General layout and transportation system; Access roads at the site

 

Existent SS-330/110 kV «October» is located in town Kiev in the street Stecenka 1a. Dwelling building is from every quarter located substation. SS has a long term of exploitation, as a result of which the set equipment is moral and physically outdated and requires replacement.

 

Placing of new buildings is determined the terms of existent SS and technological connections with OSS. Version of reconstruction does not require expansion of territory of substation.

 

From a north side to the ground of substation an entrance motorway calls with concrete coverage. Reconstruction existing OSS(Outdoor switching substation) -330 kV, OSS-110 kV planned within the limits of existent ground of SS.

 

Relief of ground is in the places of implementation of works – quiet. Absolute marks hesitate within the limits of 173,5 – 177m.

 

In connection with building of new buildings dismantling of part of existent protection of SS and building of new is foreseen.

 

Inspection and tests

All equipment and materials used for contractual works shall be factory-inspected and factory-tested, according to the requirements of the codes and standards.

 

The Employer's representatives may witness the inspection and tests of the equipment and materials. The Contractor shall notify the Employer on the time of inspection and tests of the equipment as per the procedure stipulated in the Contract.

 

Factory tests and factory test reports

 

The factory-build structures and equipment shall be completely assembled, adjusted and inspected at manufacturer's factory.

 

Simultaneously with delivery of the equipment, the Contractor shall submit to the Employer the factory test reports, which confirm the quality and technical characteristics of the equipment.

 

The Contractor shall ensure compliance of factory test reports, certificates and other necessary documentation delivered with equipment, with the requirements of the current Ukrainian codes and standards.

 

The Contractor shall bear all cost of the FAT.

 

 

Site tests

 

After installation of the equipment, the Contractor shall perform setting-up, checking, tests and commissioning of the equipment according to the programs agreed with the Employer.

Fire safety

GIS 330 kV and 110 kV on SS projected for the I degrees of fire-resistance. Gis 330 kV and 110 kV concordantly NAPB 06.015-2006, category on explosive and fire hazard of apartments - "D". For every building there must be no less than two outputs. Width of passage-ways for the ways of evacuation is accepted no less than a 1,0 m, width of doors - no less than 0,8 m.

 

In the apartment of storage batteries SCR, the pressurized accumulators, selecting the very negligible quantity of hydrogen in the mode of subcharge and boosting battery, are set. Taking into account permanent operating system of natural reveal-drawing ventilation and dissolution of concentration of hydrogen, this concentration can not attain explosive indexes. The apartment of storage batteries is subsumed «D».

 

External fire-fighting system is provided from existing on SS of the circular plumbing with fire-cocks.

Internal fire-fighting system from fire faucets is not used. For apartments foreseen only primary facilities of fire-fighting.

 

The gasket of cable is executed taking into account the requirements of gl.2.3 PUE. Concordantly NAPB 05.031-2010 in cable trays through 50 m, and also in the places of branches fire-prevention belts are foreseen from sand.

 

Fireproof cable passage-ways are foreseen through build constructions with the limit of fire-resistance no less EI60, compression of openings round pipes, cables - with the limit of fire-resistance no less EI60 concordantly p.3.16 SNiP 3.05.06.-85, p.10.5 NAPB V.01.056-2005/iii.
