Abstract
The invention discloses a direct-current conducting wire. The direct-current conducting wire is mainly composed of aluminum alloy conductor wire cores, a semiconductive filled layer, a steel tape armor polyethylene sheath layer, an aluminum tape shielding layer, a chlorosulfonated polyethylene sheath layer and a chloroprene rubber sheath layer. The aluminum alloy conductor wire cores are twelve in number and are stranded together and wrapped in the semiconductive filled layer, the steel tape armor polyethylene sheath layer is wrapped outside the semiconductive filled layer, the aluminum tape shielding layer is wrapped outside the steel tape armor polyethylene sheath layer, the chlorosulfonated polyethylene sheath layer is wrapped outside the aluminum tape shielding layer, and the chloroprene rubber sheath layer is wrapped outside the chlorosulfonated polyethylene sheath layer. The direct-current conducting wire has good electromagnetic compatibility and a good bending effect, the shielding layer of the direct-current conducting wire can prevent electromagnetic wave interference, and when a circuit is shorted out, the highest temperature of wire conductors is less than 180 DEG C.
Description
Technical field
The present invention relates to field of cables, relate in particular to a kind of DC wire.
Background technology
At present; the cable using in air equipment instrument; all very high to the each side quality requirement of cable; because very important of fail safe in these fields; generally not admit of potential safety hazard to exist; in these fields, just should use so some short-circuit protection performance, electromagnetic compatibility and anti-interference aspect strong cable, can better ensure and improve fail safe.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of DC wire of the advantage with electromagnetic compatibility and strong interference immunity.
The present invention takes following technical scheme to realize: a kind of DC wire, it is mainly by aluminium alloy conductor core, semiconductive packed layer, steel-tape armouring pe sheath layer, aluminium strip screen, chlorosulfonated polyethylene sheath layer and chloroprene rubber sheath layer composition, described aluminium alloy conductor core has 12 groups, outside twisting together, be enclosed with one deck semiconductive packed layer, outside described semiconductive packed layer, wrap up one deck steel-tape armouring pe sheath layer, outside described steel-tape armouring pe sheath layer, be enclosed with one deck aluminium strip screen, outside described aluminium strip screen, be enclosed with one deck chlorosulfonated polyethylene sheath layer.
Described aluminium alloy conductor core is made up of albronze conductor, copper strip shielding layer, low-smoke halogen-free polyolefin restrictive coating, ethylene propylene rubber insulated layer and zinc-plated shielding layer of copper wires.
The present invention has following beneficial effect in sum: this cable has good electromagnetic compatibility, and bending effect is good, and this cable shield can prevent Electromagnetic Interference, if when short circuit, the maximum temperature of cable conductor is no more than 180 DEG C.
Brief description of the drawings
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, aluminium alloy conductor core; 2, semiconductive packed layer; 3, steel-tape armouring pe sheath layer; 4, aluminium strip screen; 5, chlorosulfonated polyethylene sheath layer; 6, chloroprene rubber sheath layer.
Embodiment
As shown in Figure 1, a kind of DC wire, it is mainly by aluminium alloy conductor core 1, semiconductive packed layer 2, steel-tape armouring pe sheath layer 3, aluminium strip screen 4, chlorosulfonated polyethylene sheath layer 5 and chloroprene rubber sheath layer 6 form, described aluminium alloy conductor core 1 has 12 groups, outside twisting together, be enclosed with one deck semiconductive packed layer 2, outside described semiconductive packed layer 2, wrap up one deck steel-tape armouring pe sheath layer 3, outside described steel-tape armouring pe sheath layer 3, be enclosed with one deck aluminium strip screen 4, outside described aluminium strip screen 4, be enclosed with one deck chlorosulfonated polyethylene sheath layer 5.
Described aluminium alloy conductor core 1 is made up of albronze conductor, copper strip shielding layer, low-smoke halogen-free polyolefin restrictive coating, ethylene propylene rubber insulated layer and zinc-plated shielding layer of copper wires.
The permission bending radius of this cable is the outside diameter of cable 10 times; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.
The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
