FOREWORD

This Indian Standard ( Part 4/See 2 ) ( First Revision ) was adcpted by the Bureau of IndianStandards, after the draft finalized by the Wiriding Wires Scctio~al Committee had been approvedby the Electro[echuical Division Council.

This standard was originally published in 1978 covering PVC insulated winding wires forsubmersible moto)s for 85°C operation. Two other standards on winding wires for submersiblemotors, namely, 1S 10051 : 1981 ‘Specification for PVC ilisulated winding wires for submersiblemotors for 105”C operation’ and IS 12788 : 1989. ‘Specification for PVC insulated winding wiresovercoated with nylon for submersible motors’ have also been in vogue.

In the recent past there has been demand from the industry to make comprehensive revision ofthe existing standards on winding wires for submersible motors and also to include other types ofinsulation which are being extensively used in manufacture of winding wires for submersiblemotors. In view of this the new series of winding wires standards for submersible motors is beingbrought out as follows:

IS 8783 Winding wires for submersible motors — Specification

( J’art 1 ) :1995 Conductor data

( Part 2 ) :1995 Materials for dielectric and jacket

( Part 3 ) :1995 Methods of tests( Part 4/See 1 ) :1995 Specification for individual wires, Section 1 HR PVC insulated

winding wires

( Part 4/See 2 ) :1995 Specification for individual wires, Section 2 Crosslinked poly.ethylene insulated and polyamide jacketed wires

( Part 4/See 3 ) :1995 Specification for individual wires, Section 3 Pclyester andpolypropylene insulated wires

With the publication of these standards the requirements of PVC insulated wires will be coveredin Part 4/See I of this series, and two new types of insulation, namely, XLPE insulated andpolyester and polypropylene insulated wires have also been covered in this series.

For the purpose of deciciing whe[her a particular requirement of this standard is complied with,the final value, observed or calculated, expressing the result of a test, shall be rounded off inaccordance with 1S 2: 1960 ‘Rules for rounding off numerical values ( revised )’. The nhmberof significant places retained in the rounded off value should be the same as that of the specifiedvalue in this standard.

(First Revision)

1 SCOPE

1.1 This standard ( Part 4/See 2 ) covers therequirements of high conductivity annealed solidand stranded copper conductor, crosslinkedpolyethylene ( hereafter referred as XLPE )insulated and overall polyamide ( hereafter’referred as PA ) jacketed winding wires for sub-mersible motors.

1.2 The wires covered in this standard aresuitable for use where combination of ambienttemperature and temperature rise due to loadresults in conductor temperature not exceeding105”C under normal operation.

3 GENERAL

3.1 Conductor for this type of wires shall con-form to IS 8783 ( Part 1 ) :1995.

3.2 Dielectric and jacket material shall conformto Type 2 of IS 8783 ( Part 2 ) :1995.

3.3 Tests shall be carried out in accordancewith IS 8783 ( Part 3 ) :1995.

4 REQUIREMENTS

4.1 Thickaess of Insulation

The minimum thickness of insulation shall notbe less than the minim urn value (ti) specified inTable 1 or Table 2 as relevant.

4.2 Application of Insulation and Jacket

The insulation and jacket shall be so appliedthat it fits closely on the conductor and it shallbe possible to separate them individually.

4.3 Colour

The colour of insulation and jacket of windingwire shall be natural.

4.4 Overall Diameter

The overall diameter of winding wire shall notexceed the maximum value specified in Tables 1and 2.

4.5 The overall surface of finished winding wireshall be reasonably smooth.

4.6 High Voltage Tsst ( Water ImmersionTest)

The wire shall withstand without breakdownan ac voltage of 3 kV at a frequency of 50 Hzapplied for a period of one minute at room tern.perature. The test shall be done after immer-sion of wire in water for a minimum period of12 hours.

5 PACKING

5.1 The winding wires shall either be wound onspools/reels conforming to IS 482 ; 1981, orsupplied in coils packed and labelled.
