x 6mm. Line leads leading to the HV Bushing terminals shall be directly clamped to the

horizontal support bar of the "Pie" structure, so that any tension which may developed in the

HT Leads due to jerks or at the time of making the connection, is not passed to the HT Coils. It

would be preferable to use glass sleeves/SRBP tubes where-ever practicable on the leads taken

out from winding to terminals and bushings.

2.8 Delta joint and lead from delta joint to bushing rod shall be made by brazing only for HV

windings.

2.9 The LV connection shall be taken out by cut on the top yoke channel duly reinforced to

compensate for the mechanical strength.

2.10 LV star point shall be formed of aluminium flat for aluminium wound transformers and

copper flat for copper wound transformers of sufficient strength. Leads from winding shall be

connected to the flat by brazing.

2.11 Firm connection of LV Windings to bushing shall be made of adequate size of "L"shaped

flat. Connection of LV coil to "L" shape flat shall be by brazing only.

2.12 LT Aluminium / Copper lugs shall be clamped to LV bushing metal part by using nut, lock

nut and washer.

2.13 The winding shall be clamped securely and placed so that they will not be displaced or

deformed during short circuits. The conductors used in the coil structure shall be best suitable

to the requirement and all permanent current carrying joints in the windings and the leads shall

be brazed preferably and rigidly clamped.

3. CORE LAMINATION ( CRGO / AMORPHOSE MATERIAL):

3.1. After cleaning dust and dirt from each leaf of laminations, the core shall be rigidly clamped

and bolted to ensure adequate mechanical strength and to prevent vibrations during operation.

The bolts used in the assembly of the core shall be suitably insulated and clamping structure


shall be so constructed that eddy current will be minimum.

3.2 The core and the coil assembly shall be so fitted in the tank(s) that shifting may not occur and

original clearance is maintained when the transformer is moved/transported or during the short

circuit conditions.

4. FREQUENCY:

The repaired transformers shall be suitable for continuous operation with a frequency variation

of ± 3% from normal frequency of 50 cycles per second without exceeding permissible

temperature rise.

5. PARALLEL OPERATIONS:

The repaired transformers of the same capacity, type, voltage ratio and vector group shall be

suitable for parallel operation.

6. NO LOAD VOLTAGE:

The No Load voltage ratio of the repaired transformers shall be same as that of the original

transformer (11/0.433KV) with tolerance of ± 1%.

7. HIGHEST SYSTEM VOLTAGE :

The highest system voltage shall be as 12 KV on HT side. The repaired transformer shall be

suitable for continuous operation with this voltage on the HV side.

8. TRANSFORMER OIL:

8.1 The transformer oil will be drained out from the transformer before delivery to firm for repair

by the repairer.

8.2 Fresh/new EHV Grade transformer oil for filling in the repaired transformer(s) shall be

provided by the repairer and the quantity of new transformer oil, as may be required to be

filled in, shall be as per the quantity mentioned on the name plate of the transformer(s). The

make of EHV grade transformer oil shall be either APAR/SAVITA/RAJ

LUBRICANT/LUBRICHEM, MUMBAI / RAJ PETRO, MUMBAI / PANAMA

PETROCHEM, ANKALESHWAR/ TASHKANT OIL, MUMBAI /IOCL/HPCL or any other

equivalent make approved by the NESCO Utility. The EHV grade transformer oil shall be

duly filtered and tested and shall conform to the various technical parameters specified in

IS:335/1993 (latest amended).


8.3 NESCO Utility can also provide transformer oil for filling in the repaired transformer

depending upon the availability of the transformer oil in the store of the NESCO Utility. The

transformer oil as may be supplied by NESCO Utility shall be filtered and tested before filling

in the repair transformers.

9. PAINTING:

9.1 All metallic surface exposed to the weather and requiring painting shall be given one suitable

priming coat after derusting by sand/shot blast or chemical cleaning including phosphating as

per IS:3618 and one coat of thermo-setting powder paint or two coats of zinc-chromate

followed by two coats of synthetic anamel paint of dark admirally Grey shade confirming to

shade No.632 of IS:1961 shall be applied. The rates for one coat spray painting without primer

etc. shall also be quoted separately.

9.2 The inside of transformers shall be given suitable priming coat after derusting and two

finishing coats of heat resistant (hot oil proof) paint which may not cause any deterioration of

properties of the transformer oil by chemical reaction etc.

10. The tenderer have to submit the details of testing equipments with date of calibration available at their works as per the format enclosed as Annexure- I 11. The Tenders must be accompanied with proof of:-
