Description
Technical field
The utility model relates to the bus cable technical field, relates in particular to a kind of stranded copper core conductor full-shield wire armoring A type FF fieldbus cable.
Background technology
In recent years, the copper output of China is far below demand, and the copper valency is rising violently always on the market.Current, the shielding material majority of fieldbus cable is a copper, and its cost is higher.In the prior art, it is shielding high-frequency signal electric current that the screen of bus cable mainly acts on, and high-frequency current on conductor through the time can produce " kelvin effect ", promptly 80% above electric current flows through at conductive surface.With the copper cover aluminum wire rod screen that braiding forms as shielding material; Maskable plays the non-signal high-frequency current of interference effect; Concrete, non-signal high-frequency current is through the appearance copper laminar flow mistake of copper cover aluminum wire rod, and its shield effectiveness is with identical with the screen of solid copper wire braiding.On the other hand, the price of copper-clad aluminum conductor is below 50% of solid copper wire price, therefore, can consider that shielded type cable application copper cover aluminum wire rod as shielding material, can significantly reduce the cost of bus cable like this.
Based on said consideration, how a kind of bus cable that adopts the copper cover aluminum wire rod as shielding material is provided, reduce the cost of bus cable, and have good anti-interference, become the technical problem that those skilled in the art continue to solve.
The utility model content
To above-mentioned defective, the utility model purpose is to have proposed a kind of stranded copper core conductor full-shield wire armoring A type FF fieldbus cable, reduces the cost of bus cable, and has good anti-interference.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of stranded copper core conductor full-shield wire armoring A type FF fieldbus cable comprises two copper conductors, two gasket for packings, and every copper conductor is by seven copper cash stranded compositions, and is enclosed with insulating barrier at every copper conductor outer surface; Two copper conductors, two gasket for packings are oppositely arranged and occupy the circumference of same circle respectively, and outside to adopt aluminium/mould composite membrane to carry out wrapped at it, and the metal covering of aluminium/mould composite membrane is provided with outwardly; The cable length direction is placed seven copper wire earth connections in the metal covering upper edge of aluminium/mould composite membrane; At the outer wrap of aluminium/mould composite membrane, copper wire earth connection screen by the establishment of copper cover aluminum wire rod; Be enclosed with inner restrictive coating at the screen outer surface; At the inner restrictive coating outer surface armour is set, is enclosed with external sheath layer at the armour outer surface.
Preferably, said screen has the tin-coated copper plated aluminium wire rod to work out.
Preferably, establishment density >=80% of said copper cover aluminum wire rod.
Preferably, said insulating barrier adopts foaming-Pi polyethylene layer.
Preferably, said gasket for packing is the PE gasket for packing.
Preferably, said copper wire earth connection is the tinned copper wire earth connection.
Preferably, said inner restrictive coating, external sheath layer are the PVC protective sleeve.
Preferably, adopt zinc-coated wire as armour.
Compared with prior art, the utlity model has following beneficial effect:
A kind of stranded copper core conductor full-shield wire armoring A type FF fieldbus cable that the utility model proposes; Reduce the cost of bus cable; The appearance copper layer that plays the non-signal high-frequency current process screen copper cover aluminum of interference effect flows out through earth connection, and it has good anti-interference effect.The screen outer wrap of tin-coated copper plated aluminium wire rod braiding inner restrictive coating and external sheath layer, screen is hedged off from the outer world, avoid the tin-coated copper plated aluminium wire rod to receive atmospheric corrosion and mechanical damage.The copper cover aluminum wire rod has increased its corrosion resistance through zinc-plated processing.
