Foreword

This standard and the International Telecommunication Union ITU-TK. Recommendation 12 "telecommunication device protection with gas discharge characteristics" (2006) a Consistency is not equivalent and according to the development of communication technology, improve production technology and the actual needs of the discharge tube, and a certain amount of supplementary And improve so that the standard scientific, better operability and practicality. This standard replaces GB/T 9043-1999 "communication device over-voltage protection General technical requirements of gas discharge tubes." This standard and GB/T 9043-1999 main technical differences are as follows. --- The gas discharge tube of nominal DC breakdown voltage division finer categories (see Table 1). --- Increase the breakdown voltage of the low-impact category breakdown voltage of the gas discharge tube (see Table 2). --- Modify the breakdown voltage of the conformity assessment method (see Table 3). --- Increased life test test levels, and increases the test categories (see Table 4). --- Clear capacitive test test voltage (see 6.5). --- Increasing the discharge power voltage range and resistance to flow test recommended program (see Appendix B). Appendix A of this standard is a normative appendix, Appendix B is an informative annex. The standard proposed by the People's Republic of China Ministry of Information Industry.
