Abstract
The invention discloses a major loop power cable for a frequency converter. The major loop power cable comprises aluminum conductors, an inner insulating layer, a filling layer, a shielding layer, copper conductors, an outer insulating layer and a sheath. The inner insulating layer is wrapped on the aluminum conductors to form three cable cores, the filling layer is wrapped on the three cable cores, the shielding layer is wrapped on the filling layer, and the copper conductors are evenly arranged in the shielding layer in an extruding mode. The major loop power cable for the frequency converter has excellent electromagnetic compatibility, ageing resistance and oil resistance, and further has the good damp resistance function and the good water resistance function; the stability of the insulating strength of the cable can be protected; the service life of the cable is prolonged safely and reliably.
Description
Technical field
The present invention relates to field of cables, relate in particular to a kind of main-loop power cable for frequency changer.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as iron and steel, chemical industry, power plant, papermaking, electromagnetic compatibility, resistance to ag(e)ing, the oil resistance to cable and to keep off the requirement of damp water-proof function aspect all high especially.
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 good electromagnetic compatibility that has, the main-loop power cable for frequency changer that extends the useful life of cable.
The present invention takes following technical scheme to realize: a kind of main-loop power cable for frequency changer, it is made up of aluminium conductor, inner insulating layer, packed layer, screen, copper conductor, external insulation layer and sheath, described aluminium conductor is wrapped with inner insulating layer and forms three groups of cable cores, three groups of cable cores are wrapped with one deck packed layer, described packed layer outer wrapping one deck screen, is evenly extruded with many copper conductors in described screen.
In described restrictive coating, be furnished with a copper wire drainage thread.
The present invention has following beneficial effect in sum: the present invention has good electromagnetic compatibility, resistance to ag(e)ing and oil resistance, also has good gear tide water-proof function, can protect cable insulation intensity stabilization, the useful life of safe and reliable prolongation cable.
Accompanying drawing explanation
