Roll springs for constant pressure

type : ППД

  • Designed to attach the earth wires to the metal sheath and covers from armored bands and also for installation of metal screen in cable joints without use of soldering technology
  • Indispensable for installation of not brazed earthing nodes in HS kits, for cables with XLPE and PVC insulation
  • Made of high quality stainless steel AISI 301 with a high content of chromium and nickel
  • The combination of corrosion resistance and elastic strength properties of “KBT” springs ensures a uniform clamping force under all conditions of operation
  • Each spring covers a wide range of cable sizes
  • Seven “KBT” springs cover the range from 7 to 110 mm and allow the installation on almost all known types and sizes of modern cables
  • Constant radial pressure after installation
  • The longitudinal edges of “KBT” springs are smoothed, not sharp. There are no cutting burrs, which eliminates injuries and cuts during installation
  • The rounded end of the spring is bent for easy grip and installation
  • For identification, each spring has size marking
  • In contrast to soldering, mounting using ППД, does not require special knowledge and skills that greatly reduces the risk of problems associated with “human factor”
  • Easy reliable and quick installation without using special tools
