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/DmaxP supporting helical clamps

Helical clamps of PSO***-Dmin/DmaxP 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 ring thimble;

a suspension helix consisting of helices adhered together and covered with an abradant. The helix has a ring shape. L=******0 mm;

a protective device, L=********0 mm.

The PSO***-Dmin/DmaxP clamp marking

PSO supporting helical clamp;
*2 suited for cables of up to *2 kN total load. The cable-to-clamp sealing withstands loads up to 6 kN;
Dmin/Dmax minimum/maximum optical cable diameter, mm;
P equipped with a protective device.

It is possible to manufacture helical clamps upon the clients request!
