Title
A.C. Insulation-Enclosed Switchgear and Controlgear for Rated Voltages Above 1 kV and up to and Including 38 kV

Appareilage sous enveloppe isolante pour courant alternatif de tension assignee superieure a 1 kV et inferieure ou egale a 38 kV

International Electrotechnical Commission

Publication Date:
Jan 1, 1987

Scope:

This standard specifies requirements for factory-assembled insulation-enclosed switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and including 38 kV for indoor installation, and for service frequencies up to and including 60 Hz.

Note. – In some countries the highest voltage for equipment is 40.5 kV.

Insulation-enclosed switchgear and controlgear for special use, for example in flammable atmospheres, in mines or in ships, may be subject to additional requirements.

This standard does not deal with components contained in insulation-enclosed switchgear and controlgear for which individual specifications exist.

Notes 1. – Switchgear and controlgear assemblies having a metal enclosure are covered by IEC Publication 298: A.C. Metal-enclosed Switchgear and Controlgear for Rated Voltages above 1 kV and up to and including 72.5 kV.

2. – While this standard also covers insulation-enclosed switchgear and controlgear the insulation of which is an insulating fluid other than air at atmospheric pressure, additional requirements for such equipment may apply depending on its design.

For the purpose of this standard, when the term “switchgear” is used alone, it corresponds to “insulation-enclosed switchgear and controlgear”.
