InGround Superlight

Applied in harsh environments with potential mechanical impact: in grounds of all the groups, bogs, unnavigable rivers.

Applied in ducts, trays, blocks, tunnels, and collecting channels.

Also applied for aerial installation between buildings and supports. However, one should consider its bigger weight comparing to self-supporting cables.
