.

SKU: P 2180 M x L
Categories: ,

Intended use: achievement of permanent spherical fixed points for the mounting of phase clamps for short-circuiting devices in high/medium voltage power substations.

Application: manual, performed on flat bars, packets of bus bars of various thicknesses, with the de-energisation of the installation.

Types of spherical parts – 3 types (with various forms: straight or inclined):
-Sphere Ø30 mm
-Sphere Ø25 mm
-Sphere Ø20 mm

Components:

  • Spherical coupling part -1 piece
  • Fittings – 1 set (with sizes as per the customer’s demands)

Tips: these spherical pieces (Ball studs) must replace bar assembly screws.
