specified in IS:3961(Part-II)/1988 with latest amendment, if any. The rating factors

etc. under different conditions of installation shall also be furnished by the tenderers

so that rating of the cable under various conditions of installation may be determined.

3.4 INSPECTION, TESTING AND TEST CERTIFICATES:

3.4.1 The tenderer shall furnish an authenticated electrostat copy of type test results as

carried out on the same design to provide that the design has successfully passed

through required tests. The type test upto a maximum of 5 years prior to data of tender

opening by recognized test house of repute shall be acceptable.

If successful type test have been carried out on the offered design during last five

years (counted from the date of tender opening), repetition of type tests is not

required.

On the other hand, if the offered design is not type tested during last five years, the

cable shall be subjected to all type tests in accordance with IS:694/1977 and

amendment thereof, at recognised test house of repute. All charges/fee transportation

etc. to conduct these tests shall be borne by contractor.

Regular supply of the material shall commence only after successful type testing &

dispatch authorisation from competent authority.

However the purchaser reserves the right to get cable type tested at any stags during

the currency of contract at his own expenses in any reputed test house. The

transportation and arrangement of testing of sample to test laboratory shall be the

responsibility of the contractor.

3.4.2 In addition to routine test certificate of which shall be sent by the manufacturer with

their offer for inspection, the following acceptance test shall be carried out by the

inspecting officer's of the DVVNL on samples selected at random as per IS:694/1977

with latest amendments.

1. Test on Conductor Reference to ISS

a) Tensile test

b) Conductor resistance test

IS 8130/1984

IS 8130/1984

2. Test for thickness of insulation & sheet IS 5831/1970

3. Tensile Strength & elongation of Insulation & sheath IS 5831/1984

4. Insulation resistance test IS 5831/1970

5. High voltage test IS 1554(Part-I)/1988

In addition to above, length/weight check on one drum per inspection shall also be

carried out by the inspecting officers for which supplier shall make all necessary

arrangement and provide all necessary facilities at his own cast.

3.4 CABLE DRUMS:

3.5.1 The cables shall be supplied in non-returnable substantially lagged wooden drums of

heavy construction suitable for transportation by goods train or truck and for storage

at site. The wood used for construction of the drum shall be properly seasoned and

sound. Wood preservative shall be applied to the entire drum. All ferrous parts shall

be treated with a suitable rust preventive finish or coating to avoid rusting during

transit or storage. The drum shall also conform to Specification No. IS:10418-1982

with latest amendment thereof.

3.5.2 Each drum shall have the following information marked on it with indelible ink

alongwith other important information including technical data:—

1. Property of DVVNL.

2. Designation of consignee & destination railway station.

3. Drum Number.

4. Aluminium Core Cable.

5. Cable rating e.g. voltage grade, No. of cores, size etc.

6. Weight of empty drum.

7. Length of cable.

8. Gross weight of drum with cable.

9. Specification No. DVVNL-MM/……………

10. Year of manufacture.

The cable shall be supplied in standard drum length as given below:—

NORMAL CROSS SECTION OF CORES STANDARD DRUM LENGTH

3.5 × 70 Sq.mm 500meter ± 5%

3.5.3 Substandard drum length of net less than 100 meters upto a maximum of 5% of the

quantities ordered shall be accepted. However substandard drum length upto a

maximum of 5% shall be acceptable only in a particular let offered for inspection.

3.6 PACKING & TRANSPORT:

3.6.1 All the material covered under this specification shall be adequately packed for

transportation by Rail/Road. A layer of waterproof paper shall be applied to the

surface of the drums and over the outer cable layer. A clear space of atleast 40mm

shall be left between the cable and the laggings. The packing shall be adequate to

protect the cable from damage in transit. Supplier shall be responsible for the same

and make good at his own expense, any an all damage due to improper packing etc.

3.7 LITERATURE AND INSTRUCTION MANUALS:

3.7.1 The supplier is required to in invariably submit twelve copies of instruction manual,

descriptive bulletins and literature regarding the cable being ordered. These are

required to be submitted at the time of placing the order, directly to SE (Store),

DVVNL, Agra. The literature shall include amongst other the following

particulars:—

i) General Information.

ii) Principal technical data.

iii) Description of Insulation and sheathing.

iv) Installation and termination instructions.

4. RAW MATERIAL:

The supplier shall themselves be responsible for timely arrangement/ procurement of

all the raw-materials required for the manufacture of all ordered quantity of cable and

shall furnish their test certificates to the purchaser if so required.

5. VARIATION OF QUANTITY:

The supplied quantity can vary within Plus/Minus 1% of the ordered quantity.

6. The cable offered by the supplier shall conform to the requirement of IS:1554 Part-

I/1988 with latest amendments, if any, and as per technical particulars enclosed

herewith. No other technical particulars or deviations from technical particulars and

technical specification shall be accepted.

Further, these specification are subject to the technical terms and conditions

mentioned in General requirement of specification and DVVNL-Form 'B'. In case of

any ambiguity of Technical details given elsewhere the conditions given in Technical

Specification/Guaranteed Technical particulars shall prevail.
