Description
Technical field
The present invention relates to power transmission technology field, more particularly to a kind of mineral insulated cable for the moisture absorption that blocks water.
Background technology
Mineral insulated cable be there is high conductivity copper to make conductor, electrician is insulated with magnesia powder, anaerobic dephosphorization copper pipe sheath
The inorganic matter cable formed.The inorganic material applied in mineral insulated cable, it is ensured that cable has stability, long lifespan
And fire resistance.But due to the easy moisture absorption of magnesia itself, the insulating properties of magnesia, and existing mineral insulation electricity can be influenceed
The general of cable does not all have block-water performance.
The content of the invention
Based on technical problem existing for above-mentioned background technology, the present invention proposes a kind of mineral insulated cable for the moisture absorption that blocks water,
The cable has good moisture absorption performance, can adsorb the aqueous vapor in magnesia, improve the insulating properties of magnesia, together
When, the cable also has good block-water performance.
The present invention proposes a kind of mineral insulated cable for the moisture absorption that blocks water, including：Conductor, it is coated on the oxidation of conductor periphery
Magnesium insulating packing layer, and the sheath of magnesium oxide insulated packing layer periphery is coated on, wherein, it is distributed with the axial plane of sheath some
Through hole, the periphery of sheath are coated with the first lapping layer, and the first lapping layer is made using impermeable material, the first lapping layer with
Moisture absorption packing layer is provided between sheath, filler is moisture absorption cotton in moisture absorption packing layer；The periphery of first lapping layer be coated with second around
Covering, the second lapping layer are formed using waterstop is laterally wrapped, and tack coat is provided between the second lapping layer and the first lapping layer；The
The periphery of two lapping layers is coated with outer jacket.
Preferably, glass fiber is contained in magnesium oxide insulated packing layer.
Preferably, conductor uses copper conductor.
Preferably, sheath uses copper sheath.
Preferably, the first lapping layer forms using mica tape is laterally wrapped.
The present invention sets moisture absorption packing layer by setting through hole in the axial plane of sheath in the periphery of sheath, and conductor is logical
When electricity operation, the moisture evaporation in magnesium oxide insulated packing layer is formed vapor by heat caused by conductor, and vapor leads to
The through hole crossed on sheath axial plane outwards overflows the moisture absorption packing layer absorption for being covered by sheath periphery, avoids steam from being oxidized again
Magnesium absorbs, it is ensured that magnesia is in drying regime, the insulating properties of magnesia is in optimum state all the time；First in the present invention
Lapping layer is made using impermeable material, and the second lapping layer forms using waterstop is wrapped, and the first lapping layer can stop
Outside water quality is internally permeated, while also avoids waterstop from being influenceed by internal high temperature vapor, influences block-water performance；The present invention is logical
The setting for crossing the first lapping layer and the second lapping layer improves the block-water performance of mineral insulated cable.
