APPLICATIONS
YStYekw 300/500 V and YStYekwżo 300/500 V are cables designed for wet or dry locations and intended for control, protection and monitoring systems or power supply, all in power engineering. The cables are also intended for wiring industrial plants, such as production lines, air-conditioning equipment etc.
Cable inner sheath offers enhanced protection against mechanical damage.
The overall shield protects the cables against external electromagnetic interferences and prevents emission of interferences produced in the cables.
The cables are suitable for indoor installations connecting fixed and movable equipment.
Cable outer sheath is oil-resistant.
CONSTRUCTION
- flexible, multiwire conductors, stranded of bare annealed copper wires (tin-plated on request), meeting requirements of class 5 per PN-EN 60228,
- black PVC insulation and white conductor numbers printed on it for identification,
- insulated conductors laid-up in layers, green-yellow protective conductor located in the outer layer in YStYekwżo 300/500 V cable,
- inner PVC sheath,
- tinned copper wire braid shield of effective density coverage,
- PVC cable sheath, grey RAL 7001, other colours also available.
AVAILABLE UPON REQUEST
YStYekw-O 300/500 V and YStYekwżo-O 300/500 V - cables designed for frequent contact with petroleum products, as in petrol stations and stores, where engine fuels and lubricants are pumped or handled. The cable sheath is then made of special PVC compound meeting oil resistance requirements of Polish standard PN‑EN 60811-404.
YnStYekw 300/500 V and YnStYekwżo 300/500 V - cables of reduced combustibility, sheathed with special self-extinguishing PVC of high oxygen index and pass combustibility test according to PN-EN 60332-3 standard.
