Full title and description

ГОСТ 839-2019 — Провода неизолированные для воздушных линий электропередачи. Технические условия. (English: GOST 839-2019 — Non-insulated conductors for overhead power lines. Specifications.)

Abstract

Standard that sets technical requirements, constructional and performance characteristics, test methods, marking and acceptance rules for non‑insulated conductors (copper, aluminium, aluminium‑alloy and steel‑aluminium) used in overhead power transmission lines, replacing the earlier ГОСТ 839‑80. It includes provisions for modern conductor types (high‑temperature aluminium alloys, improved steel‑aluminium designs) and harmonises certain test methods with international practice.

Scope

This standard applies to non‑insulated conductors (wires) twisted from round wires — including copper, aluminium, aluminium alloys and steel‑aluminium conductors — intended for transmission of electric energy in overhead power lines. It establishes requirements for conductor construction, nominal geometric and electrical parameters, mechanical and thermal properties, methods of sampling and testing, marking, packing and acceptance rules for use in overhead lines (including lines at higher voltages and modern conductor designs).

Key topics and requirements

• Definitions and classification of conductor types (copper, aluminium, aluminium‑alloy, steel‑aluminium and variants for high‑temperature operation).
• Constructional parameters: strand count, wire diameters, core options (homogeneous, steel‑core, aluminium‑clad steel), and tolerances.
• Electrical and mechanical properties: nominal cross‑section, conductor resistance, breaking load, elongation, and permissible operating temperatures.
• Requirements for modern alloys and high‑temperature conductors (e.g., aluminium‑zirconium and high‑strength 6101/6201 alloys) and improved steel‑aluminium variants.
• Test methods and type/acceptance testing procedures (including references and alignment with international test methods such as IEC 61089 where applicable).
• Marking, documentation, packaging and rules for conformity assessment and acceptance sampling.

Typical use and users

Used by overhead line designers, power utilities, cable and conductor manufacturers, testing laboratories, procurement and quality departments, regulators and standards bodies involved in specification, production, testing and acceptance of bare conductors for transmission and distribution overhead lines.
