DESCRIPTION
electric cable formed by a set of several aluminum conductors electrical grade, compact wiring, each insulated special weatherproof composite crosslinked polyethylene (XLPE), twisted around a carrier element consisting of a rope aluminum alloy with or without XLPE insulation which also serves as the neutral conductor.
The assembly may also incorporate one or more additional conductors for street lighting.
IDENTIFICATION OF DRIVERS
Each phase conductor is identified with marks on the extruded insulation (1 mark for phase 1, 2 marks for Phase 2 and 3 marks for phase 3).
When two additional drivers in the same section one is identified with 4 marks requested.
APPLICATION
The Multi-Autoportantes Aluminum Conductors, IAAC, cables are used for overhead electrical distribution networks of low-cost energy in urban and rural areas.
Both poles are installed as apposed to walls, in both cases, with appropriate accessories. Not require the use of isolators.
STRESS DESIGN
U0 / U = 0.6 / 1 KV
OPERATING TEMPERATURE
90 ° C on the conductor, for continuous operation.
130 in emergency conditions.
250 ° C in short circuit conditions.
TECHNICAL SPECIFICATIONS
•
NTP 370254
•
ASTM B399-04
SPECIAL PRECAUTIONS
It is recommended not to use these cables in areas of saline or polluted environment, given the poor corrosion resistance of aluminum.
Referrals and connections with copper cables should be done by using appropriate techniques.
During installation work must be careful not to damage the surface of the cable.
