ELECTRICAL 11kV SWITCHGEAR
- Description: This specification covers the design and manufacture of 11kV metalclad switchgear for ring main applications, complete with all accessories. Switchgear shall be designed and manufactured to IEC 62271-200 or other approved standards to meet the latest Abu Dhabi Distribution Company (ADDC) specifications. It is mandatory for manufacturers to have valid ISO 9000 series Certification issued by an internationally-recognised agency in Western Europe, USA or Japan, and should have been tested in a "Recognised Independent Testing Laboratory" as per the relevant IEC standards, including "Short Circuit Withstand Tests". The Manufacturer shall have documented supply record of similar switchgear working satisfactorily in the same climatic and service conditions for the last five (5) years as a minimum prerequisite to submit their offer. Evidence of type testing, together with copies of test certificates from a recognised independent short-circuit testing station covering the equipment offered, shall be submitted. The type-test evidence shall show that the circuit breakers have been tested in their cubicles and that all current carrying parts of these cubicles (busbars, isolating connections, current and voltage transformers, cable termination chambers, etc.,) have been included for all tests required by the relevant IEC standard. If additional independent type testing is required to fully comply with IEC recommendations, the additional time required for full type testing shall not relieve the Contractor of his obligations to complete the Works within the Contract time for completion. Additional type testing, if required, shall be performed at no extra cost to ADSSC and the Contractor shall in addition bear all costs in connection with the witnessing of such tests by ADSSC. The switchgear shall be installed in a non-air-conditioned room without any forced ventilation duty at the ambient conditions specified in Section 15001: General M&E Requirements.
