cross-linked polyethylene (XLPE-TR) insulation.
Insulation Shield: Extruded semi-conducting insulation shield.
Neutral Wires: Coated or uncoated copper concentric neutral wires.
Embedded Jacket: Non-conducting linear low density PE(LLDPE) encapsulating jacket with exturded red stripes.
Optional semi-conducting PE jacket.
Maximum Conductor Temperature
Normal Continuous 90°C
Short Circuit 250°C
•Simultaneous extrusion of strand shield, insulation and insulation shield (triple extrusion, dry curing process) combines to form a virtually perfect cable core eliminating unequal electrical stress.
•XLPE insulation offers low moisture absorption, good chemical resistance, low dielectric loss and high dielectric strength. XLPE-TR offers, in addition, tree-retardant characteristics.
•Cable in Duct (C-I-C)
