Description
Technical field
The utility model relates to a kind of cable, specifically a kind of extraordinary polyolefin jacket fireproof cable.
Background technology
According to data, in the fire that China occurs, because the fire electrically caused accounts for the half of total fire number, because cable is aging or overload uses the fire caused to account for larger proportion in electrical fire, simultaneously because the toxic gas sent during fire shot-firing cable can cause mass casualties, and hinder fire fighter to put out a fire, it is very important for therefore correctly designing fire-resisting cable.
The existing construction of cable comprises many conductors, be coated on insulating barrier, braid and restrictive coating four parts outside each conductor, wherein, conductor and insulating barrier form insulated wire cores, and braid is wrapped in the outside of many insulated wire cores, and restrictive coating is coated on the outer surface of braid.
In signals transmission, the fire resistance of the cable of this structure is poor, when running into high temperature environmental activity on fire, can cause huge potential safety hazard.
Utility model content
In order to make up the deficiencies in the prior art, the utility model provides a kind of moulding process, concise production process, convenience, and without special equipment, and fire resistance is good, and cost is low simultaneously, good in economic efficiency fireproof cable.
The utility model solves the technical scheme that its technical problem adopts: a kind of extraordinary polyolefin jacket fireproof cable, comprise insulation core wire, mylar tape, ground wire, extraordinary composite band and sheath, described insulation core wire is made up of conductor and the inner insulating layer be wrapped in outside conductor, described inner insulating layer is flame-retardant crosslinking polyethylene insulated material, it is right that described every two bar insulation heart yearns are twisted into, two pairs of insulation core wire set strandings.
Further, described insulation core wire is wrapped with mylar tape.
Further, ground wire is placed with outside described mylar tape.
Further, described ground wire is made up of the tinned copper wire of 0.5mm diameter.
Further, the extraordinary composite band of the outer wrapped multilayer of described ground wire.
Further, the extraordinary composite band of described multilayer comprises ceramic silica gel composite band, ceramic polyolefin composite band and multi layer cloud master tape.
Further, the extraordinary composite band of described multilayer is wrapped with sheath.
Further, described sheath is extraordinary polyolefin jacket.
The cable that the utility model provides, adopt flame-retardant crosslinking polyethylene, save thermosetting, elastomeric mixing, moulding process, concise production process, convenience, without special equipment, and adopt new special polyolefin jacket, fire resistance is good, cost is low, good in economic efficiency simultaneously, can in IEC60331-23,750 DEG C of environment, 180 minutes fire-resistant passes through, and adopt ceramic silica gel composite band, ceramic polyolefin composite band and mica tape multilayer wrapped, can melt when high temperature and be polymerized to hard flame retardant coating, fire-resistant better effects if.This cable can be used for the transfer of data of fire alarm system.
