Описание (английский):

Specifies the test methods to be used for type testing accessories for power cables with rated voltage from 3,6/6 (7,2) kV up to 18/30 (36) kV. Test methods are specified for accessories for extruded and paper insulated cables according to IEC 60502-2 and IEC 60055-1 respectively. Significant technical changes with respect to the previous edition are as follows: a) a test in water has been added for stop ends; b) the heating cycles voltage test has been revised to clarify testing in air and water; c) the testing conditions for the short-circuit tests have been redefined; d) additional information has been provided for testing separable connectors with a metallic housing; e) tests not required by IEC, i.e. an immersion test for outdoor terminations and an impact test, have been included in order to have a common test method document with CENELEC under the IEC/CLC Dresden agreement.

Abstract

Overview

IEC 61442:2005 - Test methods for accessories for power cables with rated voltages from 6 kV (Um = 7.2 kV) up to 30 kV (Um = 36 kV) - defines the type-testing procedures used to verify electrical, thermal and mechanical performance of cable accessories. It covers accessories for both extruded and paper‑insulated cables (referencing IEC 60502‑2 and IEC 60055‑1). The 2005 second edition includes new and clarified tests (water immersion for stop ends, revised heating‑cycle rules, redefined short‑circuit conditions, guidance for metallic separable connectors, and additional immersion/impact tests aligned with CENELEC).

Key topics and requirements

Scope and applicability: Type tests for accessories used on cables rated from 3.6/6 (7.2) kV up to 18/30 (36) kV.
Voltage tests: AC and DC high‑voltage tests, impulse voltage tests, and tests at elevated temperatures.
Partial discharge: Procedures for partial discharge measurement in accordance with IEC 60270 and IEC 60885‑3.
Heating‑cycle voltage test: Clarified methods for testing in air and in water to simulate operational thermal cycling.
Short‑circuit tests: Thermal short‑circuit tests (screen and conductor), and dynamic short‑circuit testing with revised test conditions.
Environmental and mechanical tests: Humidity and salt‑fog, immersion (for outdoor terminations), impact test, operating force and operating eye tests.
Connector‑specific guidance: Additional information for separable connectors with metallic housings and stop‑end water tests.
Screen and leakage measurements: Screen resistance, leakage current, and screen fault current initiation methods.
Test apparatus and setup: Detailed installation, measurement, and method clauses for reproducible laboratory testing.

Practical applications and users

Who uses IEC 61442:

Cable and accessory manufacturers - for type approval and product development.
Independent test laboratories - to perform standardized type tests and report conformance.
Utilities and system integrators - to specify acceptance criteria in procurement and design.
Certification bodies and regulators - to assess compliance with international test methods.

Why it matters:

Ensures reliable performance of joints, terminations, separable connectors and stop ends under electrical, thermal and environmental stress.
Reduces field failures and supports safety and lifecycle planning for medium‑voltage distribution networks.
Harmonizes test methods internationally (including IEC/CLC Dresden agreement) to streamline cross‑market acceptance.
