What is DURESCA

Per Definition: DUR = SolidRES = ResinCA = Casting

InsulationCrepped paper, dried and vacuum impregnated with epoxy resin

Ground shieldAluminium foil, enhanced with copper braid

Protecting envelopeCorrugated polyamide pipe, resistant against water and UV radiation (max. dia. 146 mm or 3800 A)

Ruggedized outside envelopeAluminium pipe or corrugated stainless steel pipe (max. dia. 258 mm or 7500 A)


10/23/03 / TP

Protecting envelope

Ground shield



Choice of Conductor

Aluminium anticorodal (AC041 - EWAA no. 6101) is better suited than copper because of the following reasons:

Mechanical characteristicsCopper must be heavily heated for bending and welding with loss of mechanical strength

Reduced weightFor the same nominal current, the aluminium busbar is lighter (AC041 = 2.7 kg / dm3, copper = 8.9 kg / dm3)

Reduced priceThe aluminium version is about 10 - 15 % cheaper

Thermal dilatation coefficientCopper 12 x 10-6 / KAC041 23 x 10-6 / KDURESCA 30 - 40 x 10-6 / K

DURESCA and TIRESCA for Marine - Application

10/23/03 / TP

Radiance of the Seas Jos. L. Mey er GmbH

For marine systems the production and distribution of electrical Energy is of prime importance. Limited space availability must be considered during design.Operating safety and fire resistance are important considerations

The highest demands for safety and reliability under continuous load, is what MGC Technology Ltd.. offers together with complete protection for operatingpersonnel and maximum space saving.

The compact method of construction allows minimum bending radii and a three dimensional busbar arrangement without expensive supports.

The optimal busbar arrangement, quick installation and maintenance free design provide a most economical solution.
