Description
Technical field
The utility model relates to a kind of wire and cable more particularly to a kind of strong smart grid digital transformer substation are extraordinary
Cable.
Background technique
Maincenter of the digital transformer substation as smart electric grid system, be transmission and distribution networks information source and execute terminal,
Therefore it is required that the integrated control measure of information content and realization that substation provides is more and more.Digital transformer substation special cable
It is the key that corollary equipment in smart grid network system, carries power Transmission and information transmission, control, the multiple function fed back
Can, it is the nervous centralis of digital transformer substation and " blood vessel " for maintaining normal operation, is directly related to smart grid digitlization and becomes
Safety, reliability, advance and the economy in power station.Existing traditional cable does not adapt to the Special Ring of digital transformer substation
Border requires.Although some such as corrosion-resistant, the wear-resisting characteristics using increased cable of modified silicon rubber material in the cable,
Such as patent CN201610303956.8 (a kind of high fire-retardance anti-corrosion modified silicon rubber cable material), patent
CN201610303957.2 (a kind of wear-resisting modified silicon rubber cable material of high fire-retardance), a kind of CN201410670196.5 (high resistant
Fire high abrasion modified silicon rubber cable material) disclosed in.But it is also insufficient to the use of these technologies, it is sometimes practical
In use process, cable is not still able to satisfy practical matter, such as the use of Power Network Digital substation.
Utility model content
Purpose of utility model: problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of strong
Smart grid digital transformer substation special cable has excellent high-low temperature resistant, flame-retardant, ageing-resistant, corrosion-resistant, signal
The performances such as high, the high anti-interference and long service life of transmission rate.
Technical solution: a kind of cable successively includes cable core, high stop band wrapping layer, liner layer, armor and outer from inside to outside
Sheath；The core of looking at is twisted by power wire core, control conductor, instrument core and filled layer.
Further, the power wire core from inside to outside successively include the first conductor, the first flame retardant coating, the first insulating layer,
Aluminium foil wrapping layer, the first proof copper-wire braided shielded layer and sheath.
Further, the control conductor from inside to outside successively include the second conductor, the second flame retardant coating, second insulating layer,
Inhibiting tape wrapping layer and the second proof copper-wire braided shielded layer.
Further, the instrument core from inside to outside successively include third conductor, third flame retardant coating, third insulating layer,
Pair twist wrapping layer and third proof copper-wire braided shielded layer.
Further, the armor is that finer wire weaves armor.
Further, the oversheath is modified silicon rubber oversheath.
Further, the first, second and third proof copper-wire braided shielded layer is tinned copper wire woven shield.
Further, the liner layer is made of modified silicon rubber.
Further, first, second and third flame retardant coating is fireproof mica layer.
The utility model has the advantages that the cable of the utility model has the following technical effect that
1, the special cable integrates three electric power, control, instrument unit cables, is shielded each other using independent split-phase
Isolation structure prevents electromagnetic interference, while reducing the occupied space of cable, thus on the basis of guaranteeing performance to greatest extent
Ground optimizes the construction of cable, reduces cable dosage.
2, it since power unit field strength is higher, is affected to communication unit, therefore, is increased after power unit stranding
Tinned copper wire braid shielded keeps communication unit continuous in signals transmission, stable, reliable.Meanwhile outside cable inner sheath
Finer wire braiding is increased again, has been not only acted as armouring effect, has been also played the effect always shielded, has kept whole cable and the external world mutual
It does not interfere, ensure that accuracy, reliability and the high-speed of signal transmission.
