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 for trunk optical fiber communication lines

Helical clamps of PSO***-Dmin/DmaxP type are used for mounting self-supporting optical cables to high voltage power lines.

The maximum cable line rotation angle is *5 degrees.

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

• equipped with “lodochka” triangular thimble;

• the power installation consists of 2 assemblies. The helices in these assemblies are joined together via an adhesive and are covered with the L=********0 mm abradant.

• a protective device, L=********0.

The PSO***-Dmin/DmaxP clamp marking

PSO – supporting helical clamp;
*0 – suited for cables of up to *0 kN total load. The cable-to-clamp sealing withstands loads up to *9 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!
