Foreword

GB/T 9326 "AC 500kV, paper or polypropylene paper laminate insulated metal sheathed cables and accessories" consists of five parts.

--- Part 1. Test;

--- Part 2. AC 500kV and below paper insulated lead sheathed cables;

--- Part 3. Terminal;

--- Part 4. Connector;

--- Part 5. Pressure tanks. This part of GB/T 59326 Part of.

This Part replaces GB 9326.5-1988 "AC 330kV and below-contained oil-filled paper - insulated cables and accessories for pressure tank". This section technical differences compared with GB 9326.5-1988 is.

--- Increase Normative references (see Chapter 2);

--- According to GB/T 9326.1-2008 content adjustment and modification of the "technical requirements" and "pilot project and requirements," the relevant content;

--- Increase in stainless steel as the main material (see 4.1);

--- Increasing the pressure tank size (see Table 1);

--- Expanding the range of hydraulic pressure tank and the corresponding test requirements (see Chapter 7).
