NHXMH-J & NHXMH-O Cable Click here to view the cable arrow-no-circles.png

Applications Overview

NHXMH-J and NHXMH-O are power cables used in fixed wiring installations with a voltage rating of 300/500V by the Building and Construction industry. They are suitable for a wide range of environments, including dry or moist rooms, in masonry or concrete, in and under plaster, however they are not suitable for underground installation.
This range of cables have an oversheath made from a Low Smoke Zero Halogen (LSZH) materials, making them suitable for installation in buildings with a high concentration of people or valuable property, where improved fire characteristics are needed.

NHXMH-J (earth) / NHXMH-O Cable

NHXMH-J & NHXMH-O cable construction

Conductor Solid copper (Class 1)
Insulation Cross-linked polyethylene (XLPE) Type 2XI1
Filler Halogen-free compound
Sheath Flame retardant halogen free thermoplastic polymer compound Type HM2

Unlike the NHXMH-O cable, NHXMH-J cable contains a green/yellow core which acts as an earth conductor. Both cables have an operational temperature rating of -5oC to +70oC.

NHXMH-O and NHXMH-J cable dimensions

Cables with 3 cores, 4 cores and 5 cores are supplied with the green/yellow core as standard. 7 cores and above are supplied as number coded.

Some of our most popular NHXMH-O and NHXMH-J cable sizes include:
