IEEE P1142/D1.1, Apr 2009

IEEE P1142/D1.1, Apr 2009 is a draft guide for the selection, testing, application, and installation of cables having radial moisture barriers and/or longitudinal water blocking. In the context of Power, Energy and Industry Applications, it supports engineering decisions where cable integrity and moisture resistance are important to system reliability. This technical document is useful for understanding how such cables may be specified, handled, and installed to help reduce water-related degradation in service.

Overview of IEEE P1142/D1.1, Apr 2009

IEEE P1142/D1.1, Apr 2009 focuses on cable systems designed with moisture-control features, including radial moisture barriers and longitudinal water blocking. The guide is aimed at practical selection criteria and field application concerns, with attention to testing and installation practices that can affect long-term performance. As a draft IEEE document, it is most relevant where design teams, procurement personnel, and installers need a common technical basis for comparing cable constructions and evaluating suitability for damp or water-exposed environments.

Typical use cases

This standard is typically consulted during specification and installation of power cables used in utility networks, industrial plants, and other energy infrastructure where moisture ingress can affect cable performance. It may be applied when reviewing cable constructions for underground runs, duct systems, or other installations with exposure to wet conditions. It can also support acceptance testing, product comparison, and project documentation for cable procurement where moisture-blocking features are part of the required design.

Why it matters

For projects that rely on moisture-resistant cable designs, IEEE P1142/D1.1, Apr 2009 helps bring consistency to selection, testing, and installation decisions. Clear guidance can reduce the risk of premature cable deterioration, service interruptions, and costly rework. It also supports better alignment between engineering specifications and field practices, which is especially important when evaluating performance claims or establishing procurement requirements. For teams working in power and industrial applications, that consistency can improve reliability and compliance.
