GOST 16523-97 PDF

Full title and description

GOST 16523-97 — a Russian national standard specifying the terminology, definitions and general technical requirements for insulation-piercing (test) clamps and related connectors used in overhead power lines and communication cables. The standard sets classification, designation, constructional and performance requirements, as well as testing methods to ensure safe and reliable connections that pierce insulation without prior stripping.

Abstract

This standard covers insulation-piercing clamps (also called insulation-displacement or piercing connectors) intended to establish electrical contacts with insulated conductors used in overhead distribution networks and cable systems. It defines types, materials, mechanical and electrical performance requirements, marking, packing and acceptance tests to ensure that connectors provide durable, low-resistance joints while preserving conductor integrity and insulating properties.

Scope

GOST 16523-97 applies to insulation-piercing clamps and connectors intended for making electrical connections to insulated conductors without removing the insulation. It covers construction types for various conductor sizes and materials, performance requirements under mechanical load, corrosion resistance, thermal endurance and dielectric properties, as well as marking, packaging and inspection procedures. The standard is aimed at manufacturers, testing laboratories and purchasers of line fittings and accessories for power distribution and communications.

Key topics and requirements

• Definitions and classification of insulation-piercing clamps by design and application (single / multiple conductor, tap-off, repair, etc.).
• Constructional requirements: materials, contact geometry, protective coatings and sealing to ensure reliable border between conductor and environment.
• Electrical performance: permissible contact resistance, current-carrying capacity and temperature rise limits under rated loads.
• Mechanical performance: tensile and cyclic load resistance, retention on conductor and resistance to vibration and mechanical stress.
• Environmental and durability tests: corrosion resistance, insulation integrity, aging and thermal cycling.
• Marking, labelling and packaging requirements for traceability and safe storage/transport.
• Acceptance and type testing procedures, sample sizes and criteria for conformity assessment.

Typical use and users

Used by manufacturers of electrical fittings and connectors, utilities and contractors for overhead power distribution, telecommunication network installers, procurement specialists and testing laboratories. Typical applications include tapping service drops from live insulated conductors, making branch connections without stripping insulation, repairs and temporary connections in power and communications networks.
