ACCESSORIES - ELECTRICAL INSULATORS

General description

ELECTRICAL INSULATORS

Functions

  • Electrical insulators for distribution bars are used in the installation of various safety sockets, manifolds, distribution and control panels, other electrical installations used indoors, up to the permissible voltage limit.
  • Compared to traditional ceramic insulators, they offer space and weight savings.
  • The inserts with internal thread necessary to fix the supports are incorporated in plastic in the casting phase.
  • Insulating supports represent advantageous mechanical, thermal and electrical properties, they can be installed quickly and safely.
  • The breakthrough voltage can be increased by several overlapping supports.
