SRPS HD 633 S1:2010

Tests on oil-filled (fluid filled), paper- or polypropylene paper laminate-insulated, metal-sheathed cables and accessories for alternating voltages up to and including 400 kV (Um = 420 kV)

Scope

HD 633 applies to tests on radial field, oil-filled (fluid-filled), paper or polypropylene paper laminate (PPL) insulated metal-sheathed cables and their accessories, which operate with a minimum static pressure of between 20 kPa (0,2 bar) and 300 kPa (3,0 bar) inclusive, a maximum static pressure of not more than 800 kPa (8,0 bar) and a minimum transient pressure of not less than 20 kPa (0,2 bar). (The quoted pressures are above atmospheric pressure.)
NOTE 1: The term 'oil-filled' is under consideration as it does not adequately reflect the nature of the impregnants used in modern cables.
NOTE 2: The cables in this HD are specifically excluded from the scope of the proposed
Pressure Equipment Directive.
HD 633 is applicable also to cables and accessories with maximum static pressures exceeding 800 kPa (8,0 bar). except that sub-clauses 3.2, 4.5 and 5.2 may be appropriately modified by agreement between the purchaser and the manuf acturer.
The tests are applicable to cables and accessories intended to be used in systems with nominal voltages not exceeding 400 kV between phases.
This Part (Part 1) specifies the general test methods applicable to these cables, unless other wise specified in the particular sections of Part 3 of this HD. However, the summary of tests as listed in one only of the particular sections in Part 3 of this HD is mandatory for the particular cable ordered.
Part 2 specifies additional test methods applicable only to certain particular sections of Part 3 of this HD.
Part 3 specifies the lists of tests applicable to the particular cable type.
For cables manufactured in long lengths, the application of this HD is subject to agreement between the purchaser and the manufacturer.
