THREADED BASE, GROOVED BASE for distribution devices and electrical equipment

详情

BASE - THREADED BASE 

It is mainly used for insulation and support of live parts in public frequency AC voltage *5 kV and substations, distribution substations, distribution devices and electrical equipment. 

BASE - GROOVED BASE 

It is used for insulating and fixing conductors in high voltage overhead transmission and distribution lines. Generally, insulator strings are assembled for different voltage levels of lines.
