GOST R 51155-2017 PDF

Full title and description

GOST R 51155-2017 — "Арматура линейная. Правила приемки и методы испытаний" / "Line accessories. Acceptance rules and test methods". The standard defines terminology, acceptance rules and test methods for line fittings (supporting, tension, connecting, contact, coupling, protective and repair fittings) used on overhead power lines and related equipment.

Abstract

GOST R 51155-2017 establishes requirements for sampling, acceptance criteria and laboratory/field test procedures for line accessories intended for overhead transmission and distribution lines with nominal voltages above 1 kV. The standard updates previous test methods, aligns certain procedures with international practice and replaced the older GOST R 51155–98 by order of Rosstandart.

Scope

This standard applies to line accessories (armature) for bare conductors and ground wires (shield wires) of overhead power lines with nominal voltage above 1 000 V. It may also be applied to accessories for insulated conductors, similar fittings for substations and accessories for aerial optical cables of overhead communication lines. The document sets definitions, acceptance rules and detailed test methods for the range of fittings listed.

Key topics and requirements

• Definitions and classification of line fittings (supporting, tension, connecting, contact, coupling, protective, repair, etc.).
• Rules and procedures for sampling and acceptance testing (type, sample and routine tests).
• Mechanical tests: breaking/load tests, slip tests, tensile tests and related mechanical performance verifications.
• Electrical and environmental tests where applicable (insulation-related checks, corona/RIV checks when relevant, corrosion resistance and climatic conditioning).
• Requirements for marking, documentation and traceability for delivered fittings.
• Updated or new test methods introduced to harmonize with international practice (references to IEC-type test procedures where applicable).

Typical use and users

Manufacturers of overhead-line fittings, component and hardware suppliers, testing laboratories, utility engineering departments, design institutes and certification bodies use this standard to verify product compliance, perform acceptance testing and to specify procurement acceptance criteria for fittings used on transmission and distribution networks.

Related standards

Closely related national and international standards include GOST R 51177-2017 (Line accessories — General technical requirements) and other IEC/ISO/industry standards covering specific test procedures and fittings (for example IEC standards on overhead-line fittings and insulators). The GOST text itself cites multiple normative references covering corrosion, climatic testing, materials and related mechanical/electrical tests.
