Description
Technical field
The utility model is related to a kind of cable, and in particular to a kind of flame retardant cable, belongs to field of cable technology.
Background technology
Cable is typically by several or several groups of wires（Every group at least two）The cable of stranded similar rope, every group
Mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation.Cable has
Interior energization, the feature of external insulation.Cable has power cable, compensating cable, shielded cable, flame retardant cable, computer cable, signal
Cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc..They are all by sub-thread or multiply
Wire and insulating barrier are constituted, and for connecting circuit, electrical equipment etc., are applied respectively in different occasions.
Common in the market and flame retardant cable is general two kinds of implementation methods, and one kind is to use flame retardant type rubber in production process
Jacking replaces general rubber jacking, i.e., fire retardant is added in general rubber jacking and forms flame retardant type rubber jacking, but add fire retardant
Rubber can be caused to cover, and weight increases and mechanical performance declines, and cost is improved；Another embodiment be in conductor copper core directly around
Bag inhibiting tape, five-core cable described above is accomplished by carrying out five wrapped operations, and technique is cumbersome, in high cost, and conductor around
Bag inhibiting tape can hinder radiating of the conductor by insulating barrier.So in existing cable also can not solve simultaneously fire-retardant problem,
Conductor cores heat dissipation problem, and the flame retardant cable structure with the simple feature of around-packing technology.Therefore, exigence is a kind of new
Technical scheme solves above-mentioned technical problem.
The content of the invention
In order to solve above-mentioned problem, the utility model discloses a kind of flame retardant cable, technical scheme structure letter
Single, compact, cable softness is good, good flame resistance, and cost is relatively low, is easy to large-scale popularization and application.
To achieve these goals, the technical solution of the utility model is as follows, flame retardant cable, it is characterised in that the resistance
Combustion cable includes at least three cores, and drainage thread is provided with three cores, and flame retardant cable sets gradually from inside to outside
Blocked water belting layer, flame-retardant layer and restrictive coating, and flame retardant filler is provided between the core.
Used as a kind of improvement of the present utility model, the core includes conductor, insulating barrier and screen layer, the number of the conductor
Amount is at least one.
Used as a kind of improvement of the present utility model, the conductor uses tinned copper conductor, and the insulating barrier is poly- using crosslinking
Vinyl material is made.
Used as a kind of improvement of the present utility model, the belting layer that blocks water is formed by waterstop is wrapped.
Used as a kind of improvement of the present utility model, the screen layer is formed by mica tape braiding.
Used as a kind of improvement of the present utility model, the flame-retardant layer is high-performance refractory fiber.
Used as a kind of improvement of the present utility model, the thickness of the flame-retardant layer is 0.1-0.25mm.
Used as a kind of improvement of the present utility model, the thickness of the screen layer is 0.1-0.3mm.
Relative to prior art, advantage of the present utility model is as follows, and 1）Whole Technical Design is ingenious, and simple structure is tight
Gather, 2）
The refractory material of the technical scheme is refractory inorganic chopped fiber, and such as aluminum oxide will not be hardened, become at high temperature
It is crisp, remain to keep improved flexibility and elasticity, it is ensured that more than 1300 DEG C, fire-resisting cable is in condition of high temperature insulating barrier for high temperature resistant
Structure is intact, therefore hot-face insulation performance is basically unchanged under can keeping high temperature；3）The cable shield is formed by mica tape braiding,
Substantially increase the performance of cable；4）The technical scheme cost is relatively low, is easy to large-scale popularization and application.
