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.
