0.6/1 KV XLPE / LSHF Low Smoke Halogen Free Power Cable Underground
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.
