Product 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;

NSO***-Dmin/DmaxP helical dead-end clamps

Helical dead-end clamps of NSO***-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.

A helical dead-end clamp is a U-shaped strand of several helical wires joined together via a special solution and covered with an abradant on the inside.

The protective device is a set of stranded helices joined together via a special solution and covered with an abradant on the inside.

The NSO***-Dmin/DmaxP set includes:

•  

  a thimble (if provided for a complete set);

•  

  a power helix Lc= ********0 mm consisting of adhered helices covered with an abradant

•  

  a protective device Lc= ********0 mm (the number of strands depends on the cable diameter).
