InGround Standart Reinforced Dielectric

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.

Double armor makes the cable suitable for harsh environment applications: in cryosolic grounds, on the bottom of navigable rivers and basins.

Perfect protection from rodents, suitable for duct installation.

Allowable tensile strength up to 40 kN/cm.

Resistance to crushing loads from 1kN/cm.

All-dielectric construction.

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

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

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