It is a focused low-voltage product page rather than a catch-all Type 441 listing: the source gives one voltage designation, one Class 2 construction and its own area, diameter and mass tables.<\/p>\n<p>The construction combines three flexible tinned-copper power cores, three interstitial earth cores and one central pilot. Power-core insulation is Class 2 EPR R-EP-90 with a semiconductive layer; the cores are laid over a semiconductive cradle. The earth cores are not insulated, and the assembly is completed by semiconductive elastomer bedding, an open-weave reinforcing braid and a heavy-duty elastomer outer sheath.<\/p>\n<p>Selection should start with the 1.1 kV machine supply and the required conductor area, then move to the cable-entry, support and handling conditions. The datasheet records a 4.2 kV test voltage, but it does not provide current capacity, bend radius, pulling load or travel speed.
