PCXE-R, PCXHE-R
APPLICATION
Cables substitute: PCEY, PCEHY
Twisted UTP and STP cables for computer networks with lower inflammability and higher resistance to fire propagation according to IEC 60332-3-22, non-halogen, with low smoke density by burning according to STN IEC 61034-2 and low corrosivity of combustion gases according to STN IEC 60754-2. Cables can be used in environment with fire hazard and can be installed also on flammable base. Cables are designated for LAN networks according to IEEE 802.3 10 Base T and for CAT 4 and CAT 5 according to EIA/TIA-568.
CONSTRUCTION
Pic. 1
1 Copper core out of solid wire with diameter of 0,5 or 0,6 mm.
2 Non-halogen conductor insulation out of cross-linked PE. Conductors are twisted into pairs.
3 Screening Al-PET foil with drained CuSn wires (only for type PCXHE-R).
4 Non-halogen flame retardant jacket.

PACKING, DELIVERING, STORAGE, TRANSPORT
All cable types are supplied according to relevant company standards, twisted into coils, eventually greater lengths on wooden or metal drums. Every length is marked with tag with these data:
- producer´s mark
- cable identification
- cable length in meters
- production date
- stamp of quality control
The whole cable can be marked with description on a jacket on request of a client.
Cables can be stored in general in open-air area or in warehouses. They cannot be exposed to thermal radiation and they cannot be stored together with flammable liquids or solvents or with products containing them. It is safe to manipulate with cables at temperature range -10 °C to +50 °C.
It is necessary to assure that cables are not damaged by mechanical or other effects.
