Coupling system with spherical pieces

.

SKU: P 2180 M x L
Categories: ,

Intended use: execution of permanent spherical fixed points for the mounting of phase clamps for short-circuiting devices in high / medium voltage power stations, on conductors / bars with rectangular cross-section, in order to improve the mounting conditions of short-circuiting devices.

Mounting: manual, during overhaul works with the de-energisation of the installation. The application is performed on flat bars, bar packets of busbars of various thicknesses, using appropriate tools that allow the firm tightening of the part on the conductor.

Types of spherical parts: 3 types (with various forms: straight or inclined):

-Fixed parts type ‘’Sphere Ø30 mm”

-Fixed parts type ‘’Sphere Ø25 mm”

-Fixed parts type ‘’Sphere Ø20 mm”

Components:

-Spherical coupling part -1 piece

-Assembly item – 1 set (with sizes as per the customer’s demands)

Tips: these fixed spherical parts are recommended for installation instead of bar assembly screws.
