conditions.

4.2 All equipments shall also perform satisfactorily under various other

electrical, electromechanical and meteorological conditions of the site

of installation.

4.3 All equipment shall be able to withstand all external and internal

mechanical, thermal and electromechanical forces due to various

factors like wind load, temperature variation, ice & snow, (wherever

applicable) short circuit etc for the equipment.

4.4 The bidder shall design terminal connectors of the equipment taking

into account various forces that are required to withstand.

4.5 The equipment shall also comply to the following:

a) All outdoor EHV equipments except marshalling kiosks shall be

suitable for hot line washing.

b) To facilitate erection of equipment, all items to be assembled at

site shall be match marked.

c) All piping, if any between equipment control cabinet/ operating

mechanism to marshalling box of the equipment, shall bear

proper identification to facilitate the connection at site.

4.6 Operating times of circuit breakers, protective relays and PLCC

equipment have been specified in respective sections. However, the

bidder is allowed to have minor variations on the individual equipment

timings subject to the condition that overall fault clearing time remains

within 100 milli seconds at 400 kV and 160 milli seconds at 220 kV

level under comparable conditions.
