Relief Cable

relief cable

Features

  • Characteristic: light weight, tensility resistance, crush resistance , strong specific gravity high, easy bend,oil resistance, abrasion resistance flexibility. So it can installation, maintenance and manage easily.
  • Aramid yarn provide mechanical strength with cable
  • Cable diameter and bending radius small, It can installation freely in narrow room
