GB/T 9326.4-2008Oil-filled, paper or polypropylene paper laminate insulated, metal-sheathed cables and accessories for alternating voltages up to and including 500kV - Part 4: Joint (English PDF)

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 49326 Part of.

This Part replaces GB 9326.4-1988 "AC 330kV and below-contained oil-filled paper - insulated cables and accessories for fittings." This section technical differences compared with GB 9326.4-1988 is.

--- This part of GB/T 9326.1 corresponds to the voltage applied to scale up 500kV, and includes polypropylene composite paper insulation;

--- GB 9326.4-1988 modify the definition of straight joints, which extended through connector and insulation joints (see 3.1 and 3.2);

--- Modify the model designation (see Table 1);

--- Since the joint but also the use of epoxy resin parts, thus increasing the epoxy preform and epoxy casing technical requirements (see 6.4);

--- Increasing the pressure test as a test method for the selective fittings seal test (see 8.2.2).
