:1981 addresses paper-insulated metal-sheathed cables for rated voltages up to 18/30 kV, focusing on general and construction requirements. For engineers, buyers, and compliance teams, it provides a technical reference for evaluating cable design expectations before specification, procurement, or conformity assessment activities. IEC 60055-2:1981 is relevant where medium-voltage cable systems must be reviewed for documented evaluation, construction consistency, and alignment with electrical infrastructure requirements. As part of an original technical reference, it supports clearer engineering documentation and more controlled quality workflows.

What is IEC 60055-2:1981?

This document defines the general and construction requirements for paper-insulated metal-sheathed cables using copper or aluminium conductors and excluding gas-pressure and oil-filled cables. It is intended to guide technical review of cable construction characteristics and to support engineering validation against a recognized compliance reference. In practice, it helps organizations compare product documentation, confirm design intent, and align procurement or laboratory evaluation activities with the expected cable type and voltage range. The scope is narrowly focused on construction-related requirements rather than broader system design.

Applications of IEC 60055-2:1981

The reference is commonly used in medium-voltage cable procurement, utility specifications, project engineering documentation, and product evaluation for power distribution installations. It may also support testing workflows, supplier qualification, and regulatory preparation where paper-insulated metal-sheathed cables are being assessed for conformity to a defined construction basis. Laboratories and inspection teams can use it to structure verification activities around cable type identification, build consistency, and documentation review. It is most relevant where electrical equipment selection depends on a controlled technical specification.

Why is IEC 60055-2:1981 important?

Clear construction requirements help reduce ambiguity during specification, manufacturing review, and acceptance checks. For organizations managing safety, interoperability, and technical compliance, IEC 60055-2:1981 provides a stable basis for comparison across suppliers and projects. It can improve testing consistency, support documented evaluation, and strengthen conformity assessment preparation by defining what the cable construction should address. In procurement and quality assurance workflows, that consistency lowers risk and helps teams validate whether the supplied product matches the intended engineering specification.
