2.Flame retardant control cable
The flame retardant cable is mainly featured in low liability of
fire or that second combustion is only limited to a certain range,
meets the IEC60332 combustion testing requirements, and is
applicable to the places with flame retardant requirement.
3.Flame retardant Product Category
(1)Ordinary flame retardant cable: In the event of fire, the cable
may produce a large amount of corrosive gases and smoke after
combustion, and can be used in general occasions with low flame
retardant requirement. Its flammability has A, B,C, D four
categories, and its cable models are added with ZRA- (or ZA-), ZRB-
(or ZB-), ZRC- (or ZC-), and ZRD- (or ZD-)
before ordinary cable models, respectively.
(2)Low-halogen flame-retardant cable: in addition to maintaining
the general characteristics and electrical properties of the
flame-retardant cable, it also has the following characteristics:
a. low halogen acid gas emissions;
b. low corrosivity;
c. less smoke generated.
Its cable model is added with DDZ- (or DL-) before ordinary XLPE
insulated cables model.
(3)Low smoke zero halogen (LSZH) flame retardant cable: featured
a. no halogen acid gas release;
b. small fuming amount;
c. less corrosive gas generated;
d. good flame retardant property.
4.Flame retardant cable 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 value4.3, conductivity10
us/mm, toxicity index5. From the group burning test, it at least
meets the requirements of Class C flame retardancy, smoke density
(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.
