Blowing
Applied in tubes, ducts, trays, blocks, tunnels, collecting channels, with no risk of rodent attacks. Also applied for aerial installation between supports and buildings on external strength members or using the winding method.
Ducting
Applied in ducts, trays, blocks, tunnels, collecting channels, with a risk of rodent attacks.
Direct Buried
Applied in harsh environments with potential mechanical impact: in all ground types, swamps and harsh rivers.
Submarine
Applied in sea areas (coastal shelf and deep-sea), on navigable rivers, in lakes and water storage basins, in harsh environments, in bogs and unnavigable rivers.

The 20th All-Russian Scientific and Technical Conference took part in Gelendzhik (Russia) in the beginning of June. The subject of the conference was “Increasing Reliability, Efficiency and Safety of Power Engineering”. The event was attended by the representatives of power supply companies, design bureaus and manufacturing enterprises from all over Russia.
Dmitry Gibert, Technical Manager of Incab, and Dmitry Pakhomov, Executive Manager of Global Optics Group of Companies, presented a new product: optical phase conductor (OPC).
The OPC is designed as a central optical tube with loose optical fibers inside it. The free space of the optical tube is filled with water-swellable gel. The central optical tube is covered by several spiral layers of wires. The internal layers are steel aluminium-clad wires. The external layers are made of aluminium alloy. The service life of such cable is at least 50 years.
Application of the OPC in the construction of the optical communication systems provides a reserve communication channel in case of presence of the OPGW and (or) allows to make an independent communication channel, for instance, in case of the conflict of interests of the channel owners. This product is especially useful when it is necessary to replace phase conductors due to their physical wear. In addition, the application of the OPC is possible when the towers are worn and there is no opportunity to increase the load on them. OPC is also helpful when the requirements for the cable sag are very stringent, for example, when the optical communication lines cross navigable rivers or in the mountainous areas, where the vertical drop can be very high.
