GB/T 17557-2010Insulating materials for shipboard and offshore units, power, control, instrumentation, telecommunication and data cables (English PDF)

Foreword

This standard is identical with IEC 60092-351:2004 "marine electrical equipment Part 351. ships, offshore units power, control, Instrumentation, data communications and cable insulation material "(English version).

This standard is equivalent translation IEC 60092-351:2004. For ease of use, this standard made the following editorial changes.

"." A) with a decimal point instead of IEC 60092-351:2004 as a decimal point, "";

b) Remove the IEC 60092-351:2004 Foreword;

c) "IEC 60092 this part" to "this standard";

d) For IEC 60092-351:2004 international standard references, there is tantamount to the adoption of a standard as part of this country with reference Standard instead of an international standard, and the rest is not tantamount to the adoption of the standard, in the standard are a direct reference.

e) IEC 60092-351:2004 Normative documents in IEC 60811-1-2:1995 Year of error, to IEC 60811-1-2. 1985;

f) The latest version of the legend undated reference standard footnote "1)", "2)" description;

g) For ease of viewing, increased the number in Tables 3 and 4;

h) IEC 60092-351:2004 Table 3 "have the copper conductors aging" in the upper right corner missing footnote "a", to supplement this standard;

i) Fact Sheet 4 for both high temperature pressure test load time footnote "3)", "4)" will be described.

This standard replaces GB/T 17557-1998 "marine power cable insulation material." this standard 17557-1998 major changes compared to GB/T as follows.

a) a thermoplastic material, code-named "PVC/A" to "PVC".

b) elastomeric or thermosetting material increased 6 kinds. HEPR, HFEPR, HFHEPR, HFXLPE, HFS95, HF90.

c) the maximum normal operating temperature of the conductor allowable changes. from 60 °C rose to 70 °C, EPR and XLPE by a PVC 85 °C raised to 90 °C.

d) establishes the maximum temperature at S95 short circuit conductor allowed.

e) air box divided into non-aging aging conductor and copper conductor aging categories, mechanical performance requirements of the original air box included first after aging Class requirements.

f) Special Features.

--- PVC when the high temperature pressure test, in both cases the load time from the "outside diameter of the sample d<=12.5mm", "outer diameter of the sample d > 12.5mm "were replaced by" The first one kind of situation "and" the second state of affairs "and annotation;

--- The thermal expansion test, XLPE maximum permanent elongation rate of 25% reduction of 15%, S95 of the test temperature (200 ±

3) °C was raised to (250 ± 3) °C;

Deviation --- resistance to cracking in the test temperature is increased to ± 2 °C ± 3 °C;

--- Low temperature performance of the test temperature deviation increase requirements ± 2 °C;

--- Increased acidity, hardness and modulus of elasticity of demand.

g) added three appendices.

The Standard Annexes A and B are normative appendix Appendix C is informative appendix.

The standard proposed by China Shipbuilding Industry Corporation.

This standard by the National Standardization Technical Committee Marine Boats (SAC/TC12) centralized.

This standard was drafted. China Shipbuilding Industry Corporation seventh THOUSAND AND FORTY Institute, Jiangsu Ocean Dongze Cable Group Co., Ltd., Changzhou Eight benefits of cable Limited.

1 Scope

This standard specifies the electrical ships, fixed and mobile offshore units power, control, instrumentation, data communications and cable insulation materials Properties, mechanical properties and special performance requirements.
