GB/T 17755-2010Single-and three-core power cables with extruded solid insulation for rated voltages 6 kV(Um=7.2 kV) up to 30 kV(Um=36 kV) in ships (English PDF)

Foreword

This standard is equivalent to IEC 60092-354.:2003 "Marine electrical equipment Part 354. Rated voltage of 6kV (Um = 7.2kV) to 30kV (Um = 36kV) single-core and multi-core extruded solid insulated power cable. " this standard is equivalent to translation IEC 60092-354.:2003.

For ease of use, this standard has been modified as follows.

a) the word "part of IEC 60092" is replaced by "this standard";

b) Replace the comma as a decimal point with a decimal point "."

c) prerequisites for the removal of international standards;

d) In order to be consistent with the existing national standard series of standards, the standard name to "marine rated voltage of 6kV (Um = 7.2kV) to 30kV (Um = 36kV) single-core and three-core extruded solid insulated power cable ";

e) For international standards cited in IEC 60092-354.:2003, this part of the international standard, which is used as our standard, Standards instead of international standards, the rest is not equivalent to the use of our standards, in the standard are directly quoted;

f) Delete the words "considered by TC18" in Chapters 1 and 4;

g) Replace "(see 11.1)" in Table 1 with the words "(see 11.2)");

h) "85 ° C" in Table 7 was changed to "90 ° C".

This standard replaces GB/T 17755-1999 "rated voltage of 6kV, 10kV and 15kV extruded insulation single and three core marine power cable".

Compared with the original standard, this standard has the following main changes.

a) rated voltage from the original "6kV, 10kV and 15kV" to "6kV, 10kV, 15kV, 20kV and 30kV";

b) the nominal cross-sectional area of the conductor, from the single-core cable maximum cross-sectional area of "630mm2" to "1000mm2";

c) change "270mm" in Chapter 7, "Continuity of Marks" to "275mm";

d) changed the frequency test voltage;

e) the deletion of 17.1 in the original standard.

This standard is proposed by China Shipbuilding Industry Corporation.

This standard is nationalized by the National Marine Ship Standards Technical Committee (SAC/TC12).

The drafting of this standard. China Shipbuilding Industry Corporation, the 107th Institute, Nanyang Cable Group, Shanghai Nanyang Electric Co., Ltd., Changzhou eight benefits Cable Co., Ltd.

1 Scope

This standard applies to the fixed-laying of the extruded solid insulation, conductor and core shield, rated voltage of 3.6/6 (7.2) kV, Ships and Offshore Installations of 6/10 (12) kV, 8.7/15 (17.5) kV, 12/20 (24) kV and 18/30 (36) kV (see Chapter 4) cable. The maximum rated voltage for marine power cables is 8.7/15 (17.5) kV.

See Chapter 8 for the various types of power cables. Unless otherwise specified in this standard, the structural requirements and test methods shall comply with IEC 60092-350 Provisions.

The purpose of this standard is.

- Standardize the following cables. the cable is laid according to IEC 60092-350 and its safety and reliability are Guarantee - standardize production requirements and characteristics for such cables that are directly or indirectly related to safety;

- Specifies the test method to check for compliance with these requirements.

Note 1. Only cables with radial fields are involved.

Note 2. IEC 61892-4, Mobile and stationary offshore installations - Electrical installations - Part 4. Cables.
