Description
Technical field
The utility model relates to electrical equipment technical fields, and in particular to a kind of cable.
Background technique
With the rapid development of economy, cable dosage increases sharply, since the fire of the not fire-retardant initiation of cable also increases therewith
Add.To reduce the fire that cable fire causes, guarantee life and property safety of people, all kinds of flame retardant cables come into being, and
And it is widely used in Practical Project.
In routine use, insulating materials used in flame retardant cable generally uses crosslinked polyethylene, and heat resisting temperature reaches
To 100 DEG C or more.Although heat resisting temperature has had reached general flame-retardancy requirements, for a long time in fire hazard environment, electricity
When cable persistently overheating reaches higher temperature, cable can decay more severe in aspect of performance, be unfavorable for personnel evacuate in time with
Escape.
Utility model content
The purpose of the utility model is to provide a kind of crosslinked polyetylene insulated halide-free low-smoke fireproof cables of copper core, solve
At least one above technical problem.
The technical issues of the utility model is solved can be realized using following technical scheme:
The crosslinked polyetylene insulated halide-free low-smoke fireproof cable of copper core, including cable core and the shield being coated on the outside of the cable core
Set, the cable core include conductor and the insulating layer that is coated on the outside of the conductor, which is characterized in that
Heat-sink shell is equipped between the insulating layer and the sheath, the heat-sink shell includes aramid fiber honeycomb paper and is filled in virtue
Microcapsules of storing energy through phase change in the gap of synthetic fibre honeycomb paper.
Aramid fiber honeycomb paper not only has heat-resisting, fire-retardant characteristic, while can also play heat-insulated effect.By setting above
It sets, sheath and cable core is separated with aramid fiber honeycomb paper, in fire hazard environment, slow down the rate that outside heat is transmitted to cable core, with
The electric conductivity of conductor in cable core is maintained, to win more times for evacuating personnel escape.Meanwhile the sky of aramid fiber honeycomb paper
Microcapsules of storing energy through phase change is also filled in gap, microcapsules of storing energy through phase change can absorb the heat outside aramid fiber honeycomb paper and protect
The temperature-resistant of itself is held, to slow down cable core heating.
Optionally, glass fibre is filled between the heat-sink shell and the insulating layer.
Glass fibre high temperature resistant, intensity are high, and the tensile strength of cable can also be improved while improving cable flame retardance.
Optionally, filled with by aluminium hydroxide, magnesium hydroxide and binder group between the heat-sink shell and the insulating layer
At metal hydrate.
Metal hydrate fusing point is 2600 DEG C, and metal oxide and water can be converted under flame, reduces burned electricity
The internal temperature of cable, while remnant is fine and close is wrapped in insulated wire cores, makes it that can not participate in hot oxygen reaction.
Optionally, the insulating layer is the insulating layer made of low-smoke non-halogen flame-retardant crosslinked polyethylene.
Crosslinked polyethylene has good creep resistance, insulation performance and heat resistance, can be under fire hazard environment effectively
Protection conductor makes conductor maintain to work normally.
Optionally, the sheath is the restrictive coating made of low-smoke non-halogen flame-retardant crosslinked polyethylene.
Crosslinked polyethylene heat resistance is good, and when burning does not generate harmful halogen gas, does not generate corrosive gas, fires
Fever amount is few when burning, will not have an impact to evacuating personnel and the process of escape.
Detailed description of the invention
Fig. 1 is a kind of sectional view of the utility model；
Fig. 2 is another sectional view of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
