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/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;
*5 – suited for cables of up to *5 kN total load. The cable-to-clamp sealing withstands loads up to 7.5 kN;
Dmin/Dmax – minimum/maximum optical cable diameter, mm;
P – equipped with a protective device.

It is possible to manufacture helical clamps upon the client’s request!
