InGround Standard

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.

All cables of this group can be produced in versions H and (A)-HF.

H — cable jacket is made of a polymer material not propagating fire in a single laying.

нг(A)-HF — cable jacket is made of a polymer material, flame retardant in a group laying, with low smoke emission, halogen-free.
