Scope

This Part of GB/T 12706 specifies the type test and test requirements of the
accessories for extruded insulation power cables with rated voltages from 3.6/6 kV
(7.2kV) up to 26/35 kV (40.5kV), complying with GB/T 12706.2-2008 or GB/T 12706.3-
2008.
This Part excludes the accessories used under special conditions, such as aerial
cables, submarine or ship cables or hazardous situations (explosive environments, fire
resistant cables or seismic conditions).
Formerly, approvals on products covered by this Part have been achieved on the basis
of obtaining the national standards and/or the demonstration of satisfactory service
performance. This Part does not invalidate existing approvals. However, products
approved according to those former standards or specifications cannot claim approval
to this Part unless specifically tested to it.
It is not necessary to repeat these tests, once pass the tests, unless changes are made
in the materials, design or manufacturing process which might affect the service
performance characteristics...
Test methods are included in GB/T 18889-2002.
