ZSNP Shear off screw connector up to 1 kV

ZSNP Shear off screw connector up to 1 kV

ADVANTAGES OF SCREW TECHNOLOGY:

  • possibility of using one connector for conductors of various conductor structures and a wide range of cross-sections
  • savings in the field of keeping stocks (it is enough to order e.g. 2 types of connectors to stock instead of e.g. 10)
  • versatility
  • assembly speed
  • wide range of cross-sections (they are covered with one connecting element)
  • simple and quick assembly (performed with small and light tools)

Product innovation:

  • repeatability of the bolt break point always (regardless of the type and dimensions of the core) flush with the outer surface of the connector body
  • connectors for copper and aluminum conductors, class 1, 2 and 5 in the entire size range from 10 to 1000 mm2
  • guarantee of no damage to cable cores during the assembly process
  • higher resistance to relaxation of clamping forces
  • limitation of partial discharges in connectors
  • universality of the system consisting in a significant reduction in the number of sets of coupler-clamping units compared to traditional solutions
  • system of cable connections repeatable in terms of the required pressure force
  • reduction of frictional forces when assembling the connection system on the cable core = no damage to the cable cores when installing the connector
  • possibility of joining class 5 flexible conductors, for which there is currently no screw fittings for connecting them
