Abstract
The utility model discloses a kind of flame retardant type multiple twins to shield cotton covered wire, including oversheath, and the metal screen layer and fire-retardant separation layer that are sequentially placed into the oversheath from outside to inside；The fire-retardant separation layer is wrapped on four cores, and packing material is filled between the fire-retardant separation layer and the core；Four cores are twisted into round cable core clockwise；The every core includes conductor, and the PE insulating layer being extruded in outside the conductor.There can be excellent flame retardant property under the premise of meeting mechanical performance and electrical property.
Description
Technical field
The utility model relates to electric wires.
Background technique
In production and living, cotton covered wire is the basis of the continuous runnings such as various electrical equipments.So electric wire should have centainly
Flame retardant property, to solve the transmission problem of electric power under fire condition.
Current electric energy and information are the Two Mainstays of society, and the either transmission of electric energy or information all be unable to do without electric wire
Cable.And the answering in electric system, skyscraper, industrial and mining enterprises, town and country distribution and communication network extensively with wire and cable
With.Because the fire incident that wire and cable causes also happens occasionally, and the disaster of most serious is the intensity of a fire along cable after fire generation
The sprawling of route.Therefore, control and reduce generation the going on smoothly with important to guarantee building of the four modernizations of wire and cable fire
Realistic meaning, while also have become ensure social public security a significant problem.
Summary of the invention
A kind of flame retardant type multiple twin shielding cotton covered wire is provided the purpose of the utility model is to overcome the defect of the prior art,
There is excellent flame retardant property under the premise of meeting mechanical performance and electrical property.
Realizing the technical solution of above-mentioned purpose is:
A kind of flame retardant type multiple twin shielding cotton covered wire, including oversheath, and be sequentially placed into the oversheath from outside to inside
Metal screen layer and fire-retardant separation layer；
The fire-retardant separation layer is wrapped on four cores, filled with filling between the fire-retardant separation layer and the core
Material；
Four cores are twisted into round cable core clockwise；
The every core includes conductor, and PE (polyethylene) insulating layer being extruded in outside the conductor.
Preferably, the conductor is twisted by more copper wire synnemas；
The fire-retardant separation layer is halogen-free flameproof twining package tape；
The metal screen layer is shielded and is wrapped in outside the fire-retardant separation layer using proof copper-wire braided.
Preferably, the oversheath is extruded in outside the metal screen layer using halogen-free and low-smoke flame-retardant polyolefin sheathed material.
Preferably, the packing material is mineral wool rope.
The beneficial effects of the utility model are: the utility model can effectively prevent or delay fire using effective design
The sprawling of flame meets flame-retardancy requirements, and twining package tape is halogen-free flameproof twining package tape, can continue to hinder in the case where oversheath is destroyed
Only propagation of flame, to guarantee the sustainable stable power supply of conductor.To avoid the generation of more serious fire incident.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the flame retardant type multiple twin shielding cotton covered wire of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Referring to Fig. 1, the flame retardant type multiple twin of the utility model shields cotton covered wire, including oversheath 6, and from outside to inside according to
The secondary metal screen layer 5 and fire-retardant separation layer 4 set in oversheath 6.Fire-retardant separation layer 4 is wrapped on four cores, fire-retardant isolation
Packing material 3 is filled between layer 4 and core.Packing material 3 is mineral wool rope.
Four cores are twisted respectively with red, yellow, green, blue color polyester belt split-phase with red, yellow, green, blue colo(u)r streak core clockwise
At round cable core, remaining gap is filled by packing material 3.Every core includes conductor 1, and the PE being extruded in outside conductor 1 exhausted
Edge layer 2.Conductor 1 is twisted by more copper wire synnemas.
Fire-retardant separation layer 4 is the halogen-free flameproof twining package tape of wrapped PE insulating layer 2.It can be the case where oversheath 6 be destroyed
Under continue prevent propagation of flame.Metal screen layer 5 is shielded and is wrapped in outside fire-retardant separation layer 4 using proof copper-wire braided.Oversheath 6 is adopted
It is extruded in outside metal screen layer 5 with halogen-free and low-smoke flame-retardant polyolefin sheathed material.The sprawling of flame can be effectively prevented or delay, it is full
Sufficient flame-retardancy requirements.To guarantee the sustainable stable power supply of conductor.
Above embodiments are only for illustration of the utility model, rather than limitations of the present invention, related technical field
Technical staff can also make various transformation or modification in the case where not departing from the spirit of the utility model, therefore it is all
Equivalent technical solution also should belong to the scope of the utility model, should be limited by each claim.
