GB/T 5964-2008Coaxial cable connectors used in nuclear instrumentation (English PDF)

Foreword

This corresponds to the standard IEC 60498. 1975 "Nuclear instrumentation with high pressure coaxial connectors" and IEC 60313:2002 "Nuclear Laboratory instruments for Coaxial cable connector ", and IEC 60498. 1975 and IEC 60313:2002 non-equivalent.

This standard replaces GB/T 5964-1986 "nuclear instrumentation with high pressure coaxial connectors." this standard and GB/T 5964-1986 The main differences are as follows.

--- Standard name changed to "coax connectors used in nuclear instrumentation";

--- Increase IEC 60729 and other normative references;

--- Increase the "Terms and Definitions", such as "peak voltage", "safe high-voltage connector (SHV)" and other terms;

--- Increase in Appendix A "signal transmitted by a coaxial cable connector", whose contents are IEC 60313 recommended three coaxial signal transmission Cable connectors.

Appendix A of this standard is a normative appendix.

The standard proposed by China National Nuclear Corporation.

This standard by the National Standardization Technical Committee on nuclear instrumentation.

This standard was drafted. nuclear (Beijing) Nuclear Instrument Factory, Institute of Nuclear Industry Standardization.

1 Scope

This standard specifies the high-voltage coaxial connector mating portion of the structure and size of the two types and the main electrical properties.

This standard applies to high-voltage coaxial connectors and nuclear electronic instrument connected.

According to the structure and size and technical requirements of this standard manufactured products with similar foreign products in the mechanical and electrical properties can be achieved complete exchange. About signal transmission coaxial connectors, see Appendix A recommended three signal connector.
