APPLICATIONS

TECHNOKONTROL IB-YSL(St)Y-P are multipair overall shielded cables, intended for intrinsically safe circuits and explosive conditions zones, designed for operating voltage 300/500 V.

Paired structure decreases mutual influence between signals transmitted along the cable.

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

The cables are designed to offer high flexibility combined with tensile strength.

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 PN-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.

The cables are suitable for fixed indoor and outdoor installations.

CONSTRUCTION

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

- PVC insulation, identification of pairs:

    ”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 laid-up in layers,

- cable core wrapped in polyester tape,

- overall electrostatic shield incorporating aluminium-polyester tape and stranded annealed tinned copper drain wire (class 2),

- oil, petrol and UV radiation resistant and self-extinguishing (oxygen index bigger than 29%) PVC cable sheath, blue RAL 5015 according to VDE 0165 6.1.3.2.3.
