Aerial Insulated Protected Cables Application
In continuous regime:90℃
In overload:100℃
In short circuit:250C
Aerial Insulated Protected Cables Reference Standards
ABNT NBR 11873 - Cables covered with polymeric material for power distribution networks fixed in spacers, in voltajes from 13,8 to 34.5 kV.
ABNT NBR NM280-Conductors of insulated cables (IEC 60228, MOD).
Aerial Insulated Cables/Protected Cables with voltages from 13.8kV - 34.5kV of spacer cable. Protected Cables is suitable for compact primary networks of medium voltage power distribution. The protected cable coverage is resistant to electrical tracking and weather. This increases the reliability of the overhead line distribution, which prevents discharges and shutdowns, in occasional contacts with grounded objects and trees.
Aerial Insulated Protected Cables Construction
Conductor: 1350 aluminum wires, compact class 2 cording, with longitudinal moisture blocking,according to NBR NM 280.
Semiconductor layer: Thermostable material (XLPE) or thermoplastic (PE) (even for 35 kV cables, optional for 15 and 25kV cables).
Protective layer: This cover, applied simultaneously with the semiconductor layer, can be made up of one or two layers of thermostable material (XLPE), or two layers of polyethylene LDPE/HDPE or XLPE/HDPE. in the case of cables that have two layers. , the internal one will be colorless and the external one will be the one that has the indicated coloration.
