KSPV cable is a signal wire used for fixed internal installation when connecting alarm systems, communications and messages in networks. It is indispensable for the installation of fire and burglar alarms, data processing systems. It should be noted that the KSPV cable is one of the budget options for organizing network connections. It is used not only indoors, but also in the open air. However, it is forbidden to lay the mentioned wire in places that are not protected from direct sunlight.
How is the KSPV conductor arranged?
The cable KSPV is a multicore wire. It consists of single-wire copper conductors, each of which consists of a separate insulating sheath of a polyethylene composition. As defined by the KSPV certificate, these cables consist of conductors of the following diameters: 0.4, 0.5, 0.64, 0.8 mm. The number of cores can vary from 2 to 20. In this product, PVC compound is used as the top insulation material . The cable is always available in white.
terms of Use
The working temperature range allowing cable laying and installation is from -10 to +50 degrees Celsius; product operation - in the range from -40 to +60 degrees. The tensile load on the wire KSPV should not exceed 50 N / mm 2 from the total cross section of the conductors that conduct electric current. The bending radius allows a sevenfold value of the minimum outer diameter of the cable. The service life of the product is at least 12 years.
Technical characteristics of KSPV cable
For a core of such a wire one kilometer long with a temperature regime of about 20 degrees Celsius, the resistance will not exceed 148 Ohm / km. In this case, the resistance of the insulating material of the conductor under the same conditions, as well as average humidity, will be about 6500 Mฮฉ. KSPV cable is able to withstand 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 cable folding radius can be an order of magnitude higher than the nominal wire cross section. This conductor is quite resistant to temperature extremes and air humidity: the amplitude of the temperature regime acceptable for its operation can fluctuate in the range of -40 ... +60 0 . For normal operation of the KPSV conductor , the air humidity should not exceed 98% at ambient temperature 35 degrees Celsius above zero. Subject to this mode of operation, the cable service life will be at least 15 years.
Conclusion
Signal cables are a fairly popular product, without them it is not possible to build an effective system. Such products are used in various fields of activity, especially where a fire or security alarm is needed. The technical characteristics of cable products have a direct impact on the performance of the entire security system. So, the use of low-quality wires can lead to a high frequency of false alarms of sensors. The special structure of the KPSV cable allows it to withstand all kinds of interference with high efficiency, which eliminates the frequent occurrence of false alarms.
