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.
Figure 8
Applied for aerial installations: on power lines, lamp posts, between buildings and constructions. Suitable for aerial installation on transmission equipment and power facilities in dielectric package.
Aerial
Applied for aerial installation on distribution and high voltage power lines, as well as railway catenary.
Indoor
Applied inside buildings (including vertical runs), in trays, channels, on outer sides of buildings, as well as in duct, in tubes and blocks. Suitable for blowing-in into protecting polyethylene tubes.
Drop
Applied for aerial installation on transmission towers, lamp posts, between buildings and constructions.
OPGW/Ground Wire
Applied in the construction of fiber-optic link on overhead transmission lines of 35 kV and more.
Fire Rated
Used for stationary installation when the optical fiber needs extra protection from mechanical damages.
Specialty Cable
For fiber optic monitoring systems.

Transneft officially commissioned the Zapolyarye — Purpe and Kuyumba — Tayshet oil trunk pipelines.
Russian President Vladimir Putin took part in the inauguration ceremony via a teleconference.
The projects delivered the aim of linking new fields in the Yamal-Nenets Autonomous District and Krasnoyarsk Region with resource potential standing at 2 billion tons of crude to the system of oil trunk pipelines of the Russian Federation, ensuring oil transportation to Russian refineries, increasing the potential of export deliveries as well as diversification of Russian crude supply routes in the direction of Asia Pacific markets.
The Zapolyarye — Purpe and Kuyumba — Tayshet oil pipelines are unique projects, with newest construction technologies and methods used in their erection. Communication systems for the pipelines were built with the use of Incab optical cable.
The oil pipelines were built in an extremely challenging natural and climatic environment. More than 50% of the territory where the oil pipelines are laid is described as perennially frozen ground, with 70% of the terrain being swamped and waterlogged. The construction was further complicated by significant temperature drops and the lack of roads as well industrial or other infrastructure.
In the process of building oil trunk pipelines all industrial and environmental safety requirements were met.
