The difference between fireproof cable and fireproof cable

The biggest difference between fire-resistant cables and fire-resistant cables is that fire-resistant cables have an extra layer of mica than fire-resistant cables, while fire-resistant cables have no mica. Fire-resistant cables can maintain normal power supply (use) for a period of time when a fire occurs, while flame-retardant cables do not. With this feature, most fire-resistant cables refer to flame-retardant cables.

Fireproof cable: Under the specified test conditions, the sample is burned. After the test fire source is removed, the flame spread is only within a limited range, and the residual flame or residual burn can be extinguished within a limited time. The characteristics of the fireproof cable are: In case of fire, it may be burned out and cannot be operated, but it can prevent the spread of fire. That is to say, if the cable catches fire, it can limit the burning to a local area, prevent the spread, and protect other various equipments to avoid causing greater loss.

Main models of fireproof cable:

NG-A; Isolation type copper core aluminum sheath inorganic mineral insulation halogen-free low-smoke flame retardant polyolefin outer sheath fire-resistant cable;

BTLY; copper core aluminum sheath inorganic mineral insulated halogen-free low-smoke flame retardant polyolefin outer sheath fire-resistant cable;

YTTW; copper core embossed copper sheath inorganic mineral insulated flexible fireproof cable;

BBTRZ; copper core mica plus ceramic silicon rubber compound tape insulation halogen-free low-smoke flame-retardant polyolefin outer sheath fire-resistant cable

BTTZ; copper core copper sheath magnesium oxide insulated fireproof cable;
