Type of equipment

This standard applies to cast resin partitions pressurized with inert gases, for example sulfur hexafluoride or a mixture of gases such as sulfur hexafluoride and nitrogen used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is used principally for its dielectric and/or arc-quenching properties, with rated voltages

- 1 kV and up to and including 52 kV and with gas-filled compartments with design pressure greater than 3 bar (gauge)

- and with rated voltage 72,5 kV and above.

The partitions comprise pressurized barriers in electrical equipment not necessarily limited to the following examples:

circuit breakers,

switch disconnectors,

disconnectors,

earthing switches,

current transformers,

voltage transformers,

surge arrestors,

busbars and connections,

cable connections.

This standard does not apply to high-voltage bushings (see HD 358 S3 (IEC 517)).

Quality assurance

It is the intention of this standard that the switchgear manufacturer shall be responsible for achieving and maintaining a consistent and adequate quality of product.

Sufficient examinations shall be made by the partition manufacturer to ensure that the materials, production and testing comply in all respects with the requirements of this standard. Inspections by the users' inspectors shall not absolve the switchgear manufacturer from his responsibility to exercise such quality assurance procedures as to ensure that the requirements and intent of this standard are satisfied.

NOTE. Reference should he made to the EN 2900() series of standards for quality assurance systems.
