AERIAL BUNDLED CABLES (ABC) (AER)
The usage of ABC Cables in low voltage Networks provides important saving in installation costa while it ensures the same reliability and safety replaces bare-conductors in overhead distribution lines and increased very rapidly since 1960 all round the world.
PHASE CONDUTORS
Phase Conductors are manufactured round,solid aluminium wires. 16 mm2 round solid aluminium , 25…..95 mm2 from 7 wires ,120 mm2 and up 19 wires round stranted and compacted aluminium Tensile and Strenght 120 N/mm2 , Resistivity at 20 C max.0,028264 ohm mm2/m
NEUTRAL – MESSENGER
Neutral – Messenger ,manufactured with 7 wires from aluminium alloy. Tensile and Strenght 294 N/mm2 , Resistivity at 20 C 0,03284 ohm mm2/m
INSULATION
ABC (AER) Cables , phase conductors extruded black weather-resistant special low density PE or XLPE.The insulated phase conductors are signed by continous salient lines.In all types of cables 1 salient line shows neutral within 5 insulated cores.The salient lines 2-3-4 shows phase.
MARKING
Manufacturer name,size,rated voltage,TSE guaranty mark,Standard no. and manufacturing year of the cable embossed on the insulation of two ridgephase conductor
AER 3*50+1*16+70 mm2 0.6 / 1 kV TSE TS 11654 (Production Date)
USAGE PLACES
ABC (AER) Cables in an excellent solution for rural and industrial areas.Stage lighting at main roads and streets.House,Apartment Village,Small Town and industrial areas. In the areas of protection of the trees. Contact with trees do not cause short-circuits.
RELIABILITY
ABC (AER) Cables are safier comparing to overhead transmission line terms of life and good security ABC (AER) Cables never give permission to illegal usage of electricity ABC (AER) Cables can be used in foresty regions without cutting down the trees ABC (AER) Cables can be used on wooden,concrete and iron columns and columns heights can be shorter Short-circuits are very rare in the ABC (AER) Cables
SAFETY
Being insulated , ABC (AER) Cable is not dangerous to person who touch it unawares.In this aspect it differs essentially from bare-conductor lines.This is an important advantage for both fitters and others who live or work nearby. Also kWH meters are beter secured against atmospheric overvoltages when using ABC (AER) Cables The Neutral of ABC (AER) Cable is uninsulated.The neutral is easily and unmistakably identifiable when low-voltage lines are being installed or repaired.
COSTS
The erection costs of a fully installed ABC (AER) line are lower than those of a correspnding bare-conductor line.The ABC (AER) saves money on labour costs,accesories,tools and total investment.So it is the solution when max.line kilometrage form in.investment and labour input sought. ABC (AER) Cable lines are also cheaper than a bare-conductor lines for operating and maintenance costs. Several ABC (AER) Cables can be installed on the same pole.Due to this distrubition capacity can be increased later. Telephone Cables or medium voltage overhead power cables can be installed on the same pole with ABC (AER) Cables.
Lower inductive reactance of the ABC (AER) Cables reduces voltage drop and power losses Due to the fewer interruption on the ABC (AER) lines lower consumtion losses and customer complaints. The insulated phase conductors of ABC (AER) cables prevent illegal usage of electricity.
