Aerial Bundled Cables
LV-ABC is a novel concept for over-head power distribution. Compared to bare overhead conductor distribution system, ABC provide higher safety and reliability, self-supporting and suspended between supports, lower power losses and ultimate system economy by reducing installation, maintenance and operating costs. ABC distribution system is ideal for rural distribution, urban areas, hilly areas, forest and costal areas.
In the voltage designation of U0/U(Um) , the rated voltages of the cables considered in BS and NFC standards are as follow: U0/U(Um)=0.6/1(1.2) KV. U0 is the rated power frequency voltage between conductor and earth; Construction features: - Size : Phase : 16 to 150 sq.mm. Neutral messenger: 35 to 95 sq.mm. Street lighting : 16 to 35 sq.mm. (If applicable.) -Conductor material : Phase : Aluminum Neutral messenger: Aluminum alloy Street lighting : Aluminum. (If applicable.) -Conductor type : Phase : Circular compacted Neutral messenger: Circular compacted/uncompacted Street lighting : Circular compacted. (If applicable.) -Insulation: Extruded XLPE or HDPE, black ( UV absorber ) , weather resistant. -Design: The cable consists of one, two or three insulated phase conductors and one or two optional insulated street lighting conductors stranded around the bare or insulated neutral messenger. - Core identification with longitudinal ridges Standards : BS 7870 , NFC 33-209
U is the rated power frequency voltage between conductors;
Um is the maximum value of the "highest system voltage" for which the equipment may be used.
