Indian Standard SPECIFICATION FOR
DRUMS FOR ELECTRIC CABLES
0. FOREWORD
0.1 This Indian Standard was adopted by the Indian Standards Institu- tion on 30 December 1982, after the draft finalized by the Power Cables Sectional Committee had been approved by the Electrotechnical Division Council. 0.2 The drums on which electric cables are wound play an important role during transport and storage of cables and as &cb need has been felt to prepare a specification for rationalizing their sizes being used currently. 6.3 In this standard, drum size is indicated by a four digit number, the first two digits indicating the diameter of disc in dm and the last two digits indicating the diameter of barrel in dm ( if necessary, value of dia- meter rounded to next number is taken in order to get four digit number ) ( see also 8.1.1 ). 0.4 Recommendations for choosing drums having appropriate barrel diameter for different types of cables are given in Appendix A for the guidance of users. The clearance between the outermost layer of the caLle and the edge of the flange should be at least 75 mm or equal to the dia- meter of the cable whichever is less. 0.5 This standard recognizes the use of mild steel or cast iron for bushes or centre plates used for drums. However, details of cast iron bushes are under consideration, 0.6 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expres- sing the result of a test, shall be rounded off in accordance with IS : Z- 1960;. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
1. SCOPE
SECTION 1 GENERAL
1.1 This standard covers requirements for wooden drums for electric cables.
*Rules for rounding off numerical values ( rrvirrd ).
