LSZH Cables for Use in Applications Smoke Emission and Toxic Fumes

APPLICATION

These power cables are used for electricity supply in low voltage installation system. They are well adapted to underground use in industrial applications with an additional mechanical protection. These cables can be fixed on cable trays, within conduits or fixed to walls.

CONSTRUCTION

Conductor Up to 35mm2: Class 1 solid copper conductor to 16mm2 Above 35mm2: Class 2 stranded copper conductor

Insulation XLPE (Cross-Linked Polyethylene) Type 2XI1 according to VDE 0276 Part 604 Sheath LSZH (Low Smoke Zero Halogen) Type HM4 according to VDE 0276 Part 604

Main features
1. Ordinary flame retardant cable
For Class A and Class B fire tests, the fire time is 40 minutes, and for Class C and Class D fire tests, the fire time is 20 minutes, and the charring height does not exceed 2.5 m.
2. Low-halogen low-smoke flame retardant cable
Halogen acid gas emission <100 mg/g, smoke density (transmittance) > 30%, from the group burning test, it meets the requirements of Class C flame retardancy.
3. Low smoke zerohalogen (LSZH) flame retardant cable:
Halogen acid gas all-emission 0 mg/g, pH value ≥ 4.3, conductivity ≤ 10 us/mm, toxicity index ≤ 5. From the group burning test, it at least meets the requirements of Class C flame retardancy, smoke density (transmittance) ≥
60%.
4. Oxygen barrier cable (highly-flame retardant cable)
From the group burning test, it meets and exceeds the requirements of Class A flame retardancy, and the smoke density (transmittance) is equal to or close to national standard GB/T17651-2008 and international standard IEC61034 low smoke standard.
It is especially suitable for 6 KV-35 KV medium-voltage cable frame retardancy, has not only flame retardancy up to Class A, but also has certain refractory characteristics (i.e. can still keep 2.4 Uo insulation standard after burning for 20 min).
Notes: Users can select category and class of flame retardant cable according to laying places.
