Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of resistance to fire-retardant resistance to fireproof electric wire and cable, including inner tube 7, there are three cables for setting on the inside of inner tube 7
It is provided with shell 9 on the outside of pipe 4, including inner tube 7, insulating layer 8 has been filled between inner tube 7 and cable tube 4, and insulating layer 8 has
Body is novolac resin layer, and conducting wire is mounted in three cable tubes 4, and shell 9 can play the role of protecting steel pipe 7, insulating layer 8
Design so that the cable the safety is improved, thus service personnel to the cable carry out maintenance process in, will not be because of leakage
Generation that is electric and leading to accident, the personal safety of service personnel are ensured.
9 surface of shell is uniformly connected with multiple elastic pieces 6, and elastic piece 6 is arc setting, and one end of elastic piece 6 with it is interior
