APPLICATION
Primary and medium voltage distribution circuits for industrial and commercial plants, electric power generators, power supply for transformers, motors and equipment.
Preferably used in urban networks.
EATs are appropriate for applications where greater flexibility is needed than that of XATs.
STANDARD
ICEA S-93-639
VOLTAGE
5 kV, 8 kV, 15 kV, 25 kV, 35 kV
CONSTRUCTION
1.Conductor:Compacted copper conductor per ASTM B496 Or ASTMB835
2.Internal Semiconductor Screen:Extruded on the conductor
3.Insulation
Tree retardant cross-linked polyethylene (XLPE-TR) for XAT.Ethylene Propylene Rubber (EPR)for EAT.Both compounds are natural in color and are applied by true triple extrusion process.The isolation level can be 100% or 133%
4.External Semiconductor Screen:Extruded, with adequate adhesion to the insulation that makes it easy to peel
5.Metal Screen:It can be formed by a copper tape or by copper wires, both applied helically
6.Outer Cover:Black PVC. Other colors and compounds available upon request.
Operating Characteristics
Maximum service temperature: 90 °C
Emergency overload temperature:130°C
Short circuit temperature: 250 °C
Flexibility: Compacted conductor
In addition to the above,these cables have the following characteristics:
-Good tensile strength.
-High resistance to impact and abrasion.
-Excellent resistance to sunlight and weather
-Very high resistance to humidity, ozone, acids, alkalis and other sus-chemical substances at normal temperatures.
-Low dielectric constant, low loss factor and high resistance of isolation.
-The cover is flame retardant.
