JG/T 313-2014Metal sheath inorganic mineral insulated cables and their terminations with a rated voltage not exceeding 0. 6/1 kV (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces JG/T 313-2011 "rated voltage 750V and below metal sheath inorganic mineral insulated cables and terminals." this standard compared with JG/T 313-2011, in addition to editorial changes outside the main technical changes are as follows.

--- The rated voltage of 750V and below to the rated voltage 0.6/1kV and below, and modify the finished cable test voltage value (see 6.4, 2011 Edition 5.5).

--- Modify the normative references (see Chapter 2, 2011 edition Chapter 2);

--- Modify the burning time in the fire test (see 6.4.4, 2011 version 5.5.5);

--- Modify the insulation thickness measurement of the content (see 6.2.2.1.2.2.2.2011 edition 6.3.1);

--- Increased insulation resistance type test requirements (see Table 11, No. 2);

--- Modify the test category in the inspection category (see Table 11);

--- Added cable terminal diagram in Appendix C, canceled the cable structure and through the connector diagram.

This standard reference IEC 60702-1.:2002 "rated voltage 750V and below mineral insulated cables and terminals Part 1. Cable" (British Edition), IEC 60702-2.:2002 "Mineral insulated cables of 750 V and below rated voltage and terminating part 2. Terminals" (English version), and IEC 60702-1.:2002, IEC 60702-2.:2002, the degree of consistency is not equivalent.
