Dear Sir,

With reference to you above tender, we wish to draw your kind attention on the following our

technical query:

(A) The specification attached to the tender is SP-EWH2-3C-00, WHICH IS REVISION 00.

However, as discussed during last tender and order, Rev 01 of the specification is used,

which may be reviewed. Our comments in Rev 00 are as follows:

BRPL Clarification- R1, Uploaded.

Clause

No. Comments Justification

BRPL Clarifications

3.2

Grade of Aluminium

shall be h4 instead of

H2.

For H2 grade, the finished

conductor is subjected to that

treatment which is not

desirable for water sealed

conductor as the water

blocking tapes/yarn provided

inside the conductor will lose

its water swelling

characteristics under heat

treatment. Hence the

conductor shall be H4 grade.

Water blocking tape

required. H4 grade is

accepted.

3.6 Please delete words

"nor more" in 3rd line,

It specifies that minimum

thickness at any point shall not

be less or more than 10% of

the nominal value. The words

"or more " is irrelevant for

minimum thickness at any

point.

Value shall be as per tech

spec.

3.8

Add word "and semi

conducting

compound" in

between 'TR-XLPE' &

'OF'

The make specified are

required for insulation and

extrued semi-conducting

screen whereas TR-XLPE is

relevant only for insulation.

For longitudinal water barrier

one tape is sufficient. Hence

wprd tapes in these in these

clause should be either

amended to read as tape (s) to

avoid any confusion.

ok

3.14-si2

Delete Attenuation

test during Acceptance

testing

It is not practicable to test

attenuation on the cable

length such as 250/230 mtrs.

Hence the test shall be on Raw

materials during incoming

inspection.

required

3.15

Words "Polyethylene

ST7" to be replaced by

"PP"

To include PP fillers suitable

for the construction specified.

PP with water blocking

tape.

3.16

Add " A suitable binder

tape may be applied

over laid up assembly"

Binder tape over laid cores

assembly is generally desirable

to have compact assembly.

Hence there should be a

provision for optional binder

tape.

Binder tape mandatory.

3.17 Word "Pressure " to be

deleted.

This is required for the

specifies construction, so that

sleeve / tube extrusion shall

be offered.

ok

3.18 Review diameter of

armour wire

The clause specifies steel wire

diameter as Min. 4.0 mm

whereas at S.NO. 33 Annexure

C it has been specified as

Nominal. Please review.

Minimum 4 mm dia

armour wire.

5.3 & 5.4

Special test to be

reviewed to avoid

duplication

With exceptions to the

following tests called under

special tests is also part of

Acceptance tests.

A Degree of crosslinking

B. Void & contamintion

C. Abrasion resistance

D. Sheath integrity test

Further, since the rest

requirement for void &

contamination are deleted in

IS 7098 Pt. 3-93, a sample per

lot shall be subjected to this

test and observed value shall

be furnished for records only.

Part of acceptance test

also.

Sheath integrity test shall

be applied also after

laying of cable at site as

mentioned in tender

special terms and

conditions.

3.17 &

3.20

Amend IEC 60502 - 2

to read as IEC 60840

Since IEC 60840 shall been

referred for testing it would be

more appropriate to refer it

for material properties instes

of IEC 60502-2.

Ok.

(B) We confirm that sequential length marking shall be provided by printing/

indenting/embossing in contrast colour on outer sheath with progressive (sequential) length

of cable at every meter, however it may not necessarily start from zero for economic reason

otherwise every drum length of one cable has to be manufactured separately and in that

case the cumulative scrap will be huge, which will not be utilized to us as well as you. Hence,

to minimize this extra unusable expense, we will mark the length starting from any no as

found in the manufacturing length maintaining exact length per drum.

BRPL Clarification- every drum length shall start from zero

(C) Please arrange to send us detailed technical specs & GTP format for control cables.

W Where N = number of parallel wires / Strips d = diameter of wire / width of formed wires W = π x D x Cos a, D = diameter under armour a = angle between armouring wire / formed wires and axis of cable tan a = π x D/C, and C = lay length of armouring wires / formed wires. Min 90% armour coverage shall be provided both in case of wires and strips. The gap between armour wires / formed wires shall not exceed one armour wire / Formed wire space and there shall be no cross over / over-riding of armour wire / Formed wire.
