Description
Technical field
This utility model belongs to field of cable technology, especially relates to a kind of frequency-changing cable.
Background technology
Frequency conversion system the most often high speed, frequent frequency conversion; frequency conversion system can be caused damage by the pulse voltage produced, and traditional frequency-changing cable prevents Electromagnetic Interference performance not strong, and its three-phase balance is poor; proof voltage impact is the strongest, it is impossible to play a good protection；And existing frequency-changing cable water resistance is poor, when mechanical stress or external force cause cable cover(ing) and insulation harm or joint failure, moisture or moisture can immerse along cable longitudinally and radially gap, and cause cable insulation to puncture in the short period, cause power outage；And during transporting, installing and use, cable easily causes damage, therefore to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that a kind of frequency-changing cable, it have interference free performance preferably, three-phase balance preferably, proof voltage impact is relatively strong, good water-proof effect and the feature of good fire resistance.
In order to realize above-mentioned purpose, this utility model be the technical scheme is that a kind of frequency-changing cable, the outer jacket including cable core, being coated on outside cable core and be filled in the packed layer between cable core and outer jacket；Described cable core includes master core, neutral core and wire core；Described master core is coated with master core screen layer；Described packed layer is outside equipped with lapping layer；Described lapping layer and outer jacket are provided with screen layer；The material of described outer jacket uses high-density polyethylene material；Described outer jacket is coated with aluminium alloy armored sheath.
Described packed layer is flame-proof glass fibre rope packed layer.
Described master core includes master core conductor and is coated on the master core insulating barrier of master core conductor periphery；Described neutral core includes neutral conductor core conductor and is coated on the neutral conductor core insulation layer of neutral conductor core conductor periphery；Described wire core includes wire core conductor and is coated on the wire core insulating barrier of wire core conductor periphery.
Described master core, neutral core, wire core are distributed in equilateral triangle respectively.
Described screen layer includes proof copper-wire braided layer and copper strip shielding layer.
After using said structure, compared to the prior art this utility model has the advantage, that this utility model simple in construction, uses three master cores to add three neutral cores and adds the symmetrical structure of three wire core, improves the proof voltage impact of this frequency-changing cable；By master core screen layer and shielding layer structure, can well prevent the interference of electromagnetic wave, shield effectiveness is good；The material of outer jacket uses high-density polyethylene material, has excellent resistance to low temperature, and chemical stability is good, is resistant to the erosion of most of soda acid, and insoluble in common solvent under room temperature, water absorption is little, and water resistance is good；Aluminium alloy armored sheath intensity is high, peel off easily and flexibility is good, does not easily cause damage and have good fire resistance during transporting, installing and use.
Accompanying drawing explanation
