NHXMH-O / -J  300/500V Halogen Free light weight cable
Standards
International  IEC 60228; IEC 60332-3-22; IEC 60754-1; IEC 60754-2; IEC 61034
National  DIN VDE 0250 part 214; DIN VDE 0250 part 214
Description

Applications

For fixed installation on ships and offshore-units in all locations below the upper metallic deck, especially in chambers for secondary circuits.
A more specific design (e.g. screening) is necessary for installations in radio stations or above the upper metallic deck.
The cables meet the flame test requirements for bunched cables acc. to IEC 60332-3-22 and IEEE 45-18.13 and perform to the SOLAS requirements. All cable materials are free of halogens.This design ensures that non corrosive and low toxic gases are emitted in case of fire. Therefore, these cables are especially suitable for the installation on passenger ships.

 

Design

  1. Conductor: solid bare copper class 1
  2. Insulation: XLPE (cross linked polyethylene)
  3. Common covering
  4. Outer sheath: cross-linked polyolefin, light grey

 

Marking

e.g.: l NEXANS l ‹VDE›NHXMH 3 x 1,5 300/500 V IEC 60332-3 CAT. A

 

Core Identifikation

According with DIN VDE 0293-308
1 core: black
2 cores: blue/brown
3 cores: brown/black/grey
