Nexans HEPR-SHF1 3,6/6 and 6/10kV 1x300mm2

Application

Nexans HEPR-SHF1 cables are ideal for applications in isolated power supply and distribution circuits in substations, industrial and commercial installations. They can be installed in a variety of conditions, including outdoors, in conduits, ducts, underground installations, duct banks or trays. Because they have fire-retardant characteristics combined with low smoke and toxic gas emissions - which represent the greatest risks in a fire - they are suitable for installations in places with high occupancy density and difficult escape conditions. In addition, they have a coordinated insulation thickness, in accordance with NBR 6251, which results in reduced external dimensions compared to conventional cables insulated with EPR, HEPR or XLPE.

Construction

1.Conductor: Formed by bare copper wires, minimum conductivity 100% IACS, soft quenching, compacted stranding class 2 compliant.

2.Conductor shielding: Extruded semi-conductor thermosetting compound.

3.Insulation: High-modulus ethylene-propylene compound (HEPR), for a maximum temperature of 90ºC at all times.

4.Insulating shielding: Non-metallic shielding based on extruded semi-conductive thermosetting compound, easily removed when cold and manufactured using a triple extrusion process and a nitrogen dry curing system.

5.Metallic shielding: Consisting of copper wires, helically applied to the insulating shielding, with a minimum cross-section of 6 mm2 according to NBR 6251. For different shielding sections, please consult in advance.

6.Sheath: Non-halogenated thermoplastic compound, type SHF1, in black.
