GB/T 12706.4-2008 Power cables with extruded insulation and their accessories for rated voltages from lkV (Um=1.2kV) up to 35kV (Um=40.5kV) - Part 4: Test requirements on accessories for cables with r (English Version)
Power cables with extruded insulation and their accessories for rated voltages from lkV (Um=1.2kV) up to 35kV (Um=40.5kV) - Part 4: Test requirements on accessories for cables with r
1 Scope
This part of GB/T 12706 specifies the test requirements for type testing of accessories for power cables with extruded insulation with rated voltages from 3.6/6 (7.2)kV up to 26/35 (40.5)kV, complying with GB/T 12706.2-2008 or GB/T 12706.3-2008.
Accessories for special applications, such as aerial cables, submarine or ship cables or hazardous situations (explosive environments, fire resistant cables or seismic conditions), are not included in this part.
Formerly, approvals of products now covered by this part have been achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performance. The publication of this part does not invalidate existing approvals. However, products approved according to these earlier standards or specifications cannot claim approval to this IEC standard unless specifically tested to it.
It is not necessary to repeat these tests, once successfully completed, unless changes are made in the materials, design or manufacturing process which might affect the performance characteristics.
Test methods are included in GB/T 18889-2002.
