Description
Technical field
It the utility model is related to field of cable technology, more particularly to a kind of flame resistant cable.
Background technology
At present, with the development of science and technology, people are also more and more to the demand of cable, and cable is a kind of common number
According to signal transmission apparatus, have the advantages that message capacity is big, transmission stability is high and security performance is good, but existing cable is protected
Sheath uses some more universal polymer, and not only service life is short, but also can there is a situation where to pollute environment.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of flame resistant cable, including leads core, its feature exists
In further including criss-cross reinforcer and the arc stop part positioned at the reinforcer end, the angle of the reinforcer
The binding agent that blocks water is scribbled, the adhesive surface that blocks water is stained with water-proofing powder, and the quantity for leading core is for 4 and by the reinforcement
Part separates, and the core of leading is coated with insulating layer, and water-swellable waterstop, the block piece outside are coated with the outside of the insulating layer
Equipped with shielded layer, flame-retardant layer, armor, fire prevention filled layer and steel band interlocking are extruded with outside the shielded layer successively from the inside to the outside
Armor, the steel band lock armo layer outside are socketed with oversheath.
Thus, single lead is coated with insulating layer and water-swellable waterstop on core, and is reinforced part and separates, and greatly improves
The water preventing ability of cable, it is single lead the water-swellable waterstop water-swellable that is coated on core after its deformation receive reinforcer and house type
The limitation of block piece, avoiding remaining from leading between core and lead core and gap occur with shielding interlayer causes cable axially to be intake；Strengthen
The setting of part ensure that the tensile strength of cable, improve its bearing capacity.
As a preferred embodiment, the reinforcer includes retaining wall, the arc stop part includes being symmetricly set on the retaining wall
The curved portion of both sides.
As a preferred embodiment, the reinforcement material is polyethylene.
As a preferred embodiment, the shielded layer is silicon rubber, the shielded layer inner homogeneous is provided with high-carbon steel wire.
Thus, the waterproof of silastic-layer, mould proof ability are strong, have enough bending properties, and internal arrangement sets high-carbon steel
Silk, reduces the excess loss of cable electric energy, improves its current-carrying capacity.
As a preferred embodiment, the fire prevention filled layer is fire-resisting ceramic silicone rubber.
Thus, fire-resisting ceramic silicone rubber layer is set between armor and steel band lock armo layer, being capable of jail after ablated
Cable is protected in jail, avoids electric wire breakdown.
As a preferred embodiment, it is filled with polypropylene filling rope in the shielded layer.
Thus, the cable after filling has good electric insulating quality and flexibility, and resistance to corrosion is strong.
To sum up, the utility model has the following advantages：Single lead is coated with insulating layer and water-swellable waterstop on core, and
It is reinforced part to separate, substantially increases the water preventing ability of cable, it is single to lead the water-swellable waterstop water-swellable coated on core
Its deformation is limited by reinforcer and arc block piece afterwards, avoids it from leading between core and lead core and gap occurs with shielding interlayer
Cable is caused axially to be intake；The setting of reinforcer ensure that the tensile strength of cable, improve its bearing capacity；Armor and steel
Fire-resisting ceramic silicone rubber layer is set between band lock armo layer, cable can be firmly protected after ablated, avoid electric wire
It is breakdown.
Brief description of the drawings
