GOST 34834-2022 PDF

Full title and description

GOST 34834-2022 — Power cables with extruded insulation for rated voltages from 6 up to and including 35 kV. General specifications. The standard establishes technical requirements, constructional characteristics and test methods for stationary power cables with extruded (plastic) insulation intended for AC networks with a rated frequency of 50 Hz and nominal voltages in the 6–35 kV range.

Abstract

This intergovernmental (GOST) standard defines general specifications for medium-voltage power cables with extruded insulation (typical insulating materials: XLPE / cross-linked polyethylene or similar polymers), covering conductor types (copper or aluminum), screens, bedding, armouring options and outer sheath materials, plus required electrical, thermal and mechanical tests, marking and documentation. It is aligned where practical with relevant IEC documents for extruded-insulation power cables.

General information

• Status: Sources are inconsistent — some databases list the standard as active while other commercial listings show it marked as withdrawn in mid‑2023; check the national registry for final legal status before relying on the standard for conformity/certification.
• Publication date: Designation year 2022; publication/implementation entries in commercial catalogues vary (examples show 01.01.2023, 01.07.2023 and 01.09.2024) — confirm the exact official entry date with the issuing authority.
• Publisher: Gosstandart of Russia / Federal Agency on Technical Regulating and Metrology (Russian standards system — GOST).
• ICS / categories: Electric cables and accessories — typically classified under ICS 29.120 (electric cables and conductors) / closely related to 29.120.10 in practice; related IEC references include the IEC 60502 series.
• Edition / version: Edition designated by number GOST 34834-2022 (most vendors list a 49-page document); note that some catalogues indicate later amended electronic releases.
• Number of pages: 49 pages (commonly listed in standards resellers' metadata).

Scope

The standard applies to stationary power cables with extruded plastic insulation intended for transmission and distribution of electrical energy at rated AC voltages from 6 kV up to and including 35 kV (rated frequency 50 Hz). It covers conductor and insulation constructions, screens and sheaths, armour options, selection of materials, marking and routine and type test requirements to verify electrical, thermal and mechanical performance for safe operation in normal service conditions.

Key topics and requirements

• Rated voltage classes and definitions (6 kV up to 35 kV) and corresponding electrical stress criteria.
• Conductor materials and geometries — solid/stranded copper or aluminum conductors and associated conductor cross‑section specifications.
• Extruded insulation requirements (typical materials such as XLPE), thickness, manufacturing tolerances and quality requirements.
• Screens and semiconductive layers, conductor and core screens, and earth/neutral conductor arrangements.
• Sheath and armour options (PVC, low‑smoke halogen‑free compounds, steel wire or tape armour, aluminium tape options) and environmental/climatic suitability.
• Type and routine tests: electrical (AC withstand, partial discharge), thermal ageing and current‑rating tests, mechanical (tensile, elongation), and fire/smoke/emission classifications where specified.
• Marking, documentation and declaration of conformity requirements for manufacture, shipment and installation.
• References and harmonization notes to IEC standards (notably IEC 60502 series) and related regional GOST documents for accessories (e.g., cable joints and terminations).

Typical use and users

Intended users are cable manufacturers, power utilities, design engineers, procurement specialists, test laboratories and certification bodies involved with medium‑voltage distribution and transmission projects (industrial, utility and infrastructure). Typical applications include underground and indoor power distribution, cable lines in substations and feeder circuits rated up to 35 kV.

Related standards

Commonly related standards and documents include the IEC 60502 series (power cables with extruded insulation), national GOSTs for accessories and joints (for example, GOST 34839-2022 for cable joints/terminals), and other GOST/technical conditions governing test methods and safety requirements for medium‑voltage equipment.

FAQ

Q: What is this standard?

A: It is a GOST intergovernmental standard (designation 34834-2022) that sets general specifications for power cables with extruded insulation rated from 6 up to and including 35 kV for stationary installations.

Q: What does it cover?

A: The document covers constructional requirements (conductors, insulation, screens, armour, sheaths), manufacturing tolerances, marking and a programme of type and routine tests (electrical, thermal, mechanical and environmental) needed to demonstrate compliance for medium‑voltage extruded‑insulation cables.

Q: Who typically uses it?

A: Cable manufacturers, design and commissioning engineers, utilities, test laboratories and conformity assessment bodies that manufacture, specify, test or certify MV cables and their accessories.

Q: Is it current or superseded?

A: Publicly available commercial listings show inconsistent status: some list the standard as active (with later electronic releases noted), while other catalogues mark it as withdrawn in mid‑2023. Users should confirm the current legal status and any amendments directly with the national standards body or official registry before using it for certification.
