LIGHT NIGHT MARKING APPC-S

Light marking of high-voltage power line wires.

According to the requirements of the IKAO (International Civil Aviation Organization) and the industry standards of PJSC ROSSETI, “Markers for overhead power lines” in the dimensions of overhead lines with a voltage of 35 kV and above must be used on overhead line elements located in the area of the airfield and air routes that rise above the established obstacle restriction surfaces, as well as objects located in traffic zones and maneuvering of aircraft, in the area of small aircraft flights, when crossing roads of category IA, IB, IB, at large crossings, and on the airfield territory.

Krasny Kvadrat LLC has developed and produces wire barrier lights (ZOP) in the dimensions of 110-500 kV overhead lines-APPC-S (autonomous constant glow device), to ensure the safety of aircraft flights, as well as to ensure the integrity of the overhead line and its trouble-free operation.

A special feature of the APPC-S is that the power supply for lighting a neon lamp is supplied directly from the carrier high-voltage wire. The APPC-S system is completely self-contained and does not require additional power sources.

In accordance with the requirements of the IKAO (International Civil Aviation Organization) and industry standards of PJSC Rosseti, APPC-S generates low-intensity light radiation of type A (with a light intensity of 10 cd).

One of the features of the development is a lamp with an increased electrode area and low operating current, which significantly increases the service life of the device.

The APPS-S device is certified for compliance with the technical requirements of PJSC Rosseti (Protocol on extending the validity period of the Conclusion of the Attestation Commission of PJSC Rosseti No. IP-38/21 dated 31.03.2021) and is recommended for use at the facilities of subsidiaries and affiliates of PJSC Rosseti.

Technical parameters of the APPC-S devices are given in the table:

The production of Krasny Kvadrat LLC is located on its own territory, equipped with the latest equipment and is constantly being improved to optimize the full cycle of work. Long-term partnerships have been formed with domestic manufacturers of components and spare parts.
The implementation of APPC-S devices is aimed at maintaining the policy of import substitution of the equipment and materials used in Russia.

At the same time, it should be noted that Krasny Kvadrat LLC is the only manufacturer of light protection and color marking products that has the entire range of ZOP equipment certified for use by Rosseti PJSC.
