Reliable tension anchor clamps
Nowadays, the most widely used technology for fastening overhead cables is fastening cables with clamps (tension and support). This technology involves the use of special clamps that are attached to the reinforcement installed on the supports or facades of houses.Tension clamps are used in places of high stress or at multiple points in the middle of a long straight section. Their task is to rigidly fasten the cable to the supports.
For self-supporting optical cables, anchor clamps are usually used as tension clamps. The body of such a clamp is made of high-strength plastic or aluminum alloy, and wedge-shaped inserts with teeth move freely in the grooves. The principle of operation of the anchor clamp is based on the self-tightening of the cable by the movable wedges of the clamp.
Universal anchor clamps
In addition to clamps using wedge inserts with teeth, anchor clamps with a slightly different principle of gripping a cable or cable can be used. The fact is that if the cable is installed incorrectly, in conditions of extreme stretching or in case of accidental sharp loads (falling branches, gusts of wind, etc.), the teeth of the clamp can partially shift the sheath of the cable, exposing it. In the future, this can lead to corrosion of the cable and deterioration of the reliability of the line.Recently, anchoring clamps without teeth have become increasingly popular among our customers.
The correct choice of fastening elements
Support clamps are intended for fixing wiring to intermediate-angle and intermediate supports of transmission lines. With tension clamps, the wires are fixed to the tension strings of the anchor supports of high-voltage lines. Steel hooks are used to fix overhead transmission lines, pin insulators and telegraph lines to poles. They are screwed into the support racks. Fastening of insulators is carried out on hooks using special caps or tow. In some cases, hooks are welded to the crossheads of the supports.The correct choice of fastening elements in the design of power transmission lines will ensure its long and reliable operation. Among the main points that you need to pay attention to, it is worth noting the technical characteristics of the cable used. It is on them that the parameters of the fasteners will largely depend. The diameter of the cable or its supporting element.
Optical cable used in the field of telecommunications
Optical cable today is widely used in the field of telecommunications. Optical in comparison with copper has many advantages, but its use is complicated by many problems, the main of which is the method of cable laying. The most widespread currently is the hanging method. Laying a fiber-optic cable over the air is the simplest method of organizing transmission communications. An important role in laying communication lines is played by the fastening of an optical cable. It is manufactured according to wiring diagrams to avoid the risk of fiber damage. Much attention is paid to the accuracy and accuracy of installation. When fastening, the cable must not be stretched, bent, struck; during installation, it must not be subjected to tension and sagging, or to low temperatures.

On our website you can purchase not only various cables, but also clamps for them. People cannot do without this kind of technical product when laying communication lines: the wires through which the energy they need flows must be fixed on a variety of objects and surfaces.When choosing clamps, it is necessary to clearly know which hooks they will be hung on in order to avoid a situation when the hole diameter in the clamp is less than the hook diameter.
