SAFETy

Ducab is able to maintain a close watch on world developments in cable technology and regulations and therefore

ensurethatitsproductsaredesignedandconstructedtobehazard-freeundertheprescribedconditionsofuse.

Ducab uses only tried and tested materials and processes in full compliance with all relevant

BritishandInternationalStandards.Ourcablesarethereforemanufacturedforsafeusewithout

risk to health on the understanding that users will exercise the same degree of care in their

selectionandapplication.

Safety is an important issue for Ducab, and the strictest standards are adhered to throughout the

company.Ducab isproudof its safety recordandhasbeenawardedRoSPA (RoyalSociety for the

CONNECTORS

The use of compression type connectors is recommended for XLPE insulated cables since the use of soldered

connectors would limit the maximum short circuit temperature of the cable to 160˚C (and consequently reduce the final

short circuit current by approximately 30%).

OVERHEAD.TERmINATIONS

Ultra violet resistant sleeving or taping should be provided on XLPE insulated cores to avoid degradation due to

exposuretosolarrays.

2. Duetogreatercapacitytowithstandheat,thepermissiblemaximumcontinuousconductoroperatingtemperatureis90˚C and for momentary short circuits the permissible temperature is 250˚C.

3. Higher insulation strength and superior mechanical properties allow lower insulation thickness. The insulationresistancevalueofthecabledoesnotappreciablychangewithconductoroperatingtemperature.

4. XLPE insulation dissipates heat from conductors much faster as its thermal resistivity is 3.5˚C m/W.

5. Heatgenerationintheinsulationitselfislowduetoverylow“lossangle”.

6. Due to the foregoing reasons, an XLPE cable can carry 15% to 30% higher current than a PVC cable with the same conductorsize.

In many situations the conductor size which is ultimately chosen may not be carrying its maximum permissiblecurrent (i.e. its full rated current) and consequently it will not be operating at its maximum designed temperature.Table3�showsthereducedvoltagedrop/ampere/metre/datacorrespondingtoreducedoperatingtemperaturedueto reduced load currents. The first line is applicable to 90˚C conductor temperature.
