Description
Technical field
This utility model belongs to field of cables, particularly relates to 150kv high direct voltage flexible cable.
Background technology
High direct voltage flexible cable is the series products used in electrical equipment, makees connecting line in the various units needing high direct voltage electric power power supply or instrument.Generally using length the longest, delivering power is little.This series products is not owing to having correlation standard, and therefore this series products exists different defects in manufacturing and designing.In use cause service life short due to the unreasonable of product structure, breakdown accident easily occurs, or there is the appearance such as situation of disturbing other electronic machine.
Utility model content
The purpose of this utility model is to provide the 150kv high direct voltage flexible cable of a kind of life-span length, strong interference immunity.
This utility model takes techniques below scheme to realize: a kind of 150kv high direct voltage flexible cable, it includes conductor, conductor shield, crosslinked polyetylene insulated layer, polyethylene layer, insulation screen, metal screen layer and external sheath layer；Wrapped conductor shield outside described conductor；Crosslinked polyetylene insulated layer it is coated with outside described conductor shield；It is provided with polyethylene layer outside described crosslinked polyetylene insulated layer；Described polyethylene layer is gone out coated insulation screen layer；The metal screen layer of braiding it is provided with outside described insulation screen；The outside wrapped external sheath layer of described metal screen layer.
Described conductor shield and insulation screen are as TPO semiconductive material.
Described metal screen layer is that tinned copper wire braiding forms.
Described restrictive coating is oil resistant flame-proof polyvinyl chloride.
This utility model has the advantages that in sum
This utility model improves cable product quality and service life, reduces the interference to electronic machine.
Accompanying drawing explanation
Fig. 1 is this utility model cross-sectional structure schematic diagram.
Detailed description of the invention
As it is shown in figure 1, a kind of 150kv high direct voltage flexible cable, it is made up of conductor 1 and six layers of external protection.Wrapped conductor shield 2 outside described conductor 1；Crosslinked polyetylene insulated layer 3 it is coated with outside described conductor shield 2；It is provided with polyethylene layer 4 outside described crosslinked polyetylene insulated layer 3；Described polyethylene layer 4 is gone out coated insulation screen layer 5；The metal screen layer 6 of braiding it is provided with outside described insulation screen 5；The outside wrapped external sheath layer 7 of described metal screen layer 6.
Described conductor 1 is the 5 stranded tinned copper conductors of class.
Described conductor shield 2 and insulation screen 5 are as TPO semiconductive material.
Described metal screen layer 6 forms for tinned copper wire braiding.
Described restrictive coating 7 is oil resistant flame-proof polyvinyl chloride.
The conductor 1 that this utility model cable uses is the flexibility that the 5 stranded tinned copper conductors of class ensure that the construction of cable, it is easy to bending, beneficially laying installation.
Conductor shield 2 of the present utility model and insulation screen 5 are as TPO semiconductive material, uniform conductor surface field, and internal layer temperature resistant grade is high, and outer layer temperature resistant grade is low, point bilayer extrusion, are beneficial to control the bias of insulation.
The above is this utility model embodiment, therefore all equivalence changes done according to structure, feature and the principle described in this utility model application range or modification, all it is included in this utility model patent claim.
