3.3.7 Immediately after completion of the electrical tests (during routine/ acceptance tests),
the ends of the cable shall be enclosed by rubber/ PVC caps of wall thickness not less
than 2.5mm and then sealed by non hygroscopic material (the cores being suitably
insulated from the cap). The cap shall be of robust construction and tight fit, and it
shall have the trade mark of the manufacturer embossed thereon.
3.3.8 All materials used in the construction of cable shall be new, unused and of finest
quality.

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

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
