Description

MetalProm clamps markings

The dead-end optical cable clamp marking NSO-MDRNk-Dkmin/DkmaxP or PSO-MDRNk- Dkmin/DkmaxP consists of several symbolic (alphanumeric) groups:

• the first three symbols (the letters NSO) stand for helical dead-end clamp; the abbreviation PSO stands for supporting helical clamp;

• the next symbolic group (MDRNk) stands for maximum allowable cable tension load;

• the symbols Dkmin/Dkmax designate the cable (pipeline) diameter range in mm;

• the symbol P (if indicated) designates the presence of a protective device;
  
   

  PSO**-Dmin/Dmax supporting helical clamps

  Helical clamps of PSO**-Dmin/Dmax type are used for mounting self-supporting optical cables on lighting poles, overhead line supports, overhead catenary posts at railways, on buildings and other structures.

  The maximum cable line rotation angle is *0 degrees.

   

  The PSO**-Dmin/DmaxP set includes:

• a suspension helix consisting of helices adhered together and covered with an abradant. The helix has a ring shape;

•
