Outer Jacket Blue, Intrinsic Safety, Flexible, EMI Preferred Type
https://www.hitechcontrols.com/cables/control_cable/intrinsic_safe/oz_bl_cy.html

Application:

For hazardous areas the cables with special marking (blue) (hazard type-i-) used as flexible control and measuring cables to meet the requirements for the installation of electrical apparatus. These installations are not grounded and require a separate power circuit. Those cables are not suitable for underground laying.
The copper braided shielding ensures the transmission of data signals and free from interference.
EMI = Electromagnetic Interference
To optimize the EMI features we recommend a large round contact of the copper braiding on both ends.
CE= The product is conformed with the EC Low-Voltage Directive 73/23/EEC and 93/68/EEC
