| 2.02PANEL The HT panel is rated at 6.6 KV, 3-Phase 800A, Breaking Current/short-circuit capacity of 26.3kA for 3 sec, 50c/s and shall be of floor-mounting, sheet steel clad, free-standing metal enclosed air insulated switchgear cubicle with VCB inside. The Vacuum Circuit Breaker (Make - Schneider Electric/SIEMENS/ABB/ Crompton Greaves/Pascal as approved by E.I.C) is horizontal isolation & horizontal drawout/Vertical isolation & horizontal drawout with 3 compartments and is made of 2mm CRCA sheet for load bearing members with vermin & moisture proof along with automatic shutter arrangement for complete isolation of bars, cable sockets & other live parts etc. when the removable portion is withdrawn. The breaker is arranged for hand operation through front of the panel push buttons & spring charging mechanism and also electrical motor which will be energizied by 230V AC. Closing and tripping coils are rated for 110V DC to be made available from local power supply 230 V, 50 Hz, A.C. with remote operation compatibility. All trip coils shall be of shunt trip type energized from a suitable rectifier condenser source.supply is required. There is a remote operation through multicore arrangement for closing & tripping. The shutter shall be gravity operated. | ||||||
| 2.03The switchgear and controlgear should have the minimum degree of protection (in accordance with IEC-60529 or as per Indian Standard IS 3427, as applicable( IP-4X for the enclosure and - IP-2X for the partition between compartments). | ||||||

| 2.05FRONT DOOR The front door of the breaker seting as panel door is not acceptable. High-Voltage door During switching operations, the high-voltage door should remain closed and mechanical interlock should prevent opening of door when the switching device is in service and is switched ON. The position of the withdraw-able section, the CLOSED/OPEN switch position of the switching device, the operating cycle counter and the “spring charged” indication should be visible through pressure-resistant inspection windows in the high-voltage door. The panel front door can be closed with the breaker in isolated position. | ||||||
| 2.06BUSBAR The spacious bus bar compartment is provided on the top of the cubicle. The main bus bar can carry current upto 1000A and are made of electrolytic grade copper & shall be vertically placed one after another. The bus bars should be air insulated but must be HT PVC sleeved & color coded for R-Y-B. No live parts should be accessible. All joints should be covered with monoplast compound and color coded for easy identification. The feeder connection to the busbars are preffered to be encapsulated. . | ||||||
| 2.07BREAKER The vacuum circuit breaker is mounted on a truck and is of horizontal isolation and horizontal drawout/Vertical isolation & horizontal drawout type having a robust motorized mechanism. The spring charge cycle duty of mechanism is O-C-O. The vacuum circuit breaker is single break design and have one vacuum interrupter per phase. The vacuum interrupter should not be of pinch tube type design, it should be sealed by brazing in a vacuum oven & all the vacuum interrupters must be segregated in a cast resin housing. The minimum operational life of the vacuum interrupter is 30,000 mechanical, 10,000 electrical at rated current & 100 at rated short circuit. The breaker is having auxiliary switch 6NO+6NC.. [OEM Certificate to be provided] | ||||||
| 2.08EARTHING A continous copper earth bus runs across the entire length of the switchboard. All doors partitions, covers and non current carrying metallic parts are earthed to achieve earth potential for the entire enclosure. Terminals are provided at each end of the earth bus to connect the grid earthing. If integral earthing facility is not available separate earthing truck shall be provided for earthing. | ||||||
