Full title and description

STB VDE 0212-307 E DIN EN IEC 63248 2020-01 — Conductors for overhead lines: Coated or cladded metallic wire for concentric lay stranded conductors. This document groups wire types with similar characteristics and specifies test procedures, material designations and requirements for metallic wires used as components of concentric-lay stranded conductors for overhead power lines.

Abstract

This standard (published as EN IEC 63248 / adopted as VDE 0212-307) defines the types, designations, required mechanical and electrical properties, and test methods for coated or cladded metallic single wires intended for use in concentric-lay stranded conductors for overhead lines. It consolidates and replaces earlier wire-specific standards and adds new wire materials and designation groupings to cover modern conductor designs.

• Publication date: 2020-01 (original EN IEC 63248:2020-01); consolidated German/EN adoption dated 2023-05 (DIN EN IEC 63248 / VDE 0212-307:2023-05).
• Publisher: IEC (as EN IEC at European level) / adopted and published nationally by DIN and VDE (VDE 0212-307).
• ICS / categories: Power transmission and distribution lines; electrical wires and cables (ICS references commonly given as 29.060.10 and related 29.240.20 classifications).
• Edition / version: E DIN EN IEC 63248:2020-01 (original edition); replaced by DIN EN IEC 63248 (VDE 0212-307) published May 2023 (EN IEC 63248:2022 + A11:2022 as adopted).
• Number of pages: 2020 edition — listed around 49 pages; 2023 consolidated German adoption — listed 51 pages.

Scope

The standard applies to metallic wires with single-wire diameters typically in the range of about 1.25 mm to 5.50 mm that are coated or cladded before stranding, intended either as complete concentric-lay stranded conductors for overhead power lines or as cores for such conductors. It specifies wire type groupings, material and coating categories, required mechanical and electrical properties, sampling and test methods, and informative annex values for calculations. The 2023 consolidated edition further harmonises designations and adds new wire types while removing obsolete coating classes.

Key topics and requirements

• Definitions and designation system for coated and cladded metallic single wires used in concentric-lay stranded conductors.
• Material groups covered (examples: aluminium-clad wires, cladded steels, zinc/aluminium alloy coated steels and other coated metallic wires).
• Mechanical properties (tensile strength, elongation) and dimensional tolerances for single wires.
• Electrical properties and calculation values for conductor design (annex values for calculations).
• Required type, routine and acceptance tests (visual, mechanical, coating/adherence and corrosion-related tests).
• Sampling procedures, labelling and marking, and product documentation requirements.
• Updates in later edition: regrouping of wire designations, removal of obsolete coating classes and addition of new materials (e.g., aluminium-clad FeNi36 types, extended zinc–aluminium alloys).

Typical use and users

Manufacturers of overhead conductors and wire, transmission and distribution utilities, conductor designers and engineers, material and test laboratories, procurement officers and certification bodies use this standard when specifying, producing, testing and qualifying coated or cladded metallic wires for use in concentric-lay stranded overhead conductors. It is used both for new-construction specifications and for replacement/repair material selection.

Related standards

Replaces or consolidates content from earlier documents such as EN 50189 and EN/IEC 61232 series; related standards include previous national/adopted standards on zinc-coated steel wires and aluminium-clad wires and companion standards covering conductor testing and overhead-line components. The consolidated 2023 edition is published as EN IEC 63248:2022 + A11:2022 and adopted nationally as DIN EN IEC 63248 / VDE 0212-307:2023-05.

FAQ

Q: What is this standard?

A: It is EN IEC 63248 (adopted as VDE 0212-307) — a standard that specifies coated or cladded metallic single wires used in concentric-lay stranded conductors for overhead power lines. The designation in national systems appears as VDE 0212-307 / DIN EN IEC 63248.

Q: What does it cover?

A: It covers wire type definitions and designations, required mechanical and electrical properties, dimensional tolerances, sampling and test methods, and values for conductor calculations — for wires coated or cladded before stranding and intended for use in concentric-lay stranded overhead conductors.

Q: Who typically uses it?

A: Wire and conductor manufacturers, transmission/distribution utilities, design engineers, test laboratories, certification bodies and procurement/specification teams.

Q: Is it current or superseded?

A: The EN IEC 63248:2020 (as referenced in the title) was the earlier edition; the consolidated and currently referenced adoption in Germany is DIN EN IEC 63248 / VDE 0212-307 published May 2023. The 2020 listing is shown as withdrawn/replaced in favour of the later consolidated edition. Users should reference the 2023 adoption for the most up-to-date requirements.

Q: Is it part of a series?

A: Yes — EN/IEC series of standards covering conductors and wires for overhead lines; it consolidates and updates material previously covered by standards such as EN 50189 and IEC/EN 61232. The document also exists alongside other IEC/EN documents that address full conductor specifications, fittings and testing for overhead-line systems.

Q: What are the key keywords?

A: Overhead conductors, coated/cladded wire, concentric-lay, aluminium-clad, zinc-aluminium coating, wire designation, VDE 0212-307, EN IEC 63248.
