IEEE P48/D7, Sep 2019

P48/D7, Sep 2019 is a technical standard focused on current cable terminations used on shielded cables with laminated insulation rated 2.5 kV through 765 kV or extruded insulation rated 2.5 kV through 500 kV. It is relevant to components, circuits, devices and systems in power and energy applications, where termination design can affect insulation performance, reliability, and safe operation. For engineers and buyers, this standard helps define the expected framework for cable termination selection and evaluation.

P48/D7, Sep 2019 overview

The purpose of P48/D7, Sep 2019 is to address current practices and technical requirements for cable terminations on shielded power cables within specified voltage classes. The standard’s subtitle points to a narrow but important scope: laminated and extruded insulation systems used in high-voltage service. In that context, the document may support consistent design review, specification writing, and comparison of termination solutions. It is a practical reference when working with insulated cable systems where termination details influence electrical integrity and long-term performance.

Typical use cases

This standard is typically used when specifying or reviewing terminations for shielded cables in power transmission and distribution equipment, underground cable installations, and utility-grade electrical assemblies. It is also relevant during engineering of terminations for systems using laminated or extruded insulation, where voltage rating and cable construction must match the termination method. Procurement teams, design engineers, and test personnel may rely on P48/D7, Sep 2019 to align component selection with the intended service conditions and installation requirements.

Why this standard matters

P48/D7, Sep 2019 matters because cable terminations are critical interfaces in high-voltage systems, and poor compatibility can create insulation stress, performance issues, or reliability risks. A clear standard helps support design control, consistency in purchasing, and more predictable testing or acceptance criteria. For organizations handling shielded cables across a wide voltage range, the document can reduce ambiguity when comparing products or validating designs. Using P48/D7, Sep 2019 may also help improve coordination between engineering, quality, and field installation teams.
