Cable construction
  • Electrolytic copper tinned, very finely stranded conductor to DIN VDE 0295
  • Newly developed special compound based on high quality EPR (at least 3GI3) improved mechanical and electrical characteristics
  • Core arrangement laid up with length of lay 7 x Ø, three-core design, protective earth conductor split into 3 in the outer filter PROTOFIRM Special: First Sheath
  • Newly developed special compound based on EPR, quality at least 5GM3, also serving as water barrier; colour: red
  • Reinforced braid made of polyester threads in a vulcanized bond between the sheaths. Resulting in a high strength of the sheath system. PROTOFIRM: 2nd and 3rd sheath
  • A sheath system with a unique combination of flexibility and robustness has been achieved through the use of a new structure. Abrasion and tear proof special rubber compound
  • Colour: bright red/red
  • Weather resistant, unrestricted use on outdoors and indoors, resistant to ozone, UV and moisture
