APPLICATIONS

RE-2Y(St)Yv-fl are multipair, overall shielded cables intended for control and instrumentation circuits, for signal, monitoring and data processing systems and for analogue or digital data transmission, all in industrial electronics applications.

Sheathing PVC of high oxygen index is UV radiation and weather resistant, is self-extinguishing and flame retardant. The cables pass combustibility test according to EN 60332-3 standard.

The cables are oil-resistant and designed for frequent contact with petroleum products, as in petrol stations and stores, where engine fuels and lubricants are pumped or handled.

High digital data transmission performance is achieved by polyethylene insulation and small capacitance of cable circuits.

The cables are protected by an overall electrostatic shield against external electric interferences.

The cables are suitable for indoor and outdoor installations in dry and wet locations, also for direct earth burial.

CONSTRUCTION

- flexible, multiwire conductors, stranded of bare annealed copper wires (tin-plated on request), meeting requirements of class 2 per PN-EN 60228,

- polyethylene (PE) insulation - identification colour code:

    ”a” wire – black insulation and white pair number printed on it,

    ”b” wire – white insulation and black pair number printed on it,

- insulated conductors twisted into pairs,

- pairs and an orange communication conductor laid-up into a cable core,

- cable core wrapped in polyester tape,

- overall electrostatic shield incorporating aluminium-polyester tape and stranded annealed tinned copper drain wire,

- enhanced, oil, petrol and UV radiation resistant and self-extinguishing (oxygen index bigger than 29%) PVC cable sheath, black RAL 9005 or blue RAL 5015 (for intrinsically safe circuits).
