Abstract
The utility model discloses a control cable for a transformer station. The control cable for the transformer station solves the problems of the short service life, the high replacing cost and the like of the current transformer station cable, and has the advantages of environmental protection, flame retardation, water resistance, termite prevention, simple structure, long service life and the like. The structure of the control cable for the transformer station comprises that the control cable for the transformer station comprises a plurality of conductors, the plurality of conductors are placed in a filling body, and an outer wall of each conductor is provided with a conductor insulating layer; an outer wall of the filling body is sequentially wrapped by a cable taping layer, a cable shielding layer, and a cable sheath layer; and a conduction line is provided in the cable taping layer.
Description
Technical field
The utility model relates to a kind of cable, especially a kind of transformer station control cables.
Background technology
Transformer station's cable problem in useful life is the most important factor that affects transformer station's normal power supply at present, also is an important step that realizes transformer station's life-cycle management.Transformer station's cable life is short, in case break down, replacement cost is high, and the safe operation of transformer station is brought very large risk.
Chinese patent ZL200810138007.4 discloses a kind of control cable for nuclear power station, it comprises that conductor places in the obturator, the double-deck heterogeneous screen of outer wall parcel cable and the cable duplex sheath layer of described obturator, the outer wall at every conductor also is provided with the conductor double insulating layer simultaneously.But the cable that this patent is announced is without drainage thread, and charge accumulated causes that electric field is concentrated, and the cable anti-electromagnetic interference capability is poor, and the shielding poor stability is not suitable for 500KV transformer station and power plant and other needs anti-forceful electric power interference range.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of transformer station control cables being provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of transformer station control cables comprises some conductors, and described some conductors place in the obturator, and the outer wall of every conductor is equipped with conductor double hyer insulation layer; The outer wall of obturator wraps up tape for cables layer, cable shield and the coat layer of power cable from inside to outside successively; Be provided with drainage thread in the described tape for cables layer.
Described tape for cables layer is fire-retardant gluing type glass strap, and the tape for cables layer adds 7 * 0.25mm
2Drainage thread.
Described cable shield is lapped shielding layer, and lapped shielding layer is compound copper-plastics band.
Described the coat layer of power cable is low-smoke zero-halogen flame-retardant termite-proof polyolefin jacket layer.
Described conductor double hyer insulation layer is primary insulation and outer layer insulation; Wherein, primary insulation is the IXPE insulating barrier, and outer layer insulation is the irradiated crosslinking low-smoke and halogen-free polyolefin insulation layer.
Transformer station of the present utility model high performance control cable, internal layer are the IXPE Insulation Material, and skin is irradiated crosslinking low-smoke and halogen-free polyolefin insulation material; Sheath is the low-smoke zero-halogen flame-retardant termite-proof polyolefin jacket material.
The tape for cables layer is fire-retardant gluing type glass strap, makes flame retardant effect better reliable, and belting layer adds 7 * 0.25mm
2Drainage thread.
Cable shield adopts compound copper-plastics band, makes shield effectiveness more reliable.
Compound copper-plastics band
The wrapped shielding of compound copper-plastics band namely has the shielding properties of copper strips, contains again and moulds the band mechanical stress, makes screen more firm, reliable.
Insulation Material adopts the IXPE Insulation Material, has improved the electrical property of product, has reduced dielectric loss in use, makes signal transmission more stable, reliable, thereby has ensured effective transmission of cable;
The beneficial effects of the utility model are: environmental protection, and fire-retardant, termite-proof, simple in structure, long service life, working stability is reliable.
