OKBs

Application

OKB-s is designed for installation into grounds of 1-5 groups (depends on cable construction), cable ducts, tunnels in case of high requirements of crush strength.
OKBs cable with flame retardant protective jacket is designed for installation according to exclusive standards of fire safety.
OKBs cables in fireproof design FRHFLTx are used for laying in fire protection systems, as well as in other systems that must remain operational in a fire.

longitudinal watertightness of the cable is provided by a hydrophobic gel
