Cable KSPV: description, purpose, technical characteristics of the product

The KSPV cable is a signal wire used for a fixed internal installation when alarm systems, communications and messages are connected in networks. It is indispensable for the installation of fire and burglar alarms, data processing systems. It should be noted that the cable KSPV is one of the budget options for the organization of network connections. It is used not only indoors, but also outdoors. However, it is forbidden to run the wire in places that are not protected from direct sunlight.

How is the KSPV conductor organized?

Cable KSPV is a stranded wire. It consists of single-wire copper cores, each of which is a separate insulating shell made of a polyethylene composition. As determined by the CSCA-certificate, these cables consist of conductors with diameters of 0.4, 0.5, 0.64, 0.8 mm. The number of cores can vary from 2 to 20. In this product, PVC-plastic is used as the upper insulating material . The cable is always white.

terms of Use

The operating temperature range, allowing the laying and installation of the cable, is from -10 to +50 degrees Celsius; Operation of the product - in the range from -40 to +60 degrees. The tensile load on the cable should not exceed 50 N / mm ² from the total cross-section of the conductors, which conduct electric current. The radius of bending allows a seven-fold value of the minimum outer diameter of the cable. The service life of the product is not less than 12 years.

Technical characteristics of KSPV-cable

For a wire of this length of one kilometer at a temperature regime of about 20 degrees Celsius, the resistance will not exceed 148 ohms / km. In this case, the resistance of the insulating material of the conductor under the same conditions, as well as the average humidity, will be about 6500 MΩ. Cable KSPV is able to withstand the voltage of electric current within 250V. The wire is very flexible, it can withstand up to 15 bends provided that their angle is not more than 90 degrees. However, the radius of the folding of the cable can exceed the nominal section of the wire by an order of magnitude . This conductor is quite resistant to changes in temperature and air humidity: the amplitude of the temperature regime acceptable for its operation can fluctuate in the range -40 ... +60 ⁰ C. For normal operation of the KPSV conductor , the air humidity should not exceed 98% at The temperature of the medium is 35 degrees Celsius above zero. If this mode of operation is observed, the service life of the cable will be at least 15 years.

Conclusion

Signal cables are a rather popular product, without them you can not build an effective system. Such products are used in various fields of activity, especially where fire or burglar alarm is required. The technical characteristics of cable products have a direct impact on the efficiency of the entire security system. Thus, the use of a poor-quality wire can lead to a high frequency of false positives. The special structure of the KPSV-cable allows to withstand with high efficiency all sorts of interference, thereby eliminating the frequent occurrence of erroneous alarms.
